Preparing a Video to Rotoscope with Premiere Pro
Why? Animating every single frame of a video can often feel tedious and unnecessary. Most animators rotoscope on 2s or 3s. To animate on 2s mean to animate every other frame of a video, meaning that if you have a video shot at 30fps, you're animating at 15fps. To animate on 3s is to animate on every third frame, so your animation frame rate would be 10fps. Editing a video so that it matches the frame rate you want to animate on is step one to efficiently rotoscoping!
Preparing the Video
- Select a video to animate over
- Trim the video in Premiere so the start point is the first frame of your animation and the end would be the last.
