Differing Frame Rates

[ron spencer]

So I have some 1080p 60fps video from our camcorder. It's all OK. But I also have some from my Nexus 6p phone, which is 1080p 30fps. I'd like to use it with the 60fps video. Is there something I can do to combine them? I've never used multiple frame rates before in Vegas, or any other NLE
Thx

Yes you can use mixed frame rates

If your project settings were 60.0 (not 59.94), and you had 30.0 assets from your Nexus, every second frame would be duplicated on the timeline for that footage. It's nice because those are evenly divisible numbers, so don't get any judder cadence . It's the same idea if you had 59.94 and 29.97 . Make sure you disable resample if you want true duplicates. Otherwise you will get blended frames (ghosting) if you had smart resample enabled which is the default

Hmmm....The camcorder, a Canon Vixia HF G30, shoots at 59.94 fps, while the Nexus 6p is 30fps. Will this still work with it not exactly evenly divisible?

yes of course it will still work, but it won't be as "perfect." There will be a very slight periodic studder (but 99.99% of people won't be able to notice it) . Instead of a duplicate pair, you'll get a single frame about every 3000 frames. Just try it out yourself

Whenever you use mixed framerates in a NLE, every asset conforms to the project settings or timeline setting FPS. So if that was 59.94, the NLE "makes up" the frames by either dropping frames (if FPS is > project FPS) or duplicating frames (if FPS < project FPS) (if resample is disabled) , or by blending frames (if resample is enabled) .

And there are ways you can make it "perfect" . You can interpret the phone footage as 29.97. Essentially you're slowing down the footage a tiny fraction. Every frame in the original is still there, just played back more slowly. The audio has to be slowed as well. And if you're not using the audio from the phone footage, that's even easier.

And if the phone footage is "VFR" (variable frame rate, you can check with mediainfo view=>text) , you actually have other problems. It cannot be edited reliably as is. You would need to convert to CFR (constant frame rate) before editing
