This Enable pitch compensation checkbox is used to restore the pitch of the audio on a video clip.
In my example here, after speeding up the video to 1.5, the actors sound like chipmunks.
After checking the Enable pitch compensation box, the video and audio are still running at 1.5 times the original speed, but the voices are back to their normal pitch.
So in this case, we will need to split the clip so we can work with keyframes… I guess.
There’s also this visual modality thing. I wonder what this means?
