capture frame

sorry, I made snapshots of a movie, but I can't see the difference between "capture frame original size (P)" and "capture frame what you see, (shift+P)". I got the same identical snapshot, even if I . where 's the difference, please?

change the size of the movie window and you'll see the difference !

for instance, when I play a 512*384 movie full screen (res. 1152*864)
capture using P --> picture is 512*384 (original size)
capture using shift+P --> picture is 1152*864 (size shown on screen when playing)

Did that.

Didn't work.

Full screen movies still capture to small 3" x 5" size on screen regardless of whether "P" or "Shift + P" is used.
