Description from YT:
Latest downlinked images from Mars Descent Imager (MARDI) as of the morning of August 19th 2012. Audio from control room is roughly matched to the video. The images have been assembled into a video at approximately 5 frames a second (matching the rate at which they were captured). Not all images have been received from Curiosity, so this video is incomplete and slightly choppy. However it does show the entire sequence from backshell separation to wheel touchdown.
