I tried a whole bunch but then opening the recorded files in quicktime the codec mostly ended up being H264.
I was hoping to use the recorded videos to looped them in PALINDROME mode. But playing these videos back in reverse causes a stutter, which I believe is due to the codec.

I have not worked on this for a while. But at this point I would use the HAP codec with which I had good results.
