First remix video

The remix track is the spot for discovering a hook in an existing video and reworking it. It doesn’t write a new scenario; it lays cuts, subtitles, and BGM on top of the source timeline. If you use the generative track, go to first-generative-video.

1) Attach the source URL

Attach the source URL in natural language.

A URL attachment enters the remix track (remix-flow-orchestrator). Signals like “remix,” “YouTube clip,” “trim this video,” “cut this part” also go to remix.

2) The license gate blocks first

This is the spot you hit first in remix. If the source has no license label, it refuses to proceed. It’s the spot that blocks copyright accidents at the code level.

What the gate requires:

License label: which license the source is under, stated
Fair Use of 30% or less: a limit on the amount of the source used
At least three transformation duties: at least three transformations like cut, subtitle, zoom, BGM, SFX

To proceed with a source whose license is unclear, the user has to explicitly accept responsibility. It’s the spot where responsibility acceptance is planted in license_responsibility.json. This forcibly opens the gate, meaning the copyright responsibility is on the user. It isn’t a spot to use lightly.

3) Gate A — collection and analysis

Once you clear the gate, source-analyst downloads the source with yt-dlp, transcribes with Whisper, and detects the hook. It finds the strongest spot in the source (a laugh point, a twist, a memorable line). In preview mode it downloads at 480p and runs with a small Whisper model, fast.

Normal screen: transcription finishes and hook candidates are set. Pick which spot to use, or say “redo the hook” to find another.

4) Gate B — auto-editing

remix-editor cuts the chosen spot, converts it to 9:16, and composites subtitles, BGM, and SFX in one pass. ffmpeg single-pass makes it in one go rather than per-scene clips.

Normal screen: the edited video draft is out. Partial edits like “different BGM” and “redo the hook” work.

5) Speed

Remix is faster than generative. About 5–15 minutes per episode. It’s the spot that reworks a source rather than generating images, so with no Codex calls it’s light.

6) The source is attributed automatically

A remix video auto-attributes the source per the license policy. The source is planted in the publish metadata, reducing copyright disputes on upload.

Once the video draft is out, go to publish, the spot for making publish metadata and uploading it yourself.
