60fps..and for the sound?

[Mounir]

I'd like to try to make 60fps with yadif for instance but what about the sound part?
What should i use to keep the synchro ?

Inputs welcome :thanks:

It's the same duration whether you use mode=0 (single rate deinterlacing) or mode=1 (double rate) , because you have 2x the number of frames using mode=1, but 2x the framerate also. So the sound will still be in sync either way (assuming it was in sync to begin with)

Thanks i will try today

If your framerate changes and your audio isn't in sync just input your changed framerate into assumefps with the sync_audio option turned on and add it to the end of your script.

If your changed frame rate is 59.94fps, then add,

assumefps(59.94,sync_audio=true)

To the end of your script. Normally, bobbing shouldn't cause audio sync issues, since you're only doubling the frames.

If the audio is out of sync before AssumeFPS(sync_audio=true), it will still be out of sync after it. Sync_audio doesn't sync the audio as such, it keeps the ratio of audio/video durations constant (by changing the audio sampling rate).

I'm assuming the audio is in sync before the framerate change.
