Late to the game here... but, when considering VFR, should the degrees still remain at 180d? I.e, say I'm shooting 1080p@24, but am shooting at 120fps in Variable Frame Rate. What should the degrees be?
Best explanation of SS, frame-rate and angle I've ever watched - NOW I actually understand! Just got a GH5 and got a lot of other info and tips from your other videos.. Thank you!
Absolutely best video on the subject. Too many other youtubers think they know it all with their instructional vids. Your presentations are well made and very informative. 👍🏻👍🏻👍🏻👍🏻👍🏻
This is EXTREMELY helpful. Please note that synchro scan is an incredibly useful feature and not found on most DSLR cameras. In this video you emphasized non-LED light sources but dimmed LED lighting that aren’t designed for video shooting is originally why I sought out synchro scan. Slowing down to a 172 degree shutter angle can compensate for banding. This also makes it easy to shoot video in countries that have a different power cycle then the default on your camera (NTSC or PAL) and with mixed ambient/environmental lighting where flicker or banding can occur. The G9 not having synchro scan (as you’ve mentioned in your video detailing the G9) is why I returned it and opted for a GH5s as my secondary camera (GH5 is my primary).
Holy crap - you just explained why that scene from gladiator is stuck in my mind for eternity. I knew it was “high speed” but didn’t really understand the fundamentals. You’re a great explainer.
Explained in a clear and precise way, without any of the useless and wild cut scenes found in other peoples content. You've got a great way about you, and a new subscriber. Cheers!
In film nomenclature is borrowed from a variety of different sources: math, science, art, psychology, etc. Some are just made up names and phrases that stuck. Others updated from historic disciplines like Best boy. Still others come from the name of the creator. I'm going to go with math until I'm told otherwise.
Why is it that I always find the best explanation last? Maybe I started at the wrong end? Anyway, best real-world "English" explanation yet. No technobabble or jargon that leaves the viewer as bewildered at the end of the video as he was in the beginning. You explained this concept better than they did in film school. Well done PhotoJoseph.
Wow thank you, I really appreciate that. You might appreciate this video next, then. In this one I explore why we get flicker from certain lights and how to avoid it, from a very technical perspective. It’s just math! ;-) czcams.com/video/0kAuDuV9K9U/video.html
This is helpful for those looking at this from a photography background to see how theses settings specifically affect video like getting a sort of jarring shaky movement with a fast shutter or motion blur at slower speeds. It still seems funny to me that we use these analogues of either photography or cinematography, when we have no film to have ISO ratings, or grain size, and we don't have any shutters or spinning disks, and nothing is getting mastered to film. It's all emulated. Our cameras spend a good amount of processing power just so we can be more comfortable with using an old framework to understand them as as if they where antiquated devices. It seems if we just had something like a frame rate and a percent duty cycle setting, it would make just as much sense from what we are achieving as long as we know what the adjustment effects (which is essentially the same as the shutter angle analogy). We could also be adjusting different ways that we averaged the light data that we get inside of that frame, we're taking advantage of the actual characteristics of the image sensor and the processing algorithm. Anyway, it seems like the best you can do is try to learn from the best, what to look for and how to create it, and understand the underlying principles of why that worked for film and how to achieve it digitally.
Hah you’re not wrong! All these analog terms are definitely odd in a digital world. On higher-end LUMIX cameras you can actually set the ISO to gain, which is what’s actually happening. Shutter speed in fractions of a second is accurate whereas as angle is not, BUT using angle does let us do things like set an optimum shutter speed for desirable motion blur (i.e. 180° or ½ the available time as dictated by framerate) and leave it there as we change framerate for things like slow motion.
Have to comment here. 9.30 in you mention the scen in Gladiator, Blain Brown have explained how this was filmed. Qoute: Gladiator during the battle scene that begins the film. As the battle just after dawn, the shots are the normal frame rate of 24 fps, but as the sun goes down, shots are done at 6 fps. This gives a blurred look that effectively gives the feeling of fatigue and blurred vision that would result from an entire day of hand-to-hand fighting. In the DVD commentary, director Ridley Scott reveals that the reason this was done was that they were running out of light. By shooting at 6 fps, the shutter speed becomes 1/12th of a second, which gives a bonus of an additional two stops of exposure. In this case, the effect has a double bonus. Using slow frame rates for extra exposure can easily be used when the subject is static or has no identifiable that would reveal that the camera was running off-speed. End qoute.
Good Job, i just sub your Channel. Anyway, most importat thing about angle is: motion perception and motion blur. At 90° you'll have a very quick image perception, but in 180° we can see a natural motion. Human kind is a complex machine. Cheers from Italy.
That's not really accurate since your terminology ("quick image perception") doesn't really describe the phenomenon. One of the primary reasons math is so tough: the abstracts. We learn by building on things we already know. But how do you explain a concept that doesn't relate to anything you've experienced previously? I understand what you're saying, but that's only because I already know what you're talking about. No denigration intended. It just reminded me of something from when I was growing up.
G'Day Joseph, I am truly amazed at how you provide such good information to all who are lucky enough to find you, absolutely free. You are such an inspiration with a tonne of energy taboot. I like your presentation style (although you could slow down just a little at times). I have been watching your (and others) video/tutorials for the past year or so now to understand how affiliate marketing works and I will support you by way of purchasing items I may need in the future through the links you provide. I am a budding film maker at 56 that has only recently discovered the "JOY" of droning with my mighty Mavic Pro and all of it's fantastic flying & filming features. Being a newbie, there is sooooo much to learn about photography, filming, editing, audio and the list goes on. Good folk such as yourself have helped point me in the right direction. I am so inspired and keen to fire-up my own CZcams channel...(watch this space), I am currently fine tuning my pilot & filming skills and slowly adding the equipment to my kit. It is important to me to provide quality content before pressing the go button on CZcams. Also being on a limited budget has its challenges but I do believe bit by bit I will get there. I am fortunate to have a iPhone 7+ and the Mavic Pro drone to film with and a reasonable low-cost editing program "Luma Fusion" to help me produce my visual eye-candy. Well I think I have rambled on enough for now and bid you a goodnight. Until the next time... Cheers from Spike (Central Wheatbelt - Western Australia)
Thank you Spike! Yeah, I go fast… but that's me ;-) Good luck and enjoy LumaFusion. Have you seen my videos on that? Some are a bit old, but I did a fun vlog one around their new Gnarbox integration. czcams.com/video/aVwFm4STIkM/video.html
Ditto on the thanks for a very informative video - suddenly the whole shutter angle thing becomes clear. Also ditto on the request to speak a little slower! :-D
Tja, people that understood things, can explain them simple. Thats how it is. Thanks for sharing your clear view on this topic. I missed one thing though: What If the available light in the scene changes? It´s probably not the aperture that is constantly adopting to the light, right (depth of field would constantly change). How do we prevent the image from getting darker or brighter all the time? And I thought we keep the framerate constant too, because 24 is cinematic, not 102 or 321,5. Or do we accept the recording getting darker and brighter?
Three parts to the exposure triangle - shutter speed (or angle), aperture, and ISO. If one changes, so must another. Your reference to 24 being "cinematic" is frameRATE, not shutter speed. And has nothing to do with exposure. As light changes, you can adjust any of the three. Usually you don't want to adjust aperture because as you said, depth of field changes. Usually you don't want to change shutter speed/angle, because that can change the look of motion. If you change the ISO a little no one will notice, but if you change it a lot you will introduce or remove noise. So the real solution is to control the light coming into the camera with a variable ND filter! I have several videos on ND and VND filters: www.youtube.com/@photojoseph/search?query=variable%20ND
Very useful video thank you! I presume since the shutter angle is fixed at 180 degrees for video we can no longer rely on the shutter to correct exposure and have to adjust other settings to control the light?
That is correct. In a variable light situation, your best friend is the variable ND filter. If ISO changes, then dynamic range and noise can change (this is, IMHO, the _best_ component to have change automatically if you’re shooting semi-auto or using a camera setting to adjust exposure). If shutter speed/angle changes, depending on the motion in the scene, that can change the look of the shot (smooth vs jittery movement). If the aperture changes, then the depth of field changes. Plus unless you have a lens with stepless aperture, you’ll see the jumps from stop to stop. So, best method is to lock all three settings and control the light reaching the sensor with a variable ND!
@@photojoseph The best video on this matter that i found was: "Motion Blur, Shutter Speed, & 180° Shutter Angle // TESTING the RULES! " and the idea is that with less motion you expect to get less blur, so if you slow down 50fps, you'd need to stick to 180 rule. If you're not, it's more natural to see a full 360 (1/50th) shutter. Complex issue :)
V clear and useful but I always understood that 180 shutter in film cameras was 180 degrees because the shutter needed to be closed while the film pulled down. Puzzling.
Same idea. The difference is T stops measure ACTUAL light transmission (T), not calculated based on focal length (F). So three lenses from the same manufacturer at T4 will all be identical exposures. Three lenses at f/4 may not.
Great vid! Though, am I right in thinking that if we use synchro scan to heavily we will affect the motion of the image? Say we were shooting 25fps at 180d (1/50) but need to adjust to 210d to fix flicker, this would effectively be the same as adjusting to shutter speed to 1/60 (1/58)? Is there a rule of thumb this?
Hi Joseph, thanks for the video, very helpful! I have a different question though...Would you mind sharing your set-up for PIP and how you source all your different angles in this video? I film a lot of depositions and Im trying to find a seamless way of filming the witness and at the same time bring up a separate image (exhibit) via an elmo. Thanks for your time. Sincerely, Johnny
I’ve actually done several videos on my live stream setup, and I’m sorry to say that it’s much more complex than it appears! Watch this video first czcams.com/video/aL1gV3yJvCM/video.html and from there, here’s a three-part very detailed look at my setup czcams.com/play/PLRe8DcOhgslp8kbjeTNG0S6KwR6_u_dyt.html (although it’s over a year old now and some details have changed).
that's an excellent question. I will often to go 360d when shooting slowmo. Say you're shooting at 120fps; at a 180d shutter that's a 1/240s shutter speed. That's fast. Even at a 360d shutter it's still 1/120th. Either way your frames are going to be pretty motion-blur-less, so the answer is more about how much light you have than the look. Unless your subject is really fast, it'll be hard to tell the difference.
PhotoJoseph oooo! I did not realize there was another update. Im too busy enjoying shooting with my GH5 😁great explination about angle vs shutter speed btw 👍🏼
I have seen this turtorial several times and I understand the sync and thee moore preciseness but still I really don't get why/where you loose aprox. 1 step of light. Should'nt it be the same at 25 fps to 50 of a sec. in exposure as 180 deg.= half the time ? In what manner isn't that equal with half the exposure as the 180 degrees to 360 ? Should'nt it in fact (but not possible) the exposure need to be 100 of a sec for 25 fps ? Where do we loose time for enaugh light to the sensor ?
Thanks for watching! Ok… 180d shutter means it’s exposing for HALF of the TIME of that frame’s existence, right? If you’re shooting 25fps, then each frame occupies 1/25 of a second. Half of that is 1/50, so your exposure is 1/50 second. If you’re shooting 50fps, then each frame occupies 1/50 of a second, so then a 180d shutter is a 1/100s exposure - again, half of the existence of that frame.
@@photojoseph About so .... I thaught but you have "clearing up my mind" so I ubderstand it as well. 😅 Huge thanks ! 😘 Its a litle bit harder to get it when you not are a "native" to the language.
If you had to guess (or if you know the answer), what would be the maximum difference in the standard FPS x 2 = SS model before audio becomes noticeably unsynced to the human eye during playback?
Well, eventually the video will playback with either a ton of motion blur or staccato and stop-motion-y. If you were to interview someone, wouldn’t pushing the shutter to either of these extremes make the audio not line up with the persons mouth?
Thanks for the video, I have changed to shutter angle but can not get back to SEC/ISO, I am in video mode, I can only change to either angle/ISO or SEC/db, if I change to SEC/ISO it will not do it, what I am doing wrong please?
Hello. I shoot with a gh4 and there is lagging images when i shoot movement shots. I have also noticed in this video when you move your hands they are not (Sharp/smooth) how can that be corrected. Please help
Thank you, very valuable information for me. My question is - how to find the closest to 180 degree shutter angle value, if my camera allows me to control only EV and ISO?? There is got to be a way to estimate these values for 30fps and 60fps. Thanks
Yes, ideally 180 degree angle all the time even at whatever frame rate you are shooting at. Unless you encounter flickering from lcd/tv/fluorescent etc, then use synchro scan to micro-adjust the degree accordingly.
Does the shutter angle affect the responsiveness or speed of the AFC focus in the GH5? I shot an indoor gig of a 6-piece band on a large stage last week with lots of new custom settings, one of which being 240deg. Even filming with 3x GH5 cameras I had to do a lot of panning around and zooming to get close-ups on each person, and the AFC performance was very slow.
Hm, no… frameRATE can affect AF though. IIRC the GH5 samples 60 times per second so 60FPS is best AF performance, 30fps would be slightly less (although probably not recognizable), but 24 may be slower. I think that’s right; it’s been a while since I looked at those numbers.
@@photojoseph I'm UK so was at 25fps. I don't shoot gigs at 50fps, there's not usually enough light. If it was a pop show with a dancing singer under a spotlight; yes I would
Thanks for such a good explanation, I often wondered what it meant. I don't really do video as I don't fully understand it or really need it but I sometimes push the red button just to grab a moving scene or something. If I do this if and set the camera (G85) to iAuto will the optimum video setting be selected for me? I am just looking for a quick and dirty video that will look OK for a travel memory or adding to a slide show. Most of the things I would lake are less than 60 seconds. So far I have not used snap video or what ever it is called.
Yeah just push the red button :-) For what you’re shooting that’ll be just fine and you don’t need to worry about shutter angle or even speed too much. I wouldn’t bother with the snap mode either. Just shoot stills however you’re comfortable and when you want video, push the red button!
Thanks for a really good explain for this. The benefit with the CZcams and guys like you. If you wonder how thinks works out just search and find the answer. You are a really “to go” at the subscribe button :) again thanks for good and exactly explanation.
OMG this would be very informative but I can't get over how fast your speak. It's very distracting. Sorry don't mean to be negative. Good video but hard to follow because of this.

@@photojoseph The best video on this matter that i found was: "Motion Blur, Shutter Speed, & 180° Shutter Angle // TESTING the RULES!
" and the idea is that with less motion you expect to get less blur, so if you slow down 50fps, you'd need to stick to 180 rule. If you're not, it's more natural to see a full 360 (1/50th) shutter. Complex issue :)
That it is! Since you’re enjoying my videos, if you like the complex topics, you’ll enjoy this one: czcams.com/video/0kAuDuV9K9U/video.html
Great help. Thank you.
V clear and useful but I always understood that 180 shutter in film cameras was 180 degrees because the shutter needed to be closed while the film pulled down. Puzzling.
Would you recommend shooting on Auto, manual or the other options for exposure mode?
Thank you so much 🙏
Sir
Any video on F stops vs T stops
Same idea. The difference is T stops measure ACTUAL light transmission (T), not calculated based on focal length (F). So three lenses from the same manufacturer at T4 will all be identical exposures. Three lenses at f/4 may not.
Great vid! Though, am I right in thinking that if we use synchro scan to heavily we will affect the motion of the image? Say we were shooting 25fps at 180d (1/50) but need to adjust to 210d to fix flicker, this would effectively be the same as adjusting to shutter speed to 1/60 (1/58)? Is there a rule of thumb this?
The only rule is to eliminate flicker (because that’s hideous), then keep your shutter angle as close to 180d as possible for “natural” motion.
I have a GH4, and have the 1/50 set for my shutter? Should I keep that or change to the 180D or it won’t matter I’m filming a film
I subscribed your chanel for this video, first time learn about that. Hope this helps for my Gh5 🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥🔥
Awesome! Also watch this one: czcams.com/video/0kAuDuV9K9U/video.html
Hi Joseph, thanks for the video, very helpful! I have a different question though...Would you mind sharing your set-up for PIP and how you source all your different angles in this video?
I film a lot of depositions and Im trying to find a seamless way of filming the witness and at the same time bring up a separate image (exhibit) via an elmo. Thanks for your time.
Sincerely,
Johnny
I’ve actually done several videos on my live stream setup, and I’m sorry to say that it’s much more complex than it appears! Watch this video first czcams.com/video/aL1gV3yJvCM/video.html and from there, here’s a three-part very detailed look at my setup czcams.com/play/PLRe8DcOhgslp8kbjeTNG0S6KwR6_u_dyt.html (although it’s over a year old now and some details have changed).
Great thank you
Thanks. If you want to do slow mo, do you leave the setting at 180?
that's an excellent question. I will often to go 360d when shooting slowmo. Say you're shooting at 120fps; at a 180d shutter that's a 1/240s shutter speed. That's fast. Even at a 360d shutter it's still 1/120th. Either way your frames are going to be pretty motion-blur-less, so the answer is more about how much light you have than the look. Unless your subject is really fast, it'll be hard to tell the difference.
Also worth mentioning that the autofocus works better from 179 degrees and lower.
Sure… but this video wasn't about autofocus ;-) And that will change with the update on Wednesday, bringing that performance to 180d where it belongs!
PhotoJoseph oooo! I did not realize there was another update. Im too busy enjoying shooting with my GH5 😁great explination about angle vs shutter speed btw 👍🏼
I have seen this turtorial several times and I understand the sync and thee moore preciseness but still I really don't get why/where you loose aprox. 1 step of light. Should'nt it be the same at 25 fps to 50 of a sec. in exposure as 180 deg.= half the time ? In what manner isn't that equal with half the exposure as the 180 degrees to 360 ? Should'nt it in fact (but not possible) the exposure need to be 100 of a sec for 25 fps ? Where do we loose time for enaugh light to the sensor ?
Thanks for watching! Ok… 180d shutter means it’s exposing for HALF of the TIME of that frame’s existence, right? If you’re shooting 25fps, then each frame occupies 1/25 of a second. Half of that is 1/50, so your exposure is 1/50 second. If you’re shooting 50fps, then each frame occupies 1/50 of a second, so then a 180d shutter is a 1/100s exposure - again, half of the existence of that frame.
@@photojoseph About so .... I thaught but you have "clearing up my mind" so I ubderstand it as well. 😅 Huge thanks ! 😘 Its a litle bit harder to get it when you not are a "native" to the language.
Fair! And glad to help :-)
Thanks for the vídeo
If you had to guess (or if you know the answer), what would be the maximum difference in the standard FPS x 2 = SS model before audio becomes noticeably unsynced to the human eye during playback?
I don’t understand the question. Shutter speed has nothing to do with audio sync.
Well, eventually the video will playback with either a ton of motion blur or staccato and stop-motion-y. If you were to interview someone, wouldn’t pushing the shutter to either of these extremes make the audio not line up with the persons mouth?
@@tomcashman6203 no… but please explain the situation, with numbers.
Hello! I can set my G9 to shutter angle...
I assume that was a question not a statement… and no, the G9 does not have shutter angle, sorry
Thanks for the video, I have changed to shutter angle but can not get back to SEC/ISO, I am in video mode, I can only change to either angle/ISO or SEC/db, if I change to SEC/ISO it will not do it, what I am doing wrong please?
Hello. I shoot with a gh4 and there is lagging images when i shoot movement shots. I have also noticed in this video when you move your hands they are not (Sharp/smooth) how can that be corrected. Please help
Sounds like you need to learn all about shutter speed in video! I have a video just for you my friend… czcams.com/video/m_fS-noZlf4/video.html
Thank you, very valuable information for me. My question is - how to find the closest to 180 degree shutter angle value, if my camera allows me to control only EV and ISO?? There is got to be a way to estimate these values for 30fps and 60fps. Thanks
double your frame rate. At 30fps, 180d shutter is 1/60s
@@photojoseph Thank you! Tried to do so, there is no option to switch shutter speed... only EV compensation and ISO
you have to be in manual exposure mode
Waaaooo thanks brother am not the same now
Can I use 180 anlgle for all the frame rate I mean if I'm shooting 24p my angle will be 180 and if I'm shooting 60 it will be 180 also? Thank you
Yes, ideally 180 degree angle all the time even at whatever frame rate you are shooting at. Unless you encounter flickering from lcd/tv/fluorescent etc, then use synchro scan to micro-adjust the degree accordingly.
@@my3k1z That's provide you're looking for the standard "filmic" look.
Does the shutter angle affect the responsiveness or speed of the AFC focus in the GH5?
I shot an indoor gig of a 6-piece band on a large stage last week with lots of new custom settings, one of which being 240deg. Even filming with 3x GH5 cameras I had to do a lot of panning around and zooming to get close-ups on each person, and the AFC performance was very slow.
Hm, no… frameRATE can affect AF though. IIRC the GH5 samples 60 times per second so 60FPS is best AF performance, 30fps would be slightly less (although probably not recognizable), but 24 may be slower. I think that’s right; it’s been a while since I looked at those numbers.
@@photojoseph I'm UK so was at 25fps. I don't shoot gigs at 50fps, there's not usually enough light. If it was a pop show with a dancing singer under a spotlight; yes I would
Thanks for such a good explanation, I often wondered what it meant.
I don't really do video as I don't fully understand it or really need it but I sometimes push the red button just to grab a moving scene or something.
If I do this if and set the camera (G85) to iAuto will the optimum video setting be selected for me?
I am just looking for a quick and dirty video that will look OK for a travel memory or adding to a slide show. Most of the things I would lake are less than 60 seconds. So far I have not used snap video or what ever it is called.
Yeah just push the red button :-) For what you’re shooting that’ll be just fine and you don’t need to worry about shutter angle or even speed too much. I wouldn’t bother with the snap mode either. Just shoot stills however you’re comfortable and when you want video, push the red button!
Sir
How much time a rotor shutter takes to comple a single 360 Deg. rotation?
Is it 1 Second?
You have misunderstood how shutter angle works. Please watch the video again.
@24 fps the least it would be is 1/24
Thanks for a really good explain for this. The benefit with the CZcams and guys like you. If you wonder how thinks works out just search and find the answer. You are a really “to go” at the subscribe button :) again thanks for good and exactly explanation.
glad it was helpful!
👌🏼👏🏼👏🏼👏🏼👏🏼👏🏼👏🏼
thank you! Funny, this video is suddenly getting views… thanks for watching!
Ah. 180 degree shutter automatically does the math for you.
Basically, yep.
Slow down !! Less coffe perhaps ! ;-)
Couldnt agree more.
OMG this would be very informative but I can't get over how fast your speak. It's very distracting. Sorry don't mean to be negative. Good video but hard to follow because of this.
You can slow down the youtube video to 0.75 speed
Thanks for this great video.
