Don't worry, I didn't travel to New Jersey just for this; I was in the area and it seemed like an apt location. I did try to remove the truck-reversing sound near the end, but it just sounded worse: and given what I was talking about at the time, that also felt apt!
Hi
Hi
Good, no one should have to travel to New Jersey
hello
3 days ago??
Telling the audience that you're doing a thing to subtly manipulate them, and how and why it works, with no intent to stop because it DOES work, thus establishing trust by being forthright about a lie to establish trust is probably about the most Tom Scott thing ever.
The best tricks still work even once you know what's going on.
That was absolutely incredible
Is it really manipulation though if it's both for the purpose of synchronization and gaining the trust of the viewer, showing that you care?
Bit of Penn & Teller vibe there.
â@@Yossus "You don't really want to know. You want to be fooled." - The Prestige
The wave to the crewmembers who may or may not have been there is an absolute masterpiece of subversion, creating just a tiny bit of doubt.
Not gonna lie, if at the end the camera turned and showed 40 people, all doing a different big-film crew's task it would've been a funny skit. Reminiscent of open-broadcast TV era shenanigans.
I was really hoping for a single hand to emerge off-camera, give a little wave đ or a thumbs up đ and then disappear at that point.
If I had to guess, that was probably either him waving to a random passerby that just happened to be there at the right moment (like the truck backing up a little earlier) or him just making a joke- although it would be hilarious if he finished talking and the background image ended to reveal the green screen and then the camera panned to show the studio set that is very much not New Jersey
Youâre very easy to impress.
Part of me was hoping there'd be a cut to show Tom actually in front of a green screen!
I have an auditory processing disorder. I noticed the lack of sync immediately, because of being so used to reading lips and searching for visual cues. Also, knowing Tom Scott, I was kinda expecting it to be unsynchronized on purpose. Very cool video.
Funny, I have an APD too and I didn't notice it because I was too busy reading the subtitles haha
Yup, noticed the lip sync was wrong too!
I noticed the lip synch too, makes so much sense now. So many videos are out of synch for me and it really frustrates me to the point of exiting a video
@@lizthegrey same
i think i have an apd but i can't tell when things are delayed, at least not here, when things are supposedly synced perfectly because there's a big production crew (like if i'm watching tv shows or something) it looks unnatural and unsynced even if it might be đ
I love how the most replayed part is Tom talking about the 3 frames late, meaning most people decided to go back a few seconds to see if they can catch the 3-frame lag
as opposed to most videos where the most replayed portion is the ad⊠because apparently Tom is really good at delivering ad reads? I donât understand this fanbaseâŠ
@@KufLMAO i feel that people do +10 -10 to see when the add ends and the video starts and that counts as rewatches
â@@snomandonly that should tell many youtubers something
Hey, where can you see that? That's a really interesting fact to know about videos
@@tywinderbaum5283 I used to be able to see it on a custom app, but it should also be on desktop youtube when you go back and forth on the video time.
I respect the hell out of Tom every time he pulls a baller move like giving exactly the solution you're looking for within 10 seconds of the video starting, trusting you to be patient enough to wait through the rest just because you seek the pleasure of learning something
Tom Scott is a national treasure
Can we share?
THIS
@@YTPEXPERT correction: Tom Scott is an _international_ treasure
I learned he might not be as smart as I thought he was. Nothing he claims in this video appears to be confirmed by facts.
"I don't want to be relatable, I want to be trustworthy" - I think this is why we all love Tom.
It's also why he's really relatable.
I relate to his not wanting to be relatable, but I don't trust his claim to wanting to be trustworthy
@@Irys1997 : He's lying, cos he is using our collective data, and then creating that same thing which we either have done ourselves, or that it is part of our own experiences.... so in a way... this is not creating trustworthiness, this is creating relatable experiences, for HIM. Not for us. Never knew that YT is so big... or that people have been using it for so long.
Well, it is always going to be tough to relate to someone who landed in Groverâs Mill in 1938, but it doesnât mean we canât trust them.
I don't love Tom, not to say I dislike him or anything, although I do frequently find him annoying. He does often present interesting information though.
I must admit after hearing the truck sound and talking about setting the scene, I totally expected you to walk away and reveal it was a green screen afterall.
yea, same here
dont know if its just in my imagination, but right after that, i thought, the lighting on tom looks also kind of "off" for some reason
@@brokenai9496 yup same.
haha same here!
i was making sure branches are moving to know it's not static image
@@fistsofsnake5475 crazy thing is that even if the branches were moving, it can still be a green screen. You can put video up on a green screen
Tom always impresses me with those incredibly long shots of him talking. I can't imagine how hard it is to not slip up for that long.
Luckily for him, he can try again as many times as he needs and we'll be none the wiser.
It's extremely easy. If you mess it up, you can just hit delete and then do it again.
As I've said for years: the best production value isn't always the _highest_ production value. It depends on the audience, the message, and the format
Good message Doctor Clark
Highly recommend everyone watch the Red Letter Media Best of the Worst where they film everything with VHS cameras but use decent mics. That video is the perfect example of that.
(I don't anyone will actually go watch it but just in case, the title is: _Best of the Worst: Night of the Lepus, Zombie 3, and Silk_
oh its that cool climate guy Im subbed to
For example, I sometimes much more greatly enjoy seeing jankily made but passionate ads from small things with small budgets than generic high-budget ads from large companies which are practically all the same predictable minimalistic professional style.
Great take Dr Simon Clark
What I love is that he not only answers the question, but he does it in such a way I don't want to skip to the end.
@Emily An Didn't know you liked Mara Jade that much
@Emily An bot
@@puppergump4117 HAHA
What is your attention span like bro
One of the many things I love about Tom Scott is that often when thereâs a question implied in the title, he will actually answer it at the START of the video. Like he did with the floating by helium balloons! Just one of the many things he does that are genuine quality :)
The three frame delay is so confusing to me because I felt something was off with the synchronization even before he said it but when actively trying to match the sound to the video I couldnât see the delay at all.
Right? and it was so much smoother when it went back.
I get a weird uneasiness sometimes with poorly synced audio. I did this time, was actually noticing in real-time, and only realized why after you explaining and changing it back a few seconds later. Certainly confirmed a lot for me and possibly explained why at times Iâll find a video I just find unsettling to watch for unapparent reasons.
probably due to aliens
So true
Same. All the pieces fell together when he said there was a lag. I will be more observant of this from now on.
I really appreciate how he gets straight to the point for people who are just curious then goes into all the details and stuff through the rest of the video
Well, he doesn't really, considering the thumbnail "It's probably not what you think". He gets _that_ out of the way immediately.
@@607 He does not get straight to the point, but he does explain the answer in a very short amount of time. It can still be appreciated.
@@pliktl wym
@@mihailmilev9909 balls
He gets to the point at 2:33, ~2/3rds of the way through the video.
I cannot tell you how many times I have wondered why film crews use clapper boards, which of course, I've never actually seen in person, but every time I see one in a film or documentary that uses one that is digitized, I wondered why such a manually-operated feature was still needed and now I know. Thank you, Tom.
If you see a modern clapper board you might see that they also have what's known as a timecode running on it. Timecode is in the format HH:MM:SS:FF (for hours, minutes, seconds, and frames (sometimes the last : is a ; for reasons it's not helpful to mention here) ). Assuming it's properly synchronised each frame of video should see a unique timecode on the clapper board and multiple cameras can then easily be synchronised without needing to record audio or find the actual CLACK, you just look at what's on the board for whichever frame you have and you know the offset.
Film crews use clapper boards to synchronize audio to video.
@@Milamberinx Still have my chalkboard clapper...... a new one would be nice......
It's also fun to see how many takes a shot took when they show the clapper board. A notable example is OK GO's "I won't let you down" music video, which was done all in one go. From the board you can see it took them 127 takes!
FYI the electronic clapper boards are really expensive, as in, the small one is somewhere around $800 USD iirc. They have a wireless receiver that gets information from another specialized bit of kit which can be attached to high end cinema cameras. On those cameras, there's a port that sends out accurate timecode. The slate can also send timecode and audio blips to a separate video recorder, which means there is 0 slip when synching the audio in the edit booth. This precision allows auto synch features to work really well, but without it, the manual synching method that Tom shows is still perfectly acceptable.
Honestly Tom you have been a standard of what youtube videos can be and how they should cater to their audience, thank you for all that you do.
My new favorite thing that Tom does is answer the video title question we all read in our heads when the video starts. Its like he's answering our inner monologue.
This video is the definition of "anti clickbait". Didn't even read the question from the title back, straight to the point. Why can't all YTers be like this.
No, it isn't, it WAS exactly what I expected.
because its not as profitable as a full video
love your pfp
Except that wasn't the answer to the question in the title. The question he answered is slightly, but meaningfully different.
I actually had to go back and read the title again haha I was confused đ
Thanks for clearing up why I feel vaguely insane for audio and lip syncing discrepancies (I wear HAs and heavily reliant on lip reading so I catch the spots where audios doesnât quite match the video, but it hard to quantify so I just feel vaguely insane 90% of the times it happenđ especially cause it doesn't bother all of my hearing friends less)
Same, but this time I actually didn't notice until Tom said it since I was watching with subtitles and focusing on them instead haha
Haha I love the ending "you can trust me..." on a panning shot to the Martian landing plaque. Odd nobody else seems to have commented on that! I'm guessing it has something to do with War of the Worlds?
Also, interesting to me, the audio you said was 3 frames late looked more natural to me than the audio when it was supposed to be exactly synchronised, even though it was quite a close shot and the delay due to speed of sound should have been about 1 frame.
I was expecting the camera to pull back and reveal a crew of 20+ people when Tom said "You can trust me."
you.. you... you're the portal 2 music guy !
I was not expecting you to respond to a video like this!
I expected him to actually be on a green screen or something.
I was expecting a full green screen reveal at the end.
I mean, he did immediately cut to "MARTIAN LANDING SITE" after saying it! I thought that was funny
Same thing is huge in music. Alot of songs start with the drummer counting everyone in or even the band talking before the song, even on studio recordings. Gives it a human touch.
Good point.
Thatâs a great comparison. They could easily cut it out but they choose not to.
The intro to âSweet Home Alabamaâ, when Ronnie says âturn it upâ, heâs telling the engineer to make his headphones louder.
@@matthewbrotman2907 I always thought that was an instruction to the listener.
I am going to keep following that instruction whether it is meant for me or not.
Leper Messiah by Metallica starts with Lars Ulrich counting.
Even though I knew the answer before I still clicked on the video to hear Tom's way of explaining it.
This video is like a paradox and my brain hurts from all the meta. Well done!
It's amazing how Tom manages to look like he's both in his 20's and in his 60's at the same time
Wow, it's almost like he's 40 years old!
@@AbductingTheAliens No, youtubers dont age!
@@AbductingTheAliens That's not how ages work, though.
That's what a colorful simple tshirt and a pair of jeans does. While in the 50's even young adults were suits and looked old.
@@Marcelelias11 , since heâs 38, they arenât wrong.
thank you for the clarification i finally understand myself fully
What an unexpected place to encounter a dodie in the wild haha
I did actually think about your videos when watching this video. You probably have the most pronounced clapping of the videos I watch :D
hey checkmark
You mean you *donât* do it for the sound sync? đ
I mean honestly the number of things people do simply because they've seen people in that scenario do it while having no idea what the actual reason is...
It certainly can lead to some interesting myths and habits heh
Tom, thank you so much! These appear to be simple concepts, but really are much deeper than I knew.
This is all great stuff, thank you!
Tom, your videos are great, so informative and explained in a why that anyone can understand, and you cover such a great range of topics, I love them!
100ms (or ~6 frames) is actually roughly the upper limit where most people tend to notice audio and video are desynchronized, as long as you're dealing with something like talking. This comes up a lot when building VR environments where you're trying have a central server match up audio and facial animations for a lot of clients. Source: former VR developer.
Are players more or less forgiving of audio delay if they can't see lip movements?
KidHeracles Feel like the answer should be obvious, but it's obviously way easier to tell when you can see the lips. Could have two seconds of delay without having any clue if the visual that's meant to be synced doesn't show what's producing the sound.
The other interesting thing is how we have almost zero tolerance to the audio coming before the video.
@@barongerhardt Indeed, we are really good at picking up things that can't exist in the real world. However, nobody knows why. What evolutionary advantage does it have to detect things that cannot exist?
Plenty of research does exist detailing the time of sensory reception, perception and ultimately awareness.
The lighting on Tom looks so perfect in this video that I was convinced he was going to reveal that it *had been* a green screen the whole time.
"If you did actually notice, well done - I'll teleport back to New Jersey now"
Some people just look green-screen. (Hi Fraser, if you're seeing this.)
I thought the white-balance looked really weird on this video -- more blue/gray than usual.
Glad I'm not the only one who had that same paranoid feeling.. still not entirely convinced he didn't pull an inside joke. Regardless, I have seen scenes, for which I know there were real, which still looked like they were made with a green screen. I guess our expectations can play a trick on our psychology, maybe even perception itself, too.
Oh god, now I'm remember that one video on Daily Dose of Internet, where the guy was demonstrating how his face, glasses, background, and even pointer dots weren't real, even though they were all completely realistic
I see this in documentaries as well. Setting up, makes sense in that kind of production.
In my videos, I donât really think âI want people to think Iâm trustworthy!â Although I understand what it comes from. I find it to be more âhis is how I got hereâ instead of plopping up from nothing or switching place all of a sudden. Not every time, but often I think of it more as a way to tell time and help with glueing the vlog or whatever together.
Interesting and well done, as usual!
that's why I love your videos: no cuts, straight forward, that truck backing up...just leave all in.
Holy crap that extra sound delay you added in after cutting back was having me question myself and I thought I was going mad that I noticed it was now "off" but it didn't seem it before. Really great practical demonstration
I noticed it too. I wasn't 100%, but I did have time to figure that it was in character for Tom to put that in intentionally :)
I only noticed when he claimed to fix it and I thought I was going crazy and it was just the inherent effect of sound coming from headphones on the side of my head while the visual is in front so it feels disjointed.
I Noticed the Audio-Video Sync was a Little bit off In the Middle, but I thought it was because I was Tired, until Tom Revealed the Audio Delay.
Itâs Particularly Perceptible At 1:11, when He Says âOld Go-Prosâ.
I too felt that something was off. I even double-checked whether the video was accidentally playing at 1.25x speed (which I had used recently on another video).
Dang, this did more for me than the "Why you can't trust me" video. Saying you want to seem more trustworthy implies you aren't already, but the transparency in turn makes it true. Genius.
In case some people don't catch the irony of showing the monument in the end of the video, in 1938 Orson Welles did a radio theater adaptation of H.G. Wells' "The War of the Worlds"... except he didn't tell the audience at the beginning that it was just a theater show, so people across the country started panicking because they thought a real life alien invasion was underway. People at the time got much of their news from radio, and Welles created a show that used theatrical authenticity to exploit the audience's trust in radio as a news medium, while here, Tom is demonstrating how he uses theatrics to create authentic trust between himself and the viewer.
Thanks to you because now I am aware of why Tom showed that sculpture at the end of the video đ
Slightly Wrong! They DID in fact tell folks it was a Broadcast of Mercury Radio Theater. The issue was they Never repeated that fact, so folks tuning in later didn't know.
An additional irony is that the War of the World's broadcast didn't actually cause a panic! Or at least, there's no evidence that such a panic took place. It was a story made up and passed on a fact because it's too good to check.
@@blueegg4198 While it's true it didn't cause a wide spread panic, it did cause a bit of mayhem till folks realized it wasn't real.
I heard that the widespread panic is a myth created after the fact, just to fabricate an interesting story. Radio plays were commonplace and people were apparently familiar enough with this medium to realise that The War of the Worlds was fictional.
"Answering the question that was asked" and why a lot of people don't do it in general could be an entire topic in itself. Thank you!
Leave it to Tom Scott to make a video about literal audio syncing, not clickbait it, and still manage to get over a million views with every video
I feel like the "It's not what you think" is a clickbait thing to add
@@Liggliluff ok but was it the thing you thought it was going to be
@@Liggliluff clickbait is when you lie about the thing you are showing in the media. Tom did not lie but told the exact reason why he did it
Except it's not about audio sync, at least not the part where he answers the actual question.
@@Arnav150
Not quite true. Clickbait is literally what it says: something (usually a title or thumbnail) to bait people into clicking on the video.
Nowhere in there does it say anything about it needing to be a lie.
I feel like the same can apply to leaving small audio/video bloopers in towards the end of a video, making it feel as though it's not always a perfectionist idea that the final product has to be perfect and without the occasional slip up!
Technology Connections comes to mind
Would've been so good if he actually was in his room using a green screen
I expected the camera to pull back and reveal a big green screen behind him and a bunch of crew members and equipment
He was.
@@someguy9778 trust me bro
The human connection point about behind-the-scenes is demonstrated really well in Joel Haver's videos. The slip-ups and smirks that he deliberately leaves in just make it all the more endearing.
Lindsey Ellis did a huge (video)essay on the manufactured authenticity of youtube videos. It dives a bit more deeper into ideas like "calls to action" which thankfully Tom did not have in this video. Also the mid video outtake and off script remarks are being analyzed in the essay too
"Be sure to like and subscribe!"
I do hope that the remarks aren't being "analized" without their consent.
That's exactly what came to mind when watching this video. In fact I half wondered if the sound of the truck backing up wasn't just added in to make it more relatable
That video is great
whats the video called?
Editor here: that audio desync was driving me insane! I figured it was an intentional joke, since most people wouldn't pick up on it, and then the big reveal came out. Well done.
I know you've probably heard it before but thank you so much for just answering the title immediately in your videos. Honestly its what gets me to stick around, because now I'm more intrigued to know _why_
Serious question, is this a script you've had in your back pocket for those situations where you go to say a Martian landing site and it turns out to not really be interesting enough for its own video, or the local expert calls in sick and you can't make a recording on the topic you meant to? Do you have a backlog or list of these like the list of bad ideas if so?
I would not be surprised if there's a War of the Worlds relevant video coming soon (presumably about the "panic that never happened" or about microbiology). Or maybe he was visiting Princeton for a vid.
@@pavarottiaardvark3431 Exactly mate. Even if the site itself turns out to be a disappointment it still makes it a worthwhile introduction to do a video on 'War of the Worlds'. He wouldn't really need a back up.
This makes sense, since I don't think Tom has clapped at the start of one of his videos for a while. This might be an idea he's kept in his back pocket for a while
The War of the Worlds radio show panic is a bit well-known for Tom Scott, I'm sure there are a dozen decent CZcams documentaries about it. I expect he chose it mostly for the humor value of finding out what the plaque in the background is, after a video about trustworthiness and authenticity.
The ideas board.
What a brilliant reveal at 3:34!!! Going all the way to Grover's Mill, NJ just to use the War of the Worlds plaque as subtle allusion to the most relevant radio broadcast in regard to media and trustworthiness. A meta touch that would make Orson Welles proud.
3:02 "i don't want to be relatable" i can relate to that
You missed the point
Task failed successfully
i love how he just got straight to the point
This makes so much sense. It gives off the idea that this CZcamsr could be one of your friends making a video in their bedroom, sells on the idea that it's not a corporate personality talking to you, but a genuine person who isn't a professional in video making.
I'd say this is why a lot of CZcamsrs that are more gameplay than live action make jokes in their videos about how video editing is hard or how much time they will need to do X thing, because it helps sell the idea that this isn't a highly curated video made by tons of editors (even when it is) but by just a random person.
It's the idea of "The next famous person could be anyone, could be you, could be a friend, or a family member!!"
ah. it seems i'm intuitively aware of this because i tend to get VERY irritated by those types of personalities. you can tell it's manipulative and designed to make you trust them.
@@abbiepancakeeater52 That's good!
Itâs crazy but I actually did notice the three frames off (I didnât have a count but I knew something was a bit off) before you said. Also I learned about the clapping in video production class in high school, so I think itâs very cool to also hear it from a CZcamsr as not everyone has the opportunity for a video production class.
Me too. I think I must be sensitive to it for some reason because it drives me crazy when the sync is just a tiny bit off, like watching on someoneâs âcheap soundbarâ setup like he mentioned, it just continuously annoys me until I have to turn it off.
I didn't notice the three frames off until the moment he fixed it. Instantly my brain went into freefall because the timing had changed. I had to pause the video and clear my head so that my brain stopped trying to compensate for the delay.
Did you notice the green-screen?
â@@isakoolsson Nope but I did have a split second of "Something looks off". CG I can recognize from a mile away, but green screen I'm usually wrong unless its really, REEEEALLY bad.
@@McTeddyGames And you genuinely believe that 3 frames of audio delay made you have to pause the video and clear your head? Thats the amount it takes for sound to travel like 30 meters lmao
Your videos are a land of answers to questions I never knew I had, and I love it.
Tom is always answering questions I never knew I had until he posts a video đ
Tom Scott 3 years ago: Why you can't trust me
Tom Scott now: It's ok, you can trust me
Character development
Well, his whole brand depends on people thinking we can trust him...
Cue _Sledge Hammer_ intro music.
"It's okay, you can trust me" he states while standing by a monument stating that place is where the Martians landed :D
Alternative Tom Scott now: This is how I convince you to trust me even when you maybe shouldn't
@@Ironica82 But Martians did land there in 1938...in Orson Welles' broadcast of _War of the Worlds._
I do it because I love starting my videos with a standing ovation.
you didn't mention an additional issue that we subconsciously correct during editing: our ears perceive sound faster than eyes perceive images, so a "perfect" sync on paper will still look weird, whereas if you delay the audio just by 1 or 2 frames, it will compensate the "slowness" of the eyes, and they will meet in the brain at the same time, resulting in a more natural synchronization. in short, each sense has its own delay times, hope this helps.
Light is faster than sound though ?
@@quartzmerlin Yes, it is. What this person is saying, though, is that the internal processing within our brains is slower for sight than sound. It may reach our head faster, but our brain thinks about it longer.
@@hiimcrazyfordrwho Very interesting, thank you.
As a rhythm game enjoyer, this really makes me think. I'll usually play on the same delay settings, but sometimes it randomly feels slightly off and I need to change it by 5ms to feel normal again. I always attributed it to my device randomly running slightly slower, but maybe sometimes it's just my internal mind running slower or faster
This was such a great video. Quick, interesting, informative, and it let us learn a bit more about you and how you approach making videos :)
I love the authenticity !! It makes it much more personable and almost comforting in a strange way. Tom you never miss fr
If you're dong stuff like this to appear authentic, it arguably makes it less authentic. It's literally planned out to set a certain tone.
Not to say I don't like it, I do.
@@Nostalgia1709 I think it's less contrived than that. This video aside, its likely more of an editing choice than a "planned" bit.
â@@Nostalgia1709 Always remember it takes a lot of effort to make it look effortless.

third like
@@thespectrum630 you can't be the third like, *I'M* the third like! ~starts slap fight~
Thank you Tom for your work and your videos!
Gotta LOVE the "You can trust me" followed by that plaque XD You never cease to amaze us, Tom
"you can trust me" and then cutting to 'martian landing site' was brilliant
You're everywhere !!! How come ?
The little wave after "sometimes I leave that in even when I do have a crew" really sells the trust angle đ€Ł
I've been curious about this for a while; thanks for the information!!
All the fancy audio mixing you did here and there feels like a flex
I always just thought the clapping was there to get your attention, but this video is really cool!
I love how he just answers the question right away and still manages to keep us watching the whole video
I love this format of immediately answering the question in the title and then going more in depth. Tom is an amazing youtuber.
I don't even have words for that ending. That was too perfect, Scott. Too perfect XD
I didn't really notice you doing this before. But now I'm rewatching your videos, and notice every time
I thought he was about to say, âAnd Iâm actually in front of a green screen.â until I heard the truck reversing. But then my mind thought, âOf course he would add that in to trick us into thinking itâs real!â
Now I just have terrible trust issues.
I too was almost certain the beeps were added in and he'd say something like "interruptions like this truck assure you that I'm actually here on location, even though we added them in editing"
I tend to snap my fingers in front of the camera instead. for syncing. I find with clapping it can be hard to determine if the hands have made contact yet. With a finger snap, your fingers instantly move from one position to the next, making it obvious where to sync to. Mostly just use the audio peaks though.
Thank you so much for explaining this.
This is very helpful
You're such a troll and I love it - cutting from "it's ok, you can trust me" to the Martian Landing Site board is perfection! XD
As a deaf person any messing around with the link between sound and video is often picked up straight away as deaf people use lip reading and body language heavily and the brain somehow merges it with what audio we are receiving and tries to put it all together very fast for us to get the gist of what is being said, when there is a lag it immediately makes the process much harder and more tiring, so I can confirm these things do matter and the slippage in the video was really noticeable :-)
yes and someone saying to me âoh it doesnât matter, just get it uploadedâ drives me batty precisely because someone out there needs the perfect synchronization.
I thought in English being deaf means that you don't hear anything.
@@cyan_oxy6734 Technically, it can simply mean having a hearing impairment (Oxford Languages), however, I still fail to see how less hearing makes lip-reading harder. Then again, Stuart Russo is hearing-impaired, so there you have it.
@@cyan_oxy6734 same goes for "blind". Most blind people can still see something, just a lot less than a seeing person. Same for "color blind", most only can't differentiate red and green
@@cyan_oxy6734 same here I was like, only worse, wait I thought these guys don't seeđ
Psychoacoustics are kinda crazy. When in school for sound design we spent a lot of time talking about how ears and brains actually perceive audio. Things like manipulating delay can have a huge impact on the end experience.
Did you go over the McGurk effect? That blew my mind in the phonetics course I took as an elective!
This was so thoughtful and brief!! I really miss CZcams videos being like this.
"I don't need to be relatable. I don't really want to be relatable." I have never heard Tom sum up so succinctly the difference between how he uses youtube and how most other youtubers use it.
Wasn't aware that THAT much could go into sound synchronization. Fantastic work as always, Tom.
On professional film sets, people use "timecode" which costs literally thousands of dollars and only exists so editors don't need to sync claps and it can all happen automatically
In the silent era they used slates to mark different scenes. Once audio was introduced and syncing became important, a piece of wood on a hinge was added to the slate and we got the clapper board (aka. Klaff).
I think the degree of sensitivity to video-sound asynchronicity can differ culturally: I live in a country where the majority of English-language films and TV are dubbed into the local language, so people are used to seeing lips and words not in synch. Iâve noticed that film professionals - possibly as a consequence of this - arenât terribly precise about synching in the local language either, when there ought to be a match.
Animation also often has terrible lip syncing because animating lips is very tedious. I've noticed that western animation tends to put more effort into lip syncing than Japanese anmiation, though.
@@poudink5791 I think in western film making people are getting so much into the technical nitty gritty that they forget that they also need a good story. Like how "Legend of Korra" had the most frames drawn for an animation series ever but the writing and lore was lacking and somewhat squandered at times.
@@cyan_oxy6734 I mean, different people are responsible for the animation and the story so I'm not sure how connected those two are.
Awesome video once again Tom. Love it!
You keep on proving why you are my favorite CZcamsr here.
I always figured it was like a clapper in a movie, just less formal. I was just explaining this to a friend while we watched your videos the other day. Thanks for the concise answer to a question that was on our minds!
but the point is explaining why it is left in the final video
I mean it is, that's why clappers were introduced, at least that's the technical reason.
@@hedgehog3180 The other, more important reason is that they're fun
Love these tricks in videography, here in photography we also have similar tricks such as utilising a far away object like a lamppost or car to make the viewer naturally concentrate more on the details.
I got so worried when the audio become out of sync, glad to know it was on purpose.
Working like charm !!!! thanks for sharing and keep up !!!
Tom Scott 3 years ago : âwhy you canât trust meâ
Tom Scott now : âitâs okay, you can trust meâ
We used to call this "double-system sound" in the 16mm film days. Much as Tom is doing here, we had a sound recorder separate from the camera, usually a Nagra or some other high-quality (ie, "expensive") type. Sync was either with a cable connecting the camera and recorder or motors on both devices controlled by crystals that kept the speed constant. In post, we transferred the sound from 1/4-inch, reel-to-reel tapes to 16mm film that was coated with magnetic recording material. That way there was a frame-for-frame match between picture and sound. Of course, it took a lot of machinery to make this happen, and that's why movies with sound were beyond the range of most people. Thanks, Tom.
I'm so glad you gave us a look at that placcard behind you. I was wondering what that was and thought that might be a flying saucer on it. Now I gotta go look up what it's all about. Thank you!
As an editor, I noticed the 3 frame lag instantly, thank you for restoring it đ
Yes, I did notice the lag and immediately thought you had made an editing mistake. But it was not a mistake. Fun video. Especially the idea of long range shots actually needing to be synced differently for effect.
I noticed the lag too but only because I had the thought of checking his mouth very closely at that exact point in the video. Tom had that very well timed for me!
Same. I noticed it before he mentioned it because I expected him to do something like that. I mean... that's just such a Tom Scott thing to do.
I noticed but when he said that sound may feel weird if the camera is far away and how much delay the audio should suffer if we were there in person etc., I thought that was it. So he subverted my expectations twice with the same trick
I was in the middle of trying to figure out if the audio was actually ahead or behind the video when he mentioned it.
I thought it was wrong on purpose to set up a punchline later, which I guess is true but not the way i imagined :p
Tom 2022: You can trust me.
Tom 2019: You can't trust me.
"You shouldn't trust me but I'm going to make that as hard as I can"
I think the Orson Welles "War of the Worlds " reference at the end is a suble reminder that just because he makes himself seem trustworthy doesn't mean he is. Many people thought the 1938 broadcast was trustworthy...
"I don't need to be relatable. I don't really...want to be relatable."
I can relate to that. đ¶đ

I love how your videos start with the direct answer now. Makes you more trustworthy in a world of clickbaits
I really like the recent videos where Tom just straight up gives the answer as the video begins. Great work!
It's the same writing format as news articles: start off with the most important things, and then work down to the details. It's effective at getting a message across quickly and transparently. There has been a bit of a trend with youtubers doing that, and I really hope it catches on more.
Wow⊠that plaque at the end IS AMAZING!!! That is so so cool!!!
The focus on this video is so crisp I was half expecting a greenscreen reveal at the end.
I actually didn't know that it was essentially just a makeshift Clapper board. I just through it was a way of say "Go" to the camera person to let them know you are ready now. Great explanation on how this works.
Also I literally just noticed that the audio was off when you mentioned it and my brain just immediately made it look weird.
I noticed a slight lag right away and had a barely conscious thought wondering if it was a mistake or intentional (or youtube issue, cause that happens) before just ignoring it, then he said so and I was like oooooh. :D
I didn't even know that clapper boards are used for sound and not really just the information written on them.
Same here with the audio, I was fine with it, until he said it was off and then I noticed it, then even rewinding it after it was pointed out couldn't not see/hear it.
@@takahashi2852 They're used for both! After recording when you pass info to the editor, especially back in the film days, if you thought take 2 or 3 of a shot was really good but there was a part of take 5 that was good on it's own, it was helpful for the editor to be able to quickly scrub the reel to find the correct takes, and then the audio's there to help sync it when it's being recorded to the master.
I noticed that lag 10s before he said
I love that you ended a video on something relatively benign as clapping, with a shot of a "Martian Landing Site" memorial.
Now I wanna know all about that as well!
The clue is in the art on the memorial statue. It's the town named as the landing site in Orson Welles' radio production of War of the Worlds. In HG Wells' War of the Worlds, the invasion (as far as the narrator sees) starts at Horsell Common outside of Surrey before progressing toward major cities. In the adaptation, Orson Welles chose Grover's Mill as a bucolic landing site from which the Martians would then progress toward nearby cities Trenton and Philadelphia.
Thank you for helping resolve my sanity by clarifying it was 3 frames late; it's funny how that TINY amount of desync can offset the video and audio enough to feel like it's a voiceover instead.
You're amazing Tom, I really thought I knew the reason, but this was philosophy
I heard it described once that if you didn't know about the discrepancy between the speed of sound and that of light then if you were watching a lumberjack work across the valley you might think that an axe was a device that makes a loud sound when held above the head. đȘ”
Edit: Also, an actual filmmaker's clapperboard not only makes a sharper peak in the audio, those chevrons on the clapper shows the exact moment when they touch allowing much finer synchronisation than with the hand technique.
