the delay on the motion detection loop slowed it down too much to the point that it falls too far behind live. I removed the delay and re-introduced the frame gap so all frames in the video files need to be decoded. post command and event timers are now seperate but still tied to a single thread so they can still be synced. fixed an issued that cuased several thmubnails to not generate. added more log lines the aid with debugging.
