Еxtract scene change info from a video file
14 avril 2017, par Ray P.Is there a way to extract scene change information from a video file using XVid in Python ? For example : I have an .mkv file, and I need to get a .log scene change file (Xvid 2nd pass stat file) to use for subtitles timing. SCXvid can create such files, but I’d like to do this in Python if possible.
The reason why I need this is because the only way to do it on Linux is to use SCXvid-standalone which requires y4m files, and I need to use files in their original format.

Detect scene change on part of the frame
16 juin 2021, par user18130814200115I have a video file of an online lecture cosisting of a slideshow with audio in the background.

I want to save images of each slide as well as the timestamp of that slide.
I do this using the scene and metadata filters :

ffmpeg -i week-01.mp4 -filter_complex "select='gt(scene,0.011)',metadata=print:file=frames/time.txt" -vsync vfr frames/img%03d.jpg



This works fine exept for one thing, there is a timer onscreen on the right in the video file.
If i set the thershold small enough to pick up all the slide changes, it also picks up the timer changes.


So here is my question, Can I ask ffmpeg to :


- 

- analize part of the frame (only the right side till roughly 75% to the left).
- Then, on detecting a scene change in this area, save the entire frame and the timestamp.






I though of making a script that


- 

- crops the video and saves it alongside the origional
- analize the cropped video for scene changes and save the timestamps
- extract the frames from the origional video using the timestamps








Is there a better/faster/shorter way to do this ?
Thanks in advance !
