After having searched here & there I couldn't find an alternative to a Win application namely Solveigmm Video Splitter. My requirement isnt a clone of this application rather the way I use it!
Now I use it something like this I open up an hour long video & being an English teacher I mark it at various durations (on average 10+) & then those parts are merged to result another short clip...
Something close to this is Openshot in Linux however after every duration I had to drag it to another track & then join it, pretty intensive & repetitive.
Now am open to cli options as well e.g is there a way to mark at various durations & the start time & the end time being saved to a text file then via terminal & some bas I input this to ffmpeg where it make various & then joins them?
