So I believed I posted this topic months ago about how to slow down the music. Basically, I wanna achieved the effects like they have in the Musical.ly app (or whatever the app is called) where the person is moving fast while the music is playing at normal speed. I normally do dance videos where I sit my iPhone up and record myself on my iPhone while the music is playing on my laptop through Sony Vegas (at normal speed) then when I’m done I plug my iPhone in and convert my file to an mp4 then drag it onto S.V. I know I can stretch out the audio and my video at the same time but the audio is always changing. It sounds like a chipmunk. Any suggestions???
