YouTube questions, answered
Can one video become both a Short and a long-form upload?+
Yes — that's the core workflow. Edit once, publish horizontal, and let the AI extract vertical Shorts.
Do you generate YouTube chapters?+
Yes — chapter timestamps are inferred from the transcript and inserted into your video description.
What about copyright-safe B-roll?+
B-roll is sourced from licensed stock libraries with commercial-use rights, so monetization stays intact.
