I was able to find this thread on cutting a specific portion out of a file. It's not very useful since I'm looking to do the exact opposite which is to remove the selected portion of the video.
This user's solution for extracting a part without re-encoding works pretty well. Can I do something similar to remove a selection portion instead?
I prefer not having to re-encode, but I'm fine either way so any solution would do.
concat
demuxer withinpoint
andoutpoint
as described in the following post. It is done without re-encoding. Without re-encoding has some limitations (it cuts only in key frames, and it's not always working).
