4A pipeline on current models

Release notes such as “Kling AI” matter once a pipeline runs the models; SceneMixer's guides describe how it does:

Lip sync is the default: the picture stays frame for frame, every line is voiced again and the mouths are moved to match; the original ambience is dropped.

SceneMixer, Lip Sync or Re-perform: Choosing How to Redub a Clip (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).
