I have a few videos that I'd like to edit in either Final Cut Pro or in Adobe After Effect but since those two programs don't support .MKV files, I'm trying to get them converted. So far I've looked around and found a few paid programs that were recommended but I'm not trying to spend any money on those converters. Instead I found HandBrake which gets the job done but is quite slow. So instead of converting the entire file, I was thinking of cutting out the parts I don't need. This would reduce the overall size and length of the file and therefore, save me a lot of time. Only problem is, is I don't know where I can get a free program that does this. I could just be overthinking this and taking the long route so if anyone has any other ideas of how I can edit .MKV files, please let me know.
