How to use it
Full replacement
The previous audio is not mixed in: the result has only the track you uploaded now.
Sync
The new track's start is set in seconds, so it can be aligned to a line or a specific cut.
Duration
If the new track is shorter, the video ends in silence from the point where it stops.
Examples in practice
New voice-over
