Common Questions

Frequently asked

What does Seedance 2.5 Video Edit do?

It edits an existing video from a text prompt — the input video drives subject identity, composition, and motion, while the prompt controls lighting, style, weather, environment, or specific elements.

Does it preserve the original video's motion?

Yes — the reference video drives composition and motion; the prompt only controls what's rewritten (lighting, style, environment, specific elements).

How much does it cost?

Price scales with the selected `resolution` (480p/720p/1080p/4K), billed on the combined duration of the input video plus the generated output at 65% of the base per-second rate for that tier — $0.1105–$1.105/sec (480p–4K). See the pricing table below for exact per-resolution rates.

How long can the input video be?

Videos longer than 30 seconds are automatically trimmed to 30 seconds before editing.

Can I preserve the original audio?

Yes — set `generate_audio` to `false` to keep the input video's original audio instead of generating new audio.
