It does it automatically. Just check the frame rate of the original video and set that in Studio One after you import the video. It's at menu bar > song > song setup or [CTRL+.] After that I just figure out tempo, where I want changes, and heavily use markers. You have to extract the audio from the video, it's on the menu below the video, otherwise when you export you won't have the audio from the vid (I usually don't bother until right before I'm exporting). And you can set the offest from the same menu. That's really it. It's pretty straight forward, no weird tricks needed. It's just not as nice as a having a video track but it works, I just have the video really small playing in the corner to help keep track of things.How do you sync the video to S1?
