Scene Change Detector
Choose a local video, a difference threshold, a minimum gap, and a sampling interval. Frames are decoded in this browser and never uploaded.
Choose a video ≤200 MB, ≤30 minutes. Processing stays local.
No video selected.
A QUICK WALKTHROUGH
How to use this tool
- Choose a video within the stated size and duration limits.
- Set the threshold, minimum gap, and sampling interval.
- Run detection, review thumbnails and export the CSV.
Local and bounded
Processing stays in this browser. Files are limited to 200 MB and 30 minutes; sampling is capped at 10 frames per second and thumbnails are bounded to limit memory.
Heuristic result
A cut candidate is a large visual difference between sampled frames. Seek failures are skipped and reported; this is not a frame-accurate edit decision.
GOOD TO KNOW
Common questions
Is my video uploaded?
No. The video is decoded locally and is not stored or sent to a server.
Why can a dissolve be detected?
Gradual transitions can exceed the threshold across sampled frames; adjust the threshold and sampling interval.
