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?

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.

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.

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....

@@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.

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. (We are in Europe and we use PAL format, this method won't work with NTSC 60p/24p combination)

Why not just shoot at 1/100 the whole time?

Such a helpful video. I’ve always used the 180-degree rule but never thought to experiment with lower shutter speeds with higher frame rates played back at those higher frame rates. This should be a must-watch for anyone uploading a video to KZread.

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.

THANK YOU !, I've tried to explain this to soooo...many people in the past I've given up, no one understands but it's all based on math and time which never changes no matter what the frame rate.. amazing video man !!!!

Thanks for putting that together! A fantastic basic test! Time to do a little experimentation 👍

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.

Thanks Gerald, you're the only guy on KZread to explain this properly. I couldn't find anyone else to answer what makes the major difference to motion blur - is it frame rate or shutter speed? - and you answered it as the first question.

THE KING OF KZreadRS - not even close- THANK YOU GERALD!!!!

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.

@thatcherfreeman

3 жыл бұрын

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

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. 😜

I've always enjoyed iphonedo but now it's love.

This video is so personally satisfying. Many years ago I got tired of listening to all these rules when filming. So, I did my own tests and fell in love with with 48fps at 60 shutter. No client has ever noticed/complained. Looks good to me, and that's all that matters.

Wow, this was very helpful, thanks!

so many other videos talk about the shutter speed like it's the most important decision you will ever make in your life... This video really helped put it into a more reasonable perspective for the average video creator. I'm glad to know that 60 @ 1/60 works well for real time, because at 1/120 my camera gets too dark. I should have just trusted my eyes and realized at 1/60 it looks good, but all these people treating the 180 degree rule like it's a commandment got in my head and misguided me lol.

I have been using the 180 rule on all my vids, but am now going to make adjustments for higher frame rates and slowed down vids. Thanks for those two suggestions. Sure wish I had half of your knowledge...I might actually know what I am doing. Great stuff Gerald!!

Awesome job as always! Crazy stuff.....crazy stuff

This is a fantastic video!! So helpful!! Thank you!!!

Gerald you are possibly the only vlogger that makes videos that consider slowing down. Amazing content as usual. Oh and 11:25 LOLOL!

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.

Very good video... Helped me sort some things out. thank you.

For ages i've being ignoring the 180º rule on purpose and made it a characteristic of my work (usually i record 30fps at 1/50 but even on 60fps i keep 1/50) and people always come to me saying "hey dude, your shutter is wrong, it must double the fps" and i'm all "yeah yeah, i know F*** it, i like more this way because blur), even teachers on my photography direction class, and they think i'm crazy and i'm sh*tting on the sacred rules of fotography and that Lumiere brothers are cursing me in the afterlife because of this. Thank you Gerald for making this test, it shows me that im not that crazy (or that we are) and i have some basis on my line of work.

Thans for this and very helpful for a n00b. The 180 degree rule for 24p/30p timeline was understood and has been working well, but i was unsure on the 60/120 shots for use in slow motion situations and this has made things clearer!

Loved this one so much! 😂

When shooting drummers, I find that using 1/80 shutter speed at 24fps gives you the best look. It's slightly choppy but the motion blur is still present.

Great info, thanks!

Quantative and qualitative analysis. You are the best!

Great video. There is so much nonsense talked about this topic, with many pundits failing to account for the project settings, and blaming judder on the frame rate, when all the time it is a mismatch between shooting frame rate and project frame rate. You deal wi9th this correctly, and supply very convincing evidence.

FINALLY GERALD UNDONE making a Tutorial... 10 seconds in...oh dear.. here we go again

Man I love your videos!

Thank you! This subject is ineresting for every videographer ;)

And just like that... you gave me a new way to think about shooting in 60p knowing some of it will be played back on a 24fps timeline, at normal/real-time speed (dropping frames). I always follow the 180 rule, and then hate the real-time segments for being too choppy. I’m going to experiment to see if I’m OK with the extra motion blur on the slo-mo in exchange for smoother-looking real-time. (The joys of having just one camera... and only one take... choosing a shooting frame rate, and having to live with it for both slo-mo and real-time during playback)

I wonder if setting up the drill so it was pointing towards the ceiling and shooting above/below would had been smoother, no ramping speed for the nitpickers. Though, I don't think the way it was done was a problem, and having slight different speeds helped get different blur conditions.

I nearly spat out a mouth full of weetbix laughing when I saw iPhonedo’s desktop image.

Excellent video! It's an interesting interpretation of the 180 rule, and it makes a lot of sense. Cheers!

This is THE explanation of the issue. Thanks!

Lately in post production, I constantly come across the use of slow motion (at 60fps or 120fps ) that is time remapped to go fast then slow then fast (think Guy Ritchie style). I often times have to add fake motion blur to reduce the choppyness on the sped up remaps. Great video G.

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

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.

this is the video i needed 😭😭😭 thx

Excellent video Gerald (as always) great to see a great example and opinions of others into the mix. Definitely something about the 360degree that I like though, not sure what it is!
