Topic: Can RIFE be forced to output 59.940 fps?

I’m encountering an issue where RIFE always outputs a framerate of 59.524 fps, which causes problems in editing software like DaVinci Resolve. Resolve automatically converts this to 59.940 fps, resulting in audio desync because the video duration changes.

My question is: Is there any way to force RIFE to output 59.940 fps directly? I don’t understand why it defaults to 59.524 fps, since multiplying the source framerate (23.976 fps × 2.5) should result in 59.940 fps.

Thanks in advance for your help!

Try the Automatic profile to save your video at a 2.5 ratio.
Will you also get the wrong framerate of 59.524 fps?

Always, in automatic mode, on Rife models. I don't know what else to try to fix it.

Thanks for your reply.

"always" with any source video or "always" with this particular one?

Always, with all the videos I've tested so far having a frame rate of 23.976, even if I use the fixed 60fps option, I don't know if you can check it yourself.

Thanks.

dunno, got 59.94 as intended...
please show the transcoding log

Re: Can RIFE be forced to output 59.940 fps?

dunno, can't reproduce

but this's not about "RIFE", but more like encoder behavior
try software x265 mode

H.264 NVENC, H.265 NVENC, Same results when encoding.

Testing AV1 NVENC.

They're the only ones that support bt2020 for HDR.

The truth is that it is very strange.

Re: Can RIFE be forced to output 59.940 fps?

I mean try something other than NVENC.

Re: Can RIFE be forced to output 59.940 fps?

For now the tests with VC1 are all good and without problems, the only thing is that it creates it at 59,940, but when editing it must work at 60fps, the NVENC codecs all give 59,524, it is clear that the problem is with the codecs, I don't know if it could be forced but with VC1 you can work without desynchronizations, I will continue doing tests if I discover something else, I will let you know, in case it helps anyone else. aid.

Thanks for everything.
