Frequently Asked Questions
What is the best starting point for a talking-head edit?
Start with `list_capabilities`, then use `edit_footage` for silence removal, dynamic zooms, color correction, and audio mastering before you add motion graphics.
Can it turn a transcript into captions or motion graphics?
Yes. `transcribe_video` gives you word-level timing, and `create_animations` uses those cues to build overlays like counters, quotes, lists, and flowcharts.
How do I finish the edit with B-roll and overlays?
Use `finalize_video` after the base edit and animation pass. That is the step that assembles the final export with B-roll clips, overlays, and the chosen output encoding.
Does it support multi-camera footage?
Yes. `edit_footage` supports one or two cameras with automatic audio sync, so it works for simple interviews as well as single-camera content.
