I ripped a YouTube video from the web and loaded it into SMS Platinum 13.0. It's an .mp4 file. I want to slow down the picture and sound together in sync so I can study the picking style of Tony Rice - one of the best flatpicking guitarists in bluegrass. Once I have the file in my timeline, I can right-click on the video track>properties>playback rate and choose to slow down the speed (of the picture, anyway). When I played it back, however, the picture was slowed down but the sound track was normal speed - obviously they were out of sync. I noticed that if I right-clicked on the sound track>properties the choices there are different - and there is no choice to slow down the music track.
Can picture and sound be slowed down for playback in sync?
