ffmpeg has a scene detection filter which can be used to analyze the scene changes in a video,
i created three scripts to automate scene detection using ffmpeg
scene-detect - analyzes the video and outputs the scene time changes to a text file
scene-time - converts the output of scene-detect to a csv file with the start point of the scene and the duration
scene-cut - takes the csv file created scene-time loops over the start points and creates clips for the duration of each scene change
We can use a Makefile to automate ffmpeg scene detection instead of running the scene-detect, scene-time and scene-detect scripts manually
Makefiles and ffmpeg scene detection made easy
You just need to install the scripts listed above put the Makefile in the same directory as the video
and then run
you can also press tab to autocomplete input and then = and the name of the video to process
you can also perform scene detection on a range in the video for example from 5 to 10 minutes
as well as change threshold used to determine the scene change
the scene detection output video clips filenames will contain the input video filename
and the time of the start of the clip and the duration
so if you processed a video called big-buck-bunny.mp4
the scene detection video clip filenames would look like this
big-buck-bunny-[00:00:00-00:00:02].mp4
big-buck-bunny-[00:00:02-00:00:04].mp4
big-buck-bunny-[00:00:04-00:00:06].mp4
make clean
will prompt you to delete the ffmpeg scene detection text files and all the created clips
except the original video file and Makefile
MakeFile
scene-detect
scene-time
scene-cut
the scripts are part of a collection of ffmpeg shell scripts for simple editing tasks
