5Using the models, not reading about them
Release notes such as “Seedance 2.0” matter once a pipeline runs the models; SceneMixer's guides describe how it does:
Seedance 2.0 (ByteDance's video model family) is one of the strongest engines for vertical short drama in 2026.
SceneMixer, Seedance 2.0 in a Real Short-Drama Pipeline (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).
