How to use scene change candidate detector
Select a local file if requested, or enter values and review them. Choose Process in browser, review the output and download it before leaving the page. If the browser cannot decode a file, the tool reports the limitation rather than uploading it elsewhere.
Method and accuracy
Classical threshold analysis only; misses short cuts between samples and is not AI scene understanding. Processing occurs within device and browser limits; actual player compatibility can differ by format. No generated captions, speech transcription or AI enhancements are offered.
