I've used this tool for breaking up movie trailers and old Vines. I really didn't like the output quality.
I ended up using optical flow and key frame information instead.
- Breakthrough 7y agoHi genp; Just curious, what didn't you like about the output quality? What version of PySceneDetect were you using? The latest version (v0.5.x) uses ffmpeg instead of mkvmerge for output by default now, which produces significantly more accurate and higher quality output than before. That being said, you are correct in that optical flow and keyframe information is currently not being used during the detection phase. There are several proposals to incorporate this into a future release, however, along with several other techniques: - histogram analysis - edge detection - background subtraction - automatic or dynamic threshold detection Thanks for your feedback!
