FYI, it's sped up because they only take 4-5 frame per seconds. The heat shield separation is at +278s (278 seconds after atmospheric entry) and the touchdown is at +416s. That's a difference of 138 seconds, which in the video takes about 38 sec (0:15 - 0:53), so the play-back speed up is about a factor of 3.6.
I know that a HD version will eventually make its way from Mars to Earth, but I have read in a couple of places that the Descent Imager only operates at 5 fps. That could have been a mis-statement though.
I (or perhaps what I was reading) may have had the descent cam's stats confused with the high-quality mast cam, which won't be deployed until next week. Still exciting, though.
