I like the new visualizer very much. But I think it could be worth a try, to overlay it with a transparent or outlined version of the full logo, so that it does not look cut-off most of the time. Instead it would look more like a level meter with a fixed scale.
Yes, I'm also thinking along these lines. Probably not too hard to achieve.
@@DanWorrall I'd say not too hard is an understatement. All you need is an outline of the logo in .PNG so transparency in the center is preserved, and a video editing software that allows layering multiple images on top of each other (which I'm pretty sure is almost all of them), then it's just a matter of putting the outline image on top, aligning them, and you're done.
... even it would be a black screen... I'm Here for knowledge.
thanks for everything Dan.
On top of this, it would be nice to have the background be something other than pure black. Something like some blurred-out mix of pastel colors or just whites and grays, and the logo being sharp would make for a nice backdrop.
Honestly, if he just made the colour changes more responsive/sensitive to the input of his voice, I think it'd look much better.
I quite like the new visualiser, perhaps more than the old one. I think it suits the channel. Once again thanks Dan for being as informative as ever
Absolutely, to me it's a lot nicer to look at than the old one!
The new visualizer is cool, but I think the waveform does a better job capturing what your channel is about. Also, as someone else said -- more interesting to look at.
Yep, The waveform has become a signature
I think the waveform was too distracting and annoying and it had to look away. This is much better imo
If it takes 5x time to render because of waveform (and it does), ignore it
same, the waveform hasn't got your name on it, but it is something i got used to and now associate with your voice.
@@Flobyby Dan “has become a waveform” 😹 In the metaverse, Dan is a waveform, to us, in our collective consciousness 😹👽
It's always good when a CZcamsr updates in light of new information - too many get ratty or quibble regardless of how politely they have been contradicted. The ability to accept this just adds to your reputation.
I like this new visualizer thingy
You’re a legend Dan. Great teachers always admit their mistakes.
I remember when Kenny Gioia started showing his face on his Reaper tutorials and a part of me always wondered what kind of guy Kenny was. While listening to his accent, I imagined him being this really tough guy from the Bronx running a community audio studio for the youth usually engulfed in gang wars and drugs. Alas, reality was less entertaining even though I still believe Kenny is a superhero of sorts. (He has helped me learn Reaper to a fairly profficient level) So, I don't mind what graphic you use to help visualize your voiceover Dan, just don't show your face and let me continue imagining the Clark Kent doppleganger I imagine you are. And, as always, a big thank you for sharing your priceless knowledge.
Dan is really John Cleese; he's just using Vocal Bender to lower the pitch and alter the formant 😎
@@chrisk.6246 ⭐️⭐️⭐️⭐️⭐️
I was thinking as I watched this video that your logo is rad, extremely well done - It hadn't really registered just seeing it as a thumbnail on the channel. I like the minimalistic quality of the logo as visualizer and it seems to reinforce your brand identity. All that said it is, as always, the content that counts and your information and presentation is exceptional. Thank you.
I love your videos and how much solid clarity you bring to the table. The main reason I’m commenting though is to let you know that I personally think your new vocal visualizer is MUCH better than the old one. The animated waveform you used to use was actually really harsh on my eyes for some reason, and I always turned my screen’s brightness all the way down when it was on. This new one is pleasant, stylish, and cool
This was a really educational exercise! I was one of those people that thought that CZcams low-passes unless you get a 1080p stream or higher (or if you download stuff through a 3rd party service). Apparently CZcams is more clever than that.
I actually prefer the waveform thing compared to the new visualizer. Personally, I found the waveform more interesting to look at. But it wasn't perfect either. The waveform was a little too busy in my opinion. Maybe there is some middle ground between the two visualizers.
I'm fully with you. The new one isn't bad, but the waveform just looks far more interesting.
me too
Maybe it could release slower so it doesn't stay in black for long
It's a Dan aesthetic
Thanks Dan, just checked the stats in Safari 15.5 in macOS 12.4 and it seems to use Opus on all videos I tested, perhaps this is a non-issue anymore for the latest macOS.
A visualizer like that would usually be done in After Effects using the sound keys plugin. But then again, if it works, it works. And this works.
Takes so much processing power for it to not be extremely laggy and take forever to render
@@ProdDJD A spectrum like this would actually be really fast to render. By After Effects standards at least.
@@SkyyySi maybe, I don't know cause I haven't done this exact visualizer but I had a simple visualizer that just like 20 bands or something and it was extremelyyyyyy laggy on i7 core with 16 GB RAM and took hours to render, of course lengthened by the fact that you can only export in avi without using media encoder
I like the fancy waveform from "How Loud Should My Drums Be?" and yes - CZcams has quite a lot of file formats to serve, hehe.
Dan, you will always and forever seem to me the most honest youtuber I have had the pleasure of being subscribed to. So thankyou for that, and keep it up the fantastic content! I like the new visualiser a lot, and, contrary to some other comments, I like the fact that there is very little going on visa ve the background. I sometimes, perhaps often, watch your videos not looking directly at the screen, and so the minimalism is very nice in my peripheral and not too distracting! And even when looking straigh at it, the darkness matches with the silence and when you finally speak again it feels like sunshine on a rainy day :) all the best
The new visualizer is great & thanks for always pushing this amount of information out.
If you want to download the high quality opus audio file, JDownloader will do that just fine. Copy a video link and it'll show you all the different video and audio streams available to download (even the thumbnail as jpg and video description as txt).
It can do up to 20 downloads simultaneously, limit the download speed and do fancy stuff like shut down your computer when it finished downloading. Very cool tool!
is it free ?
Thx mate ! But a question. What to do with a opus file next ? I mean, you have to convert it, right ?
@@dekoto9817 depends on what you want to do with it, vlc plays it without any problems, your browser too
I quite liked the spectrogram visualization
I like this visualizer much more than the old one. I'm fine with the over the top renders that push after effects to it's limits, but this one fits your style of narration much more and it doesn't look jarring at all. I'm not visually sensitive (is that a term?) but I still like this simple visualizer much more.
Cheers for admitting that you weren't quite right in your previous video and boosting the correct information. If other youtubers handled things this way the platform would be in a much better place.
Bring that waveform back, it was way better !
re: the visualizer, you could do this directly in capture software like OBS; the "spectralizer" plugin will draw your shapes, then you can use filters to scale it, blur it, add color, and mask it with another image. the reaktor ensemble *is* pretty resourceful though and resourcefulness is probably one of the most admirable qualities i can imagine.
Would it allow me to split the signal into 5 bands, and tune RMS detection to get nice looking ballistics? Genuine question, I've not explored OBS much...
I came here for the post about the visualization and leave with some more knowledge; you have my full support even if you post a picture of a beach while you talk!
The visualization thingy is perfect, it really does match the no-bullshit style of your channel, IMO.
I like more the old visualizer. This visualizer in the dark of my room distrubs my eyes for the constant change of brightness
Loving the vocal graphic ;)
Great channel, it's good to keep learning (a lot) even after a 20 years carrier as sound engineer! Thank you!
What "Stats for nerds" won't tell you: Opus is resampled to 48 kHz, while AAC (mp4a) is resampled to 44.1 kHz. When analyzing sweeps, you might notice artifacts on the format with the different sampling rate than the one the original was uploaded with.
I noticed the new visualizer before you even mentioned it! It's cool, it somehow reminds me that I'm being talked to by a person named Dan rather than an oscilloscope.
Cool update Dan. And as my lecturers used to say, your graphical indicator of the vocal/audio performance, is probably ‘the minimum to sufficiently perform the task’…except I had no idea what the full reactor symbol looked like until you displayed it, because I am all iOS/iPadOS. Take care and carry on with your sonic dissections, eviscerations, and autopsies!
Tbh, I could live with a static image instead of some animation, because I don’t like blinking and flickering. Much more important, this was pleasant to listen to because there was no distracting background music.
I definitely like your new logo waveform thing more than your previous waveform visualizer which was very in-my-face. 😱
I personally do like this visualiser better than the previous one!
The new visualizer is simpler, and more precise. Love the videos. Keep up the good work.
Brilliant as always DW. I am very happy to learn the YT audio quality secrets because it has always been a mystery why some channels sound great on my JBL studio monitors, and others terrible.
Every video is now being encoded in opus now, except for a few low-view older videos, but low-view newer videos always get the opus codec regardless of view count (except for live streams - they still mainly get the mp4a (aac) codec for some reason)
Thanks for being open enough to accept & acknowledge correction.
I think the new display is cool, but I find it distracting with my mind trying to correlate what I'm seeing with what I'm hearing. A waveform is simple 1:1, so it almost fades into the background.
i think it generally goes into a better direction than your oscilloscope thingie, because it carries your identity through the logo. but i'm personally not a big fan of vertically fading in the image with louder sound, as that only results in being punished for a dynamic voice over. instead you could have the full logo shown at all times but only saturate it according to volume or maybe paint a circle around it that does something cool only when volume gets louder
I actually really like this idea too.
Always come with a new insight. Well done, Dan. Always love your videos.
Hey I think for the first time I really like the visualizer !
The D gets a lot more color that the W though, maybe a way to make it a little more homogenous ?
I can't unsee middle finger in this new visualiser plus two more fingers from other hand. And its sorta appropriate for this channel ;D
Love the new visualizer, more than the previous one!
Much prefer the waveform thingy. It eased my mind in some certain type of way I can't explain.
Speaking of youtube downloader, i know that "stealing" is the main concern so there are some countries that mandated those services to block any attempts at downloading copyrighted materials, but then again there are still rat holes used to circumvent that.
that artist dude knocked it out of the park with that logo. or a corner kick goal. or whatever you guys call it.
amazing logo.
I like the waveform More. It’s more personal, contains more information - feels more intimate. This new is cool, but too cool for school!
holy COW the new visualizer is great. I absolutely love how minimal and effective it is... and brand-reinforcing :) perfect!
THANKS ever so much Dan for the enlightment on all fronts.... I'd surely be liking the old Waveform over this clumsy animation thingy...🤣👍👍🥇
I hadn't noticed the stats for nerds before so, being a nerd, I'm delighted to have discovered it.
Opioid source here. Thanks for the extra clarity & info.
Thank you for video!
I think the best visualization for this channel:
The standard Windows XP wallpaper, where there is a slow-moving sun with the channel logo inside
I prefer the waveform. Love the channel.
I really liked the old wave form thingy.
I'd like to know more about CZcams artificially hobbling the Safari browser's audio. I use Safari and see opus(251) under stats.
Love the new visualizer!
I like the visualizer, its like my pc has turned into a worallbot, that has came to me to teach me sound engineering!
The new visualiser has a touch of Knight Rider era computer voices about it.. nice :-)
I prefer the waveform display. There's not enough to latch onto here and the visuals don't feel as connected to your voice as the waveform. Maybe if you'd increase the resolution of the audio analysis it'd work better? Though the visual design would change significantly.
True. Safari forces the AAC-LC codec on users that band limits at 16 kHz. Firefox gets one the opus codec and response up to 20.1 kHz according to the Spectragraph display. Now if we could just get bandcamp to stream up to 20 kHz. They do everything else so well. Sadly just 16 kHz at the moment.
Huge plus one for this visualizer. the other one was quite overwhelming (at least for me).
Thanks Dan! I like the new voice icon thingie. And stats for nerds is a nice tool. Thanks for the tip.
a simple and elegant visualizer, nice!
I think the visualizer is perfect. Please keep it!
Thanks a lot again I’ll test with another browser for sure
great that you always follow the evidence, like the new waveform visualiser thingy
I think a more appropriate visual would be every type of sonic display available. Spectrum analyser, VU meters, Stereo image graph, compressor duck amount display, waveform flyby, .. I'm sure there's more but that's all I can think of
I always knew that youtube does not degrade audio if you lower the video quality because I never heard any difference in audio quality while playing video at different resolutions. I did not know how but always was sure about it.
I really liked the old waveform, it is the genuine Dan Worrall brand
The new visualizer is nice. Looks simpler and allows me to focus more on the info
I vote for the waveform. Great channel!
You're a goat you're a legend you're the greatest of all time
I like the new visualization.
I think the negative space framing of the letters would be cool applied to any visualization correlated to your voice/narration.
Voice visualizer is much better than the other one. Appreciate that you took the time to offer a correction, thank you.
imo waveform was super distracting, so i really appreciate the change.
I like that a CZcams app I use lets you choose both video and audio streams manually if you want. I don't know why this feature isn't provided on the official clients, hidden or not. They have only progressively dumbed down the quality settings
I like more the waveform thingy, it has a interesting feeling
love the new visualizer! awesome info as usual.
On mobile with an older phone with crappy speakers if I watch a YT video on low quality the audio is poor too. At full volume and switching to 4K in the player the quality improves dramatically.
i like the waveform thing better because it always feels like im listening to some death robot imparting the law of proper mixing and requiring compliance. also i like that its filling the full width and imparts some nice information even tho not relevant.
You could probably rig something up to make your logo look like the incremental bands on a loudness meter.
I like a waveform visualizer more, but am fine with your choice.
I prefer this new visualization, the waveform was very distracting and I kept having to look away from it. Was too full screen and intense.
This is better, allows to still focus on your words while not getting bored with a black screen.
About the grafics. They look cool but I would flatten de frequency response so it looks flatter in the grafics and all the logo reveals at once instead of the left side only
1:32 “this would be a poor choice of platform for audio tutorials.” and right as you said this, I can hear birds in the background.
An unintentionally trolling moment nonetheless.
I actually like the old visualizer more. Kinda reminded me of getting a secret transmission from a hacker in the 2000s via WMP.
The new visualiser is FIRE!
It's fine, but i like the od one a bit better. You could switch between the two. I recommend the new one for this explaining kind of videos, and the old one when doing audio tutorials and/or rants, because it's more agressive. Good video as always, cheers
Nice job on the visualizer! The old looks better to me, but I can see how not everyone would like the sparkly waveform. But I turn off the light 💡 in my room to enjoy the lights on my synths or the glow of power tubes… xmas 🎄 every day!
Oh, you should probably be aware that CZcams apparently now silently enables a "stable volume" feature that applies (dynamics) compression to all videos. Very annoying and perhaps something to be aware of during compressor tutorials and the likes.
We're getting educated day by day thank you Dan , nice new visual btw but the wave form is better in my pov
Cool visualiser! Gives me a bit of a KITT vibe. And that's always good! :D
1:55 I like it. Thx for your video. I like your voice anyway and the gfx don´t matter to me. You can upload your videos pitch black and I will still watch (hear) them because of your voice and your educational content.
I have liked all visuals. The sound and information that comes out of you is what matters to me. You can put pimple popping for all I care I'll still watch. ..so no 320 kbps files huh lol
The waveform thingy was cooler. Felt more like I was being schooled in audio by The Hitchhiker's Guide to the Galaxy.
I like both visualizers
Sir, as a member of the fan base I have to speak out. The cacti at the campfire are not cutting it. We should return to the spooky menace of the wave a.s.a.p. and stick to the message: true expertise is an electrifying whacker.
I found the waveform fitting, because that’s what we’re concerned with. But tbh, that’s nerdy. I find the new one nice as well. Granted, it’s simplified, but then again it’s very stylish. And mixing music is about style. So if this is less migraine inducing, as implied by you in your community message, it’s a win-win!
The waveform is definitely a lot cooler. has a "Vibe"
The new visualizer is awesome!
New visualiser looks good Dan.
I liked the old waveform but the new one is more distinct and gives your videos a more personalised look
I prefer the waveform too. Also, you could use some great visual tool using after effects. Much more in-depth and easy to implement than traktor in a youtube video
