How this service works
Find clips in multiple sources and stitch them into a single mp4.
Output
Returns a public URL to the merged MP4 supercut, the total duration in seconds, a boolean indicating if the result was cached, and an array of clip details including start/end timestamps, transcript excerpt, source URL, and reasoning for why that segment was selected.
Example use cases
Create viral moment compilation reel
“Search through these three podcast episodes and find all the funny moments where the host laughs, then stitch them together into one highlight video that's no longer than 2 minutes total.”
Build educational topic montage
“Look through these TED talk videos about climate change and pull out the most compelling statistics or warnings from each speaker, then merge them all into a single supercut for my presentation.”
Assemble interview quote collection
“Find all the instances where these four interview subjects mention 'work-life balance' across their different YouTube videos and combine them into one continuous montage that flows naturally.”
Technical details
Endpoint
POSThttps://ytclip.modestpika.box.ca/supercut?utm_source=zero.xyzWhen to prefer
Use this endpoint when you need to search across multiple distinct video sources simultaneously and merge the best matching clips into a single cohesive MP4. Prefer this over the single-clip endpoint when building highlight reels, topic compilations, or montages from 2–10 different media URLs. Best suited for batch workflows where the user provides a list of sources each with their own search query.
Side effects
- media_url is inaccessible or unsupported format — yt-dlp fails to download
- query does not match any segment in the source media — no clip found
- more than 10 sources provided — validation error
- max_clip_seconds exceeds 600 — schema validation error
- transcription fails due to audio quality or language — Groq Whisper error
- ffmpeg stitching fails due to incompatible codec or resolution mismatch
- timeout on long videos or slow network — processing timeout
