How SceneDub gets clips
SceneDub keeps YouTube browsing separate from playable dubbing. YouTube is used for official search and embeds. Dubbing scenes use reviewed, reusable media with transcript timing, attribution, and a separate backing track.
Playable dubbing scenes
SceneDub's current dubbing pages use prepared local scene assets: a short video file, a dialogue-free backing track, a thumbnail, timed transcript lines, source attribution, and a license record. That is what lets the browser sync your recording and render a finished dub.
YouTube discovery
The YouTube tool searches public, embeddable short videos through the official YouTube Data API and plays selected results in the official embedded player. Those results are reference material, not downloadable source media and not automatic dubbing inventory.
Captions and transcripts
SceneDub does not scrape YouTube captions. Public YouTube results can be browsed through the player, but a YouTube caption track is not treated as a free transcript source for arbitrary videos. Playable scenes need reviewed timing data and reusable rights.
Catalog growth
The scalable path is a rights-cleared catalog: Creative Commons, public domain, creator-licensed, partner-supplied, or original clips with explicit permission to prepare short practice scenes and dialogue-free backing audio.
What happens today
The playable scene library points to local URLs under /clips. The YouTube meme finder points to youtube-nocookie.com/embed and does not download or alter the video.
Why this matters
Dubbing needs more than a video URL. It needs permission, exact line timing, and a backing track that keeps the scene audio while removing the original dialogue. A normal YouTube embed cannot provide that workflow.
