How much are you stretching?
Is it music or voice?
You can do a time stretch, but it will distort the audio some.
Voice Audio. Only stretching a few seconds of video for slow motion effect. I figured out that when I do a "time stretch" the audio changes accordingly, but when I use the "Time remapping" tool the audio does not change. What's the difference in these tools and why is the audio feature different??
Time stretch stretches a clip uniformly.
Time remapping allows changing the speed uniformly, gradually, or quickly. You can also have several instances of different types of time remapping on the same clip. You can speed it up, slow it down, pause it, reverse it, speed it up, etc. all done on the same clip.
