7Using the models, not reading about them
Release notes such as “Sora” matter once a pipeline runs the models; SceneMixer's guides describe how it does:
Dubbing replaces the audio of a finished clip; the picture was generated for a different line, so mouth shapes, pauses and shot length all belong to the original language. Native-language generation gives the video model the line in the target language before it renders the shot, so the performance, the pacing and the cut points are built for that language.

The second trim replaces the first trimmed version; the generated clip stays in Version History.
