One search per line, written for that line
Each beat gets its own search, written from what the line is about and what should be on screen — not a keyword pulled out of the sentence. Lines about a specific person, place or year are searched as that person, place or year.
Watched, not just matched
Candidates are downloaded and looked at frame by frame. The engine keeps the moment of the clip that shows the subject and rejects anything that is a diagram, a talking head, a watermarked upload or a still pretending to be footage.
Trimmed to the voice
Each clip is cut to the exact length of its line in your voiceover, so the picture changes when the sentence does. The whole edit arrives as a timeline you can change in the browser.
