सीन चेंज डिटेक्टर
फ़्रेम अंतर के आधार पर वीडियो में सीन कट का पता लगाएँ और उनके टाइमकोड सूचीबद्ध करें, ताकि एडिट, चैप्टर लिस्ट या क्लिप एक्सपोर्ट असली सीमाओं से शुरू हो सके।

How the Scene Change Detector works
- Add the video file; it is read locally, so length is limited by your device rather than an upload cap.
- Set sensitivity — low finds hard cuts, high also picks up fades and flash frames.
- Set a minimum scene length to suppress duplicate detections around a single transition.
- Detect scenes, then read the timecode list — each entry shows a thumbnail and a Go to button — or switch to CSV and copy or download the result.
The method
Detection samples frames at a rate tied to sensitivity, compares each sample to the one before it, and flags the moment the difference between them exceeds a threshold, which is what a hard cut looks like numerically.
cut when mean absolute frame difference > threshold, held for the minimum scene length
A fade produces a run of moderate differences rather than one spike, which is why it needs a lower threshold and grouping to be caught as one transition.
FAQ
Why does a camera flash register as a cut?
Because the frames genuinely differ enormously for one frame. A minimum scene length collapses these single-frame spikes, which is what that setting is for.
Will it find soft transitions?
Cross-fades and wipes are gradual, so raise sensitivity — at the cost of false positives on fast motion and lighting changes.
Can I see what each detected scene looks like?
Yes — the timecode list shows a thumbnail from the start of every scene, and its Go to button jumps the video preview there so you can check it without scrubbing manually.
Can I export the results?
Yes — copy the timecode list or CSV to your clipboard, or download it as a .txt or .csv file.
Is the video uploaded?
No. Frames are read in the browser, which is also why very long files are slow.

Scene Change Detector gives you the boundaries and a set of honest caveats — flashes and fast motion look like cuts to any frame-difference method, on this tool or any other.
