“-vcodec mpeg4 -qscale 2” reduces the file size by a factor of 50 and can be opened in my downstream analysis Ethovision. It will take a week or so to run some real experiments and see if the video quality is good enough, but it looks great and I’m optimistic that this solved the problem. Thanks for your suggestions! They really made a difference.
