What happens inside one AI-made episode: units, redos, versions and the cut

Timeline term: start and end frame

A start and end frame are images given to a video generation as its first and last pictures. The model fills in the motion between them. From 5 source pages, read 2026-09-25; no maker pays to be listed.

Fig. 1 Definition written for the register; editor wording quoted in the table.

Three editors use frames to control joins: the end frame of one shot becomes the start frame of the next, so motion carries across the cut.

Frame-based joins suit continuous action; a cut between places needs no shared frame.

You can create transitions, animate images, or generate a video that starts and ends with specific images with the use of frames.

2From an episode pipeline

The episode pipeline SceneMixer documents has its own answer to “Start and end frame”; two lines from its pages:

Every segment starts with a short header that sets the stage before the first shot: Location (a scene chip), Time, Weather, the Opening frame (what the first frame shows), Set dressing (what is in the room, and any background people) and Props (the objects the segment uses).

SceneMixer, The Segment Header, Field by Field (read 2026-10-13)

The shot seconds in the storyboard add up to the segment length, so editing them changes it.
