UPDATE:
I forgot to explicitly mention an important workflow detail:
Basically, WHEN YOU GET PRETTY MUCH ANY FOOTAGE, after you import it into Premiere (or whatever NLE you use), before you put it onto the timeline, YOU SHOULD CHECK THE FRAMERATE. Do not assume that it will match your timebase. It's always possible that the camera operator made a mistake! (The framerate can be checked easily and quickly for lots of footage at once, using the List View in the bin (the bin is also known as the project panel.))
If any of that footage has a framerate that is DIFFERENT from your timebase, then you can use the techniques I've described here to try to alleviate that.
However, keep in mind that SOMETIMES, the listed framerate isn't correct, (visibly) because the clip was ruined by another editor, as described at 14:04. As your editing skills improve, you'll be able to spot a framerate mismatch like this while playing the video at 100% speed. (You will never notice a framerate mismatch at 200% or 300% speed.) However, the best test for this is ALWAYS to just watch the footage frame by frame. While paused, just slowly hit the right arrow key, (to advance by just 1 frame) over and over, and carefully watch the monitor. Repeated frames will immediately become obvious. This will usually show up as one repeated frame per 5 frames, which is what I meant when I say "according to the appropriate spacing" at 13:05. But this absolutely can sometimes be at an interval other than once every 5 frames! The frame-by-frame test will always show you where those repeated frames are! When you spot one, keep going frame-by-frame. Don't always assume that the interval is constant, like I did with that footage from Apple! (Which I then notice and fix at 13:24.)
As mentioned, SKIPPED frames are harder to spot, but can most easily be seen during panning moves.
NOTE that the results of this test may be different depending on if you are using the Program monitor or the Source monitor! The Program monitor is using your Timebase, while the Source monitor is not. The Source monitor always shows your video clips exactly as they are, before they are altered in any way by the Sequence you place them into.

If video editors were written from the ground up to internally work at that frame rate, there would be so many fewer issues with mixing different materials in the same project. No matter what you imported, every single frame would be perfectly positioned, and only the render would need to worry about picking out the right frame to export.

I'm so glad you covered fractional frame rates here, I was planning on making a video on the topic myself because I'm so fed up with all the misconceptions around them. I've seen far too many reddit and other forum threads where beginners ask whether they should use 30 or 29.97fps and get snobby responses from industry veterans stating that you should always use the fractional ones and that true 30 doesn't even exist. Regarding Twixtor, I think it's great because of how many different options and parameters you can tweak. Modern AI frame rate interpolation software creates a better result than Twixtor with default settings, but as an editor you can poke around quite a bit in Twixtor to get the perfect look for each clip individually. And something to add about gameplay footage - sometimes it makes sense to record games with a very high frame rate to later add motion blur through frame blending. Camera footage doesn't need this because there is already naturally occuring motion blur, but games usually either don't have any motion blur or just have some crappy filter thrown on top that doesn't look smooth in post.

In the old NTSC days, 24 fps film was converted in real time to 30 fps by using what was known as 3:2 pull down. NTSC video actually ran at 60 fields per second because video was interlaced video: Field 1 was the odd lines and Field 2 was the even lines. 3:2 pull down showed 1 frame of film for 3 fields and the next film frame for 2 fields. This pattern was repeated for every 2 frames of film with the result being film running effectively at 30 frames per second.

My guess on the Red Pan Calculator is that resolution does matter. As in, the resolution that you set you Red camera to. Many professional and cinema cameras will perform a sensor crop when you drop down in resolution instead of pixel binning. This will increase your footage's focal length as it's only capturing from tighter and tighter crops from the center of the sensor. Thus, for a subject at a fixed distance, when you drop down in resolution you should slow down your pan, so that it's not moving too fast across the screen.

This is a great video. A couple of the problems you mentioned could be solved using third party programs like ffmpeg. For example, I would never input 29.97/30 ABCDD footage into a 23.976/24 Premiere project, I would just drop the frames before and transcode it to a lossless codec. Your method of manually blocking all of the dupe frames out and then cutting and combining them is super time consuming and cumbersome when you could easily do it with ffmpeg, or even probably some third party front end like Handbrake if you wanted a more user-friendly GUI. Same goes for interlaced footage if you're importing HDTV/DVD, just deinterlace/IVTC it before it ever even touches Premiere since Premiere sucks at it. This applies again to variable framerate footage, there's no reason to ever import VFR into Premiere as it can't really handle it without losing audio sync. As a side note, I was excited to see at the beginning you were maybe going to explain why Premiere ANNOYINGLY changes 23.976 to 23.98 even though they're clearly different things. This can occasionally lead to weird problems with already edited/cut 23.976 footage where the beginning or ending in/out frames are off by 1 on a "23.98" timeline. Super frustrating. Thanks for everything, nice to see you thriving, looking forward to future videos!

1. the detect-edit portion to apply optical flow might be easier by nesting the individual shots. optical flow is then unable to use visual material of the next shot, which we don't want. this should result in a consistent length as well that syncs with the slowed audio if ever needed. you could also preemptively remove 1 frame at the end of every shot before slowing the shots down, should also work but makes the entire thing shorter like you said. 2. i used twixtor back in the day when optical flow wasn't a thing (in after effects too) and it was really cool for it's time but with optical flow as a native feature i don't think it's worth it. it has pretty much the same issues.

This is the type of video I didn't know I needed to watch, but I am glad I did. I am fairly green in editing environment and had some work done that looked wrong, mostly due to mismatched frame rates before and I even had no idea what could be an issue there, or how to work around solving these issues, since I couldn't find the roots of the problem before. The delayed sound issue I encountered on multiple occasions too. This was very enlightening video to me and I believe to many others as well.

mp4 containers actually can use a variable framerate. It's just that most editing software can't do that and a lot of software isn't expecting it. You can even put a 60 fps video in a container that says its 30 fps. Premire will retime the clip to 30 fps while vlc will play it at 60 fps while telling you it's 30 fps. Just in case you want to want to manipulate video metadata at some point ;)

I think the vast majority of screens aren’t VRR just yet. Smart TVs started being VRR since 2020 with HDMI 2.1 consoles, and that’s still not all TVs in 2022. Flagship phones and laptops are beginning to get higher refresh rates and VRR too, but it’s still pretty recent outside of PC gaming.

@marcofazio1318 Жыл бұрын

A good practice for variable framerate footage would be to transcode it to an intermediet codec (prores/DNxHQ) or any other codec of your choice that uses fixed framerates. That would lock audio and video as they are avoiding the sync/ issues you experience editing it natively (without transcode first). And that's much easier/faster than shift andio every paragraph manually.

I only ever shot at 60 all the time was to always be able to slow down a clip in my videos although nowadays I don't do that as much so back to 30 it is.

About monitor framerates: when watching ANYTHING on a computer with a single monitor, EVERYTHING gets displayed at the framerate the video graphics chip is set to. This includes what you're watching in Premiere or any other NLE. TVs may be able to adapt to the signal coming from a Blu-Ray player, game console, or camera, but when the computer says the monitor shall run at 60 FPS, this applies to all applications running on that desktop. This MAY be overridden when watching video on a second monitor in full screen mode, but if you're using a single screen, your NLE is resampling (and stuttering) your 23.976, 24, 25, 29.97, 30, 50, 59.94, or 60 FPS timeline to whatever your monitor is set to.

@@NUCLEARARMAMENT Sometimes twixtor can work well. As often as not twixtor is worse than mixing framerates without interpolation or mixing to a common framerate. Twixtor can be something to experiment with, but I've not found it useful explicitly for combining framerates in the same project. 119.88 is a fine project framerate when working with multiple source ntsc framerates; the high common framerate means that all source material displays as recorded and irregular frame time issues can be avoided until changing to some lower framerate.

Don't even know what to write here after this 1h30 doc on framerates. I don't even imagine the work u've put into this man, but it made my life so easier. My intelligence level just grew some points i think kkkk Thanks4sharing, I'll download your sponsor's game in sake of this video. I'll be sure to watch all ur content. again, thanks a lot!

Live video technician here. Interlaced is still very much used in a LOT of "TV style" streaming setups and I refrain myself of setting 100'000's of € worth of equipment every time it crosses my path. Also from a European point of view: I'm glad I don't have to deal with NTSC fractionnal framerates. Also, KZfaq re-samples every 25 or 50p stream sent to them into a 30 or 60p stream.

Given that I can frame step 25 and 50 fps videos, I don't believe KZfaq does, no. It will be nearest-resampled during the composition(?) of your desktop by your OS, if your browser never engages exclusive fullscreen, or if your display doesn't support VRR.

KZfaq honors the upload the framerate (unless it is more than 60fps, in which case it converts back down).

@1:03:14 My thought about RED's calculator is that RED's different resolutions are all cropping in on the sensor, so they're kind of NOT the same focal length. This is one of my biggest, aside from them using cheap Chinese parts, reasons I haven't bought a RED.

The answer to all the (very valid and awful) frustration in the last ten mins is just... use PAL. This (plus metric) makes me so glad I live and work in the UK. Amazing vid btw.

thank. this helps a lot. mainly the fractional frame rate. Also explains why I couldn't mix some gopro footage at 29.97fps and camera at 50fps, had a feeling it was to do with that after a lot of frustration but now makes a lot more sense

Absolut treasure trove of framerate information here! Thank you

The key takeaway from Matt Smith’s video is that 59.94 and 29.97 etc. aren’t exact anyway because they’re actually (1000/1001)*60 and (1000/1001)*30 etc., respectively. So to fix timing issues mathematically in AE, adding “(1000/1001)” or “(1001/1000)” to your AE scripts should fix the smearing & other related issues.

Interpolating the audio and just running the clip a little faster/slower is probably the best way to deal with small differences in frame rate. It's what they did to put movies out in PAL regions before TVs could run at anything but the local analog TV frame rates.

Despite the comments memeing about the duration and level of depth of this video, thank you for providing valuable in-depth lessons on these things. Your presentation is easy to understand and I learnt a lot, as I'm looking at getting into video production and am facing a choice of what format to use. Keep up the brilliant work.

The best part of fractional frame rates is that 23.976, 24.97, and 49.94 should not exist. 29.97 exists so *NTSC* was compatible with both BW and color. PAL just dropped support for BW altogether, and the other necessities for PAL color were made with the hindsight of NTSC's 29.97 mess in mind.

Excellent video. Framerate mismatch is always a pet peeve of mine, I seem to notice it even when friends and family don't. A personal trick, for complex or messy sources like 'old footage' which may be improperly telecined and/or (de)interlaced, fixing the source with ffmpeg before it even hits the timeline can allow massive improvements (at the cost of extra steps, storage, and transcoding)
