FAQ
Can I monetise Shorts made with AI video?
YouTube allows AI-assisted content but requires disclosure when realistic content is synthetically generated, and it rewards original, meaningful work over mass-produced repetition. Use the altered-content disclosure at upload.
What format do YouTube Shorts need?
Vertical 9:16, up to 3 minutes. Generate 9:16 clips and stitch several together for a longer Short.
Can I use these clips as B-roll in a long-form video?
Yes — clips download as clean MP4s with commercial rights, so they drop straight into a long-form edit.
What resolution is the output?
Clips are delivered as MP4 at up to 4K, which is more than enough for Shorts.
