Hey guys!

So, I recently decided to make some online collaboration videos. The problem is that I don't know what is the whole procedure for recording and making such of thing. I don't know whether everyone is filming his part and then we just unite the videos or there are some other ways? Can you help me with step-by-step program and maybe with a good software for that? Thanks!

Oh, I didn't know where is the right place for a thread like this, so sorry if I made it in wrong place.
