The clip chain
How AI Vids chains clips so each starts on the last frame of the one before, stitches them into one file and keeps cuts and end pictures.
Each clip starts on the last frame of the clip before it, so the video has no visible seam, and the clips are stitched into one file. A cut starts a clip fresh instead. You can end a clip on a picture where the model allows it. Preview and Long take differ: Preview takes end pictures; Long take does not.
