Na dpreview píšu:

"The movies are recorded in QuickTime MJPEG (.mov) format and at the highest quality settings work out at a whopping 5.1 MB/sec. The maximum length of a movie recording is 15min if you don't run out of space on your memory card before that. You'll fit around 10 minutes of footage onto a 4GB card."

takže to bohužiaľ nebude chyba ale vlastnosť.
