Yo at 8:05, you have 60p footage with a 1/50th s shutter speed. With a shutter angle greater than 360 degrees, wouldn't the camera actually be recording at a lower framerate? If the camera actually opted to actually record at 30p 1/50, then naturally that would look similar to the 24p 1/50 footage. Or is this mislabeled and the shutter should be 1/60 of a second?

@geraldundone 4 года назад

It's possible on some cameras to do this. All that appears to happen is some frames just repeat. So it's a bit jerkier, but the motion blur is the same.

@thatcherfreeman 4 года назад

@@geraldundone I mean we can't tell when watching the video because it's a 24p project, but is that clip somehow shot on a camera where it isn't jerky at 60p 1/50? I assume you shot it on the a7s3 right?

@@thatcherfreeman Initially I was bother by this too as it's not physically possible. But then I remembered that years ago when I used to have a d5300 DSLR I was able to shoot 24fps at super low shutter speed.

Thanks for having me chime in Gerald! It was super interesting to try to erase the obvious bias that I have and actually choose which one looked the most NATURAL to me. And its also interesting to note that the one that looked the most NATURAL isn't the one I would prefer to shoot at because of the "soap opera" effect. I always felt like the soap opera thing made me feel like I was standing beside the camera op. This obviously makes it feel more real but it's also the reason I don't like it as much.

@Pfagnan 3 года назад

I have always shot everything at 60 fps but with the 180degree rule because I detest motion blur when panning and moving around, it is very distracting. This way my videos having twice the information and frames are crisp and sharp even when there is a lot of movement in the scene. I can also slo-mo or speed ramp things. I will now try at the 1/60 shutter to see if that stays sharp while reducing the so-called soap-opera effect. 24p is old school and technology has changed enormously over the years. Cinematic my ass....

@AJ-on-youtube 8 месяцев назад

@@Pfagnan different use cases. News, sports, live TV spots, vacation footage, are all meant to look like real life, and the realistic look of 60p (or even 30i, but not so much 30p) is desirable for those situations, but if you want your production to look like a movie, those frame rates tend to spoil the "movie" look. You can avoid excessive motion blur and stuttering at those lower frame rates by using wider focal lengths and moving your camera more slowly.

Ya I have changed things and use mainly 30p now. RU-vid loves this 4k frame rate

Great video Gerald, Congrats! In wedding we use 50p all the time with 1/50 shutter (in 25p timeline editing) because we don't know what moment should we put in a slow mo in editing, but we want to the normal speed record sections have a natural blur. We know the slow-mo sections have to much blur, but is a much better compromise than the normal speed sections have not enough motion blur. Moreover in that way the 50p record in 25p timeline with 1/50 shutter in normal speed (droping every second frame) looks excatly the same as a 25p with 1/50 shutter record, but the whole wedding is slow-mo capable if you need it.

A key detail is if you're trying to stabilise footage, you need a faster exposure so all frames are sharper. Otherwise you end up with a weird 'blur' effect on the object that has been stabilised. It looks a bit like it is vibrating from bass as you get motion blur on something that isn't moving any more.

@ScottBalkum 4 года назад

Soap opera can be easily defined as anything that appears realistic to our eyes. Our eyes see approximately at 30fps, but it is variable. When we see 30fps video, our eyes detect it as closer to reality. 60fps is even closer to reality. 24fps simplly looks “cinematic” because it doesn’t look normal to our eyes. We have since adjusted our brains to understand that 24fps feels “not-normal” and we can easily step out of reality to view it. We aren’t confused in our brains that we are looking out a window at life but rather, we are viewing something out of reality. Motion blur is simply another version of reality vs not reality. Our vision has a similar motion blur to 180 degree rule. So we see that as normal. It just so happens that 24fps is abnormal and 180 degree shutter is normal. The combo is remembered as cinematic. In the end, use shutter speed to tell your story. Increase motion blur to take our brains out of normal and decrease to bring it closer to reality, but you can also take it back to abnormal with no/minimal motion blur. Gerald, you did a great job showing it with the spinning line. Perfect.

Also, when doing screen captures in video .... it seems something hard to achieve when you are recording a video and nothing seems really in sync

@Quetzalcoatl0 4 года назад

Yep, 95% of devices are still on 60hz displays so 24p needs 3/2 pull down ratio to fit into 60hz, this adds jerkiness on smooth panning shots. I don't get it why RU-vidrs cry about shooting videos in 24p especially when it's gonna be played 100% on a RU-vid video player that will NOT change the frequency of the screen to match it or at least make it double like it do with my monitor. I switch it to 48hz. 24p is slowly getting into religions territory. Also if you are just talking and waving hands, it doesn't matter if its 24p or 30p. I bet 90% of the people watching won't even notice.

@jefparker 3 года назад

@@Quetzalcoatl0, exactly. Frame one shows twice, frame two shows twice, frame three shows THREE times, etc. 24fps on 60Hz is a mess. RU-vidrs are romanticizing jerkiness, not a more filmic look. Fortunately 24fps gets less messy on 120Hz and higher monitors.

@EposVox 4 года назад

I found this video really fascinating, but am left yet unconvinced that 24fps is a reasonable choice at all. I saw zero noticeable difference in 24 vs 30 for blur, or in general, and the frame pacing difference of fitting a 24hz video into my 60hz display (which the vast majority of people are using) I still see separation of the spin even in 24 and 1/50. I hate this discussion because I feel like as a video nerd I should be seeing and valuing whatever difference there is and I've never once in my life been convinced 24 is "more cinematic" or smoother, meanwhile there's tons of judder/pacing issues upsampling it to 60hz displays.

@hoojamaflicks 4 года назад

I have to agree. never have liked 24p for exactly the same reasons. on a 60hz screen 60p at close to 60fps looks most natural to my eyes.

@thatcherfreeman 4 года назад

You'll see separation in the spin whenever the shutter angle is less than 360 degrees. I think with 24p the convention of having a 180 degree shutter largely comes from a balance between a short shutter speed where things would look very staccato and a long shutter speed where slow moving subjects are difficult to track because of their blur.

@geraldundone 4 года назад

24p is definitely inferior in most ways save for maybe cost/space efficiency, but I'm just so used to it. We say it's filmic, because it is. I suppose the question that should be asked is: Is filmic a good thing? I guess if you're trying to emulate a look then it makes sense, but I'd need a good year of only seeing 30p content everywhere to erase the 24p conditioning. 😜

A key thing not really discussed is the camera and subject's relative motion to each other. So for instance, I shoot interiors videos. With slow camera movements and a static subject (a room), 360 degree shutter can absolutely be used even for slow-mo delivery, and I often do use it to keep from having to crank ISO. If I were shooting sports, that would be different I can see a pretty strong use case for over cranking there. IMO the 180 degree rule is a good guideline for those just learning and a good general fallback in situations where literally anything would work, but it certainly isn't appropriate for every situation.

@colinjudge1261 4 года назад

I think Jordan Drake’s comment on using 60p at 1/60th was the key takeaway here. With shutter speed determining blur and frame rate determining how we actually perceive that blur, the choice then comes down to the filmmaker. There’s no right or wrong answer, there’s simply “What are you trying to achieve?”. It’s maybe a little bit like a photographer asking what’s the right shutter speed and aperture combination? You can tell them the Sunny 16 Rule, or F8 and Be There... but they’re just guidelines for adequate exposure or focus. If you want to master your craft, then understand the effects of each variable, and make a considered choice. Also, be willing to have fun, take risks and experiment!

@TMAX500WHITEMAX 10 месяцев назад

Motion blur does not exist in reality. Only cameras record it due to the principle, the human eye works completely differently and that's why you can't see it. The human eye never expects motion blur. That is complete bullshit. The human eye has a problem with fast movement and since it only distinguishes between important and unimportant, it is also not possible to consciously perceive unimportant things. Because as soon as it becomes important, it can be recognized sharply again. The 180 degree shutter rule was never the reason to create motion blur, this rule only had something to do with exposure metering. That's why the 180 degree shutter rule is complete nonsense today. The soap opera effect also has nothing to do with high frame rates or fast shutter speeds. This was old video technology and is caused by intermediate image calculation during film playback and describes a clear separation of moving actors and objects from the background due to system-related image errors in the intermediate image calculation. I have always consistently ignored this stupid rule and have always filmed at high frame rates and the fastest shutter speeds. This means high image quality and very smooth motion. Blurred frames always look like shit in motion. Poor quality over the length of the film. And that's just because of something stupid like conservative backwardness and stupid habit.

@KDHildreth 4 года назад

How did you capture the motion blur at 4:54 did you take stills instead of video? I know on the Sony A6xxx cameras you cannot get any more motion blur than frame rate = shutter (i.e 25fps = 1/25 shutter), if you under crank the shutter the camera just duplicates frames and no more blur is captured/recorded.

I've been using the 1/60 at 60p trick for years to make sped-up-in-post footage look natural. I can't believe I never thought to take the idea forward into slowed-down high framerate footage. D'oh!

Regarding the latest comments on my original Video I would add: The 180° rule referring also to the publishing frame rate. When it was developed movies were published at lower frame rates. - I still think it's important to rethink the concept when publishing at higher frame rates (like those 48fps movies) or if the slow motion you're creating doesn't go directly to 24fps, ... like you filmed that 240fps segment, but then that's too slow and you decide to divide the speed by 5 instead of 10 ... But than again ... why would you have filmed it at 240fps? Because you can? Or because the rule said: For Slow Motion use the highest fps you have! And after all: this had been settled so much earlier already: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-8ThDAmTm5Ws.html

Personally, I find 24p and to a much lesser degree 30p to look very unnatural. Choppy and distracting. I’m so used to the more natural look of 60p that if I enlarge a 24p video to full screen my brain is constantly telling me my video card or display is broken. Although it’s useful for “cinematically” hiding how fake movies actually are (see The Hobbit in HFR for the dangers of not using it on a big budget film), for anything else I feel it’s like riding a horse and carriage down a freeway. Again, just my personal feeling 🤓😏

@gaboaaa23 2 года назад

Hi, is it neccesary to follow the 180 rule? Where you set the shutter to double the size of the framerate. I want to shoot in 4k 60fps. Is it a huge difference in smoohtness? Because if i use the rule, i have to use ND filters wich is anoying on a cloudy day where the sun changes every 5 minutes. So do you shoot with 1:120 shutter speed or just film with chanfging shutter speed?

@Pfagnan 2 года назад

I shoot EVERYTHING in 60fps and then EDIT in a 60fps. People it’s 2022 so do we really need to be shooting and editing at only 24fps because that’s what they had available in the 1930´s and 40 ‘s with their old metallic mechanical shutters? RU-vidrs insist on this traditional way of doing things. We now have the technology to do much better. 24fps has too much choppiness and motion-blur as there are too few frames for the processor to write to. Especially when panning or scenes with lots of motion you know what I’m talking about! I have done many tests with this and that is why I shoot at 60fps and EDIT at 60fps that way your audio is still in sync (everything is real-time not slo-mo) but you have more frames to capture crisp, clear, sharp detail and movement in the scene and especially when you pan!! You still get some nice motion blur. A little motion-blur is natural but fuzzy pixels and choppy motion when panning drives me crazy. I usually try to stick with the 180 degree rule for shutter. I will try using it at 1-60 sec shutter as Gerald suggests to minimized the soap opera effect SHOOTING AT 60P is so immersive. (Edit in 60 p though) Try it you’ll see….

When I shoot I move slowly. TBH I do not see a difference in 25fps and 50fps. The chop, a large gap between the moving object's start and finish position can be filled with motion blur. The 180 deg rule makes sure of that. Low fps like 24, 25, 30 are really more for workflow efficiency since they are faster to work with which can be real a saving if you do editing all day every day. I normally do 50fps shoot and 50fps edit for real time just because I don't need the best workflow efficiency and I can choose 25fps edit if I need slowmo. The worst thing someone can do is low fps shooting at high shutter speed (e.g. 25fps 1/100) for a very fast moving object or fast camera rotation. It will be choppy to varied degrees depending on the situation. I am not sure how many people end up doing that but the 180 shutter rule should make people steer well clear of that choppy zone. I did get into the choppy zone accidentally with 25 fps when shooting a fast moving dancer indoor with from what I can remember 1/125 shutter speed. Even that 72 deg shutter angle was still usable for the motion unless you really concentrate on the chop. So you cannot just flat out say it is 2022 and 60fps is a no brainer. The reality of fps choice is a more calculated one for the knowledgeable shooters and mostly subjective one for the uninformed shooters.

@radiozelaza 4 года назад

BTW, there's another case. When filming in 60p (for intended 60p viewing), do we need to follow the rule (which would involve the use of ND filters outdoors)? With such a high frame rate, the choppiness of using very fast shutter speeds should not be that visible - at least for the casual viewer. That would be an interesting experiment, an A-B test to check whether the footage shot in violation of the 180 deg rule induces any ill-feeling...

@stevenpam 4 года назад

Thanks, Gerald! Those of us with a stills background, and therefore no superstitious attachment to the 180° rule, suspected this all along. Understanding shutter speed from the perspective of video *and* stills - and using evidence, rather than just tradition - is definitely worthwhile to better inform creative decisions.

I am more confused after watching this that before.

@sandboxaperture7013 3 года назад

This answers my question. I always wondered that if you shot everything at 120 with a 1/250 shutter speed, will you get the best of both worlds; being able to slow down your video to ultra slow mo while still being able to maintain natural looking motion blur in a 24fps timeline by simply dropping frames. The answer seems to be no. Shutter speed for 120 would need to be adjusted regardless of it being dropped in a 24fps timeline. Thank you Gerald Undone.

@动漫区漫哥 2 года назад

Hello dude,shoot at 60fps 1/100，does the motion blur looks natural？

@thomasjmcclure 4 года назад

Hey Gerald picked up a bmpcc 6k recently and love it, but have seen some problems with IR pollution with ND filters. any chance we could see a video on good IR cut filters? the problems with IR pollution etc. there aren't many good vids online atm.

@snwmrt6428 4 года назад

So let me get this straight Gerald. I'm always shooting all my paid work in 50fps / 100 shutter and converting the clip to 25fps before editing. Are you suggesting that my shutter should also be 50 instead of 100 since I'm a slow motion freak to get that natural motion blur (50fps / 50 shutter) ?

@dlarva77 4 года назад

If you are shutting for slow motion only, follow the rule 1/100 is the best way, but if you will only slow down some parts is better to use 1/50, Is better to have an slightly blurrier slow motion than a choppy playback at real time.

@kizzume 4 года назад

I must admit: I'm confused as to why you made this video in 24fps. So many of the points you're trying to make would have been more succinct in 60fps, even if much of the footage would have still been in 24fps. It was an interesting video nevertheless. Thanks for that.

@AlexUtreras 4 года назад

I always fight with my colleagues because of the extreme importance they place on shutter. For me, achieving accurate exposure is the most important thing, and when you don't have ND and you want to prioritize a certain aperture, sacrificing that "naturalness" of the movement a bit is the least important thing. Of course this example of the spinning rule is great, but my fights are when you're doing an interview with a guy sitting still and they start to bother you with the shutter and it's like ... Nobody will notice. Great video anyway, as always.

@harveylouis445 7 месяцев назад

My thoughts exactly. For aperture, I try to find the best balance between enough depth of field and not too much diffraction. For ISO, I like shooting at one of the base ISOs for best results. That leaves the shutter speed to adjust for the amount of light. Personally, I barely notice any difference when people are fairly still.

@RLubachesky 4 года назад

His test method seemed quite efficient and his observation about the expectation of the amount of motion blur seems to me to be the key. Fast movements cause the expectation of more blur, so the rule works well. Shooting at 120fps something that doesn't move fast doesn't make sense and for fast movements, respecting 180 is the most efficient way to balance the blur rate. However, the frame rate of the human eye is variable, it falls considerably in low light and we see more blur in low light. I think that footage that feels like night should have more blur compared to footage that gives the feeling of a well-lit environment. This seems to me to be a special point to be explored in the creative construction of the footage.

@geraldundone 4 года назад

That's a very interesting idea. Cheers!

@andreasbuder4417 4 года назад

I absolutely don’t follow the 180 rule higher than 30fps. Literally nobody outside of tech nerds notices, and it would be a major hassle to use ND filters and therefore kills documentary shooting and run‘n‘gun. I don’t bother anymore, I did for way too long, because everyone screamed 180 degree without any factual argumentation.

@andreasbuder4417 4 года назад

To further emphasize: I use shutter degree angles of 45 or even lower, when shooting at 60fps, really nobody cares like at all.

@ramabg2 4 года назад

Finally. The most bothering thing in my mind about shutter angle has been answered. Thank you for answering this question in such scientific and objective manner. This is very obvious question that has never been answered properly since the invention of high frame rate video.

@mylhainen 4 года назад

I think frame rate preference comes down to what you are used to. Movie/film nerds tend to prefer 24p. However: ru-vid.com/video/%D0%B2%D0%B8%D0%B4%D0%B5%D0%BE-uUF9Wxc7xoY.html

well then... I usually shoot at 1/60th when using 60p, because I don't want to lose light...
