I will post my results in a bit, if I forgot someone remind me
But I figured out a way to get around the 1000 frame issue, I use "sort -V"
I am working on speeding up the video generation, It seems mencoder or libavc only uses 1 core for mpeg4 encoding, even with threads=4 passed as an option, I see the threads in htop, but cpu usage isnt maxed out
I'll perhaps try h264
Or better yet, rewrite the script to create all the sorted.lists from the monitors, and then use bash parallel to spawn off as many mencoder threads as we have cores on the box
I do not think it's possible to speed up the find command.

I have commented a lot of the original code out for my testing
I changed my location for events to fit Ubuntu style
I changed mtime to 3, for 3 days rather than 1 day
I changed the sort command and added -V for --version-sort
I changed my camera fps to 15, and added threads=4
