Difference in Frame rates 24fps vs 30fps vs 60fps | AVI

You used the same video and cut them into 3 parts. That wasn’t the best way to illustrate frame per second.

I think this may be a little misleading for those not overly familiar with filming, editing, shutter speeds and global differences. Shooting at high FPS is fine but if you downgrade from say 60 to 24 you are reliant upon software interpolating the dropped frames which can cause stuttering. Shooting in frame rates in multiples of each other can help avoid that if you then understand that in post. I shoot 24, 48, 96 for example. You describe a frame rate multiple of 24, 30 and 60 only but outside of the US PAL of the standard format for most viewing so 25, 50 fps. Also it helps to understand the effects of shutter speed on output, overcranking, undercranking, deflicker in different countries under some lighting conditions. After watching this many people will go out stick their cameras on 60fps and then hit problems if they try and edit in clips from other cameras for example. I appreciate this is an FPS guide only and I'm not trying to be the smart arse here just think some of your viewers will be scratching their heads if they film at 60, drop to 24 for render and then can't fathom why they have stutter

24 FPS is not the slowest that the human eye can see as continuous - that is about 15-17 fps (early silent films were about that frame rate). 24 FPS came in when sync sound became a thing - 24 fps is the slowest framerate that could match the playback of the audio system at the time.

I didnt come for talk, I came for lenghty comparioson side-by-side, AS SHOWS IN THE THUMBNAIL

It is weird to me, because all 24fps movies seem to me smooth, but when I watch any other videos at 24fps it looks choppy...

While I liked that you included example shots, I didn't like the shots themselves. They would have been much better if there was movement across all three sections. Most of the time you didn't really have a direct comparison. the first shot was decent though, there were a couple of cars driving through all three sections.

I wouldn't recommend shooting at higher FPS just because you can! Of course, you can export it at lower framerates in post; But shooting at higher framerates comes at the cost of a higher shutterspeed, meaning not only that your images are going to turn out darker (you need more light / wider aperture), but also without any Motion-Blur which is the key to make something look 'cinematic' or generally 'smooth'. It completely changes the feel of motion and is actually the reason many people dislike movies at higher framerates - because it looks unnatural.

[WyvernApalis]

Just because I can film in 120 fps doesn't mean I should.
This is a wrong tip especially for people who want professional cinematography or is shooting in low light.

[D.man]

How can we see 60 fps if we only have 24 hours a day??? 🤔

[McIntec]

Actually, The Hobbit was shot at 48fps. Double that of 24fps used for the motion-blur film effect. Still a great video! 👍

[BenoitAdam]

3:09 this is a mistake

24fps from a 60 fps shot will look weird, because 1/6 of a frame is being remove.

So you will have a little "pop" every 6 frame.

[hannahbee]

Oh my gosh, thank you. I've be curious as to why YT/TV/Cinema looks so different now and again, and this has just visually presented it. Wish the comparison video was longer and of more variety, but cheers!

[BrodeOne]

NEVER shoot the highest frame rate and edit that in post. please ty

[henrickcamacho]

IM SORRY BUT ITS A BAD IDEA USING 60FPS ON YOUR CAMERA AND CONVERTING IT24FPS WHILE EDITING THERES A VIDEO ON THAT THAT SHOWS THE EFFECTS BECOME CHOPPY SORRY FOR TYPING ALL CAPS MY KEYBOARD IS BROKEN

[BobDiaz]

The silent movies were around 16 FPS and showed motion reasonably well. The switch to 24FPS for sound was to get better audio. When shooting 24P, the exposure time needs to be close to 1/48 of a second, anything shorter causes a strobe like effect in the video. The rate of 30P isn't as sensitive to that shutter speed and 60P really doesn't matter.

[HariKristiyanto]

Any recommendations for the best fps for 4K video for video on a tripod?

[hornet]

THANK YOU FOR THIS!!! As starting out in film, I have been search through training videos for simple answers and I get a lot of people yelling or being over-dramatic with their answers. You explained it to me in a clear and concise way. THANK YOU!!!

[Ben_Cheng]

Information in this video is misleading. One should film at the exact framerate one is planning to export the final product in. Reason being, to get a comfortable motion blur, the shutter speed needs to be 1/2x, where x is the framerate. ie, for 24 fps, shutter speed should be 1/48 to get comfortable Hollywood like motion blur per frame. For 60 fps, that would be 1/120 shutter speed, essentially lowering motion blur per frame as there are now more frames per second to fill in the gaps.

If one applied this rule of thumb for 60 fps and decides to bump it down to say, 30 fps by losing half the frames, the video will seem very choppy. Of course, artificial interpolation between frames can be done to fake a higher motion blur, but results will be quite inferior / unnatural compared to the shoot it as how it should be published method!

[Adamj]

Sorry if I’m being a knob, but if I wanted to video something moving quickly, I’m better with 60fps right?

[DimitrisDram]

I cant be the only one triggered by him saying frames in a second instead of frames per second? Especially at the beginning when he defined it.
