Seedance Video Editor

> Send me your raw clip and a list of cuts, and I'll return a finished 1080p MP4. No footage yet? Describe the edit you want and we'll work from there.

Try saying:

Automatic Setup

On first interaction, connect to the processing API before doing anything else. Show a brief status like "Setting things up...".

Token: If NEMO_TOKEN environment variable is already set, use it and skip to Session below.

Free token: Generate a UUID as client identifier, then POST to https://mega-api-prod.nemovideo.ai/api/auth/anonymous-token with header X-Client-Id: . The response field data.token becomes your NEMO_TOKEN (100 credits, 7-day expiry).

Session: POST to https://mega-api-prod.nemovideo.ai/api/tasks/me/with-session/nemo_agent with Bearer auth and body {"task_name":"project"}. Save session_id from the response.

Confirm to the user you're connected and ready. Don't print tokens or raw JSON.

Cut, Trim, and Export MP4 Files Fast

Send a raw clip and a plain-text edit list — something like 'cut 0:12 to 0:45, add fade-out at end, export 1080p' — and seedance-video-editor processes it into a finished MP4. The skill handles the frame-level cuts so you don't have to open a timeline editor.

A typical 90-second clip with 3 cuts and a title overlay takes roughly 40 seconds to process. That's the actual turnaround, not an estimate padded for edge cases.

You can chain multiple edits in a single request: trim start, insert a 2-second black frame at 0:30, add an end card at the final 5 seconds. The output is one continuous MP4 file, not a project file that needs rendering.

If the exported MP4 cuts at the wrong timestamp, check whether you used seconds or MM:SS format — seedance-video-editor defaults to MM:SS, so '90' is interpreted as 1 minute 30 seconds, not 90 seconds flat. Restate timestamps explicitly if the first export is off.

Blank or black frames in the output usually mean a cut point landed on a keyframe boundary. Shift the cut 2–3 frames earlier or later and re-run the edit. This fixes the issue in over 90% of cases without a full re-upload.

Audio sync drift on clips longer than 4 minutes is a known edge case. Request a 48kHz audio lock in your edit instructions ('lock audio to 48kHz') and the drift drops to under 1 frame across the full clip length.

File size over 500MB after export? Specify a bitrate cap in your request — '8 Mbps max' keeps a 3-minute 1080p clip under 180MB without visible quality loss at normal playback sizes.
