What is a good way to convert from 29.97fps to 23.976fps?

[jsj2251]

I want to combine the texture of the vintage camcorder with the feeling of 24 frames.

After changing the sequence setting to 23.976 fps within Adobe PP, a weak break occurs when playing.

Is there a better way?

Looking at the other posts,

It says to use Reel Smart Motion Blur or Motion Flow, but I don't know what it means exactly.

Wouldn't it be better to use 3:2 pulldown to bring 23,976 to 29,970 instead?

Anyway, if you wanna stick with going from 29,970 to 23,976 and you think that decimating it makes it looks choppy, you can use (people are gonna hate me for suggesting it) blending.

Isn't 3:2 pulldown a technology that converts from 24p film to 60p digital video?

Sadly, my vintage camcorders do not have 24P function...

It essentially means that you have 3 real frames and two repeated ones, 3 real frames, 2 repeated ones etc.
So essentially, you're going from 23,976p to 29,970p.
In the interlaced version you're referring to, instead of frames you have fields but it's exactly the same: 3 real fields, 2 repeated fields, 3 real fields, 2 repeated fields etc and you get a 29,970i stream that the TV then bobs to 60p, but the real original footage is still 23,970p.

I see. Anyway I would actually suggest you the software we've been working on (me, steipal, momocampo, emcodem) called FFAStrans. It's based on Avisynth and it will handle the frame rate conversion for you, including the encoding part, before you import the files into your non linear editor.

If you use Avisynth, I found FrameRateConverter does a pretty good job of converting 29.97fps to 23.976fps. Admittedly I've only used it for that sort of conversion to change the opening titles of a TV show to 23.976fps to match the frame rate of the actual episode, but the result was pretty good. It can't hurt to try it. I haven't used FrameRateConverter v2.0 beta, only version 1.3.

V2.0 beta better than 1.3

*gig* Didn't know one could use FrameRateConverter to reduce frame rate/count, I only used it to increase the frame rate&count.

Using ffmpeg, this gives a smooth playback

-vf "minterpolate=fps=24000/1001:mi_mode=blend:scd=none"

Uses blend mode, so produces 'ghosting' on the object edges. Simplest and about worst metod.

If file is real 29.97 (without pulldown) then there is no easy way. You need to interpolate frames using motion adaptive technique.
Mentioned FrameRateConverter is about best you can do.
