converting frame rate in after effects 29.97 to 23.98

here’s compressor’s method

if you ever get AE as a trial, try these templates.

if you have any flickering, white balance issues, try my free ae auto whitebalance

extra:
always fix the white point, black, gamma, then white balance first before doing color correction. you can use curves(transfer mode color) to separate the colors at the shoulder. always sharpen after color correction. also, you might need to stabilize the footage if you have gate weave. remove grain if applicable.

Thats brilliant, thanks so much! Compressor worked.

I set the duration to 150% of source and this looks about right – hard to get my head around this as I’m used to reducing the percentage in fcp in order to slow it down, not increasing it. Any idea what the correct percentage is for making stuff shot at 18fps but scanned at 24fps play at natural speed? Tried to search online for an answer but I can’t find it.

its 18/24(75%) so…
it might be 125% which is 100-75=25% slower(backwards of timewarp) like timestretch

Strangely, the way that I am doing it (possibly wrongly) both of those settings seem to still result in footage that is too fast. 150% seems to be about right, and it looks good so I think I will stick with that. Thanks for all your help.

Interesting — does the TimeWarp filter with Pixel Motion not internally deal with interlacing?

I just handled this process in a way that seemed fairly intuitive with some 29.97 stock footage that I needed to use in a 23.976 comp.

• dropped the 29.97 footage into my 23.976 timeline.
• set AfterEffects’s interpretation settings for the 29.97 footage to conform it at 23.976 (result: no skipped frames in the timeline, but it’s running at 80% speed).
• In the timeline I applied the TimeWarp effect to the footage and set it to play back at 125% speed with ‘Vector Detail’ 20 and Filtering ‘Extreme’.

This looks pretty much perfect as far as I can tell. But I may have gotten lucky in that the stock footage appears to be progressive.
