thats an H.264 High profile video in an mp4 container Im not sure what you are asking it sounds like you are trying to grab frames maybe from the file itself and not from the screen if you are doing so you have to grab an I Frame....those are the only ones that contain all of the picture info the other frames are encoded as delta changes to the previous frame until the next I frame (yes thats a tad simplified i know about B frames but they arent gonna help)

if you are having trouble playing the video it is likely because your codec is not fully h.264 compliant (many including apple Ipads) cant play the HIGH Profile encode you have to use MAIN or BASELINE

I think the HIGH profile is technically called H.264 Level 10

i can play the video, i just cant grab thumbs correctly using software that i normally use to do it.
