Haha no problem! To be honest I totally forgot I did this.. glad to help,
hope the ffmpeg params haven't changed around too much : )

Thank you so much. I've been looking into doing this with video editing.
But that is labor intensive and inefficent even if automated. Github is so
lovely. Thanka to the effort of others we do not need to reinvent the wheel
every day!

Yeah I have no idea what I'm doing at all. But that's fine! This probably did work with python 2.3 or something. And all the bones to make it go brrr are there. Hell it probably works now. But I'm just making my first steps into learning coding. So this will be a good benchmark of my own progression through the learning process.
