I made a screen recording, but then accidentally left it recording overnight for an extra 6 hours. In total I think it’s around 9 hours – and the file has hit 15GB.
Luckily it managed to save to the desktop, but I’m struggling to open it to trim it down.
I’m thinking the best way it to split the file into ~30 smaller files. I could then reassemble the desired ones.
Equally I’m fairly confident of where the useful content ends – around the 2:30 mark. I could calculate it more accurately if needed.
Could I do either of these things with a tool which doesn’t load the entire video into memory? I’ve used ffmpeg on Ubuntu before but I do not know if it can do something like this.
