Is each frame shape generated or cropped?
Pexo is the one vendor that says: each of its three shapes is generated fresh, framed for that screen rather than cropped. Filmora, an editor, switches a project to 9:16. The others do not say. From 2 source pages, read 2026-09-25; no maker pays to be listed.

2What it means for delivery
A cropped vertical version of a landscape shot keeps the centre and loses the sides, which can cut characters out of a two-shot. Generating each shape separately avoids that at the cost of a second generation, and the two versions will not match frame for frame, because each is a separate take.

3What a generator delivers
For a delivery question like “Is each frame shape generated or cropped”, SceneMixer states the following about what it produces:
16:9 landscape (SceneMixer's default) and 9:16 vertical (the usual short-drama frame), chosen per project.
SceneMixer, Seedance 2.0 in a Real Short-Drama Pipeline — “Which aspect ratios does the pipeline generate?” (read 2026-10-13)
Typically 60–120 seconds, always 9:16 vertical, ending on a hook. SceneMixer's episode outlines are generated with that pacing, and setting a project to 9:16 makes every segment vertical (the default is 16:9).
