Slowing Down Audio

PostSun Aug 14, 2022 10:18 pm

I have a clip playing at 25 fps. I want to slow it down to 24 fps. The change in pitch is acceptable.

If I set Mixed Frame Rate Format to Resolve, I can change Clip Attributes for the video, but this won't slow down the audio.

If I set Mixed Frame Rate to None, I can't change the Frame Rate in Clip Attributes.

Is there a way to change the fps for both video and audio together?

Unlink the audio from the video and use Elastic Wave in Fairlight to stretch or shrink the audio.

I could.

No one knows of a way to do it in one go?

- set Mixed frame rate format to None
- set the timeline to the frames per second you want
- put a clip on the timeline

The video will play according to the fps timeline.
The sound will be adjusted to the length of the video. (But it won't be as good as when you use third-party software - Time Factory 2, iZotope, Serato, etc.)

Ahh, that's why the Clip Attributes is locked. It simply adjusts automatically to whatever timeline it's in.

Nice!
