Best practice for converting 24p to 30p
Hello,
I realize there are a lot of questions of this nature… what I’m trying to figure out is what the differences might be in the approaches I’m trying and some advice on best practice if anyone has found a sweet spot. I have been given 1080p 24fps footage from multi-camera shoot where the rest of the cameras are 29.97 1080p. I have to convert the problem footage from 23.98 to 29.97 so that the multiple cameras/sound will line up correctly. Just pulling the 24 footage into the 30 timeline in Premiere doesn’t seem to be the way to go. So here’s what I’ve tried:
– I’ve tried simply using AE’s frame blending in the comp, importing 23.98 clips and dropping to a comp, changing comp frame rate to 29.97. and rendering. This keeps the duration.
– I’ve tried using Andrew Kramer’s frame rate conversion preset (which seems to just time warp and interpolate the footage.)
– I’ve tried various MP render settings (and mostly have remained frustrated at inconsistent results, various errors sometimes, sometimes not. IMO AE makes this WAY too much of a tweakfest.)
The Andrew Kramer preset method is a lot slower. I need to do this for about an hour of footage in about 20 clips unfortunately, so I’m trying to figure out what the best practice here might be so I can standardize my approach.
All I’m trying to do is conform the 24 footage to a 30 timeline, not convert for broadcast. Anyone found a tried and true method for this?
Thanks,
Learning. Always.

Thanks, yes, sorry, the footage is 23.976 and the target timelines are 29.97. I referenced “30” and “24” incorrectly.
The reason I ask is because it’s a multicam setup and the other cameras are at 29.97. This one got screwed up and is at 23.97. So I want to get them matched up. All progressive DSLR footage.
I don’t “need” to match the motion perfectly but had just assumed that if I were dropping 23.97 clips into 29.97 sequences in Premiere that things would look a bit choppy, if it was just adding frames to compensate.
Truthfully the issue of pulldown is confusing to me as I thought it was only for interlaced footage. Thanks much for the reply.

You could try turning on frame blending when converting. It won’t be as good as Twixtor but it might work.

Thanks, I did take your advice, tried a couple of options, retiming, frame blending, and then… just dropping the 23.97 footage in a 29.97 sequence in PPro. Oddly enough, just dropping it in and not converting anything rendered results that seem just as good if not better than what I was getting from hours of rendering in AE.
This doesn’t make a lot of sense to me, am I missing something that will jump up and bite me later here? I honestly can’t see any stutter in the footage, which is confusing me a bit I have to admit.
