Generate an Assembly Cut From 4K Footage Automatically
The assembly cut is the least creative edit you'll ever make and the most time-consuming: pull selects, drop them in order, delete obvious dead air. AutoEditor generates it for you — it ingests the full 4K source, identifies the strongest segments, drops the dead weight, and returns a structured assembly you'd normally spend an afternoon building.

Tool To Generate Assembly Cut From 4k Footage Automatically FAQ
What's the difference between an assembly cut and what AutoEditor returns?
A manual assembly is chronological selects. AutoEditor's pass is already shaped — strongest hook moved to the front, dead air removed, weak segments cut — so what you get back is closer to a rough cut than a raw assembly.
Can it handle multi-GB 4K files?
Yes — upload is the only heavy step and it runs from your browser. All processing happens server-side, so 4K ProRes or hours of footage don't tax your machine.
Can I pull the assembly into Premiere or DaVinci?
Yes — export the edit decisions as XML/EDL and open the cut in your NLE for finishing, or download the rendered edit directly.
What formats does it accept?
MP4, MOV, WebM and most common formats — including high-bitrate 4K sources.
