I was typing a reply to my post commenting on the same issue, Ed's script is 
quite useful, but but I did resize the the frames down to something suitable for 
mobile, my original was TV capture at 1920x1080, mp4 was about 21MB/min, vs. 
1500k/min at 720x480.

Even on a tablet that looks acceptable for many things, and until I trade my 
tf300 for a tf700 and get new glasses, it will do.
