Format: ACV0 Media, 640x480, Millions, AAC (Protected), 2 channels, 44100 HZ
FPS: 29.97
Data Size: 254.9 MB
Data Rate: 1560.66 kbit/s
Current Size: 640x480 (Actual)
Apple uses 1000*1000 as a MB (and not the customary 1024*1024), so the
reported size is not quite accurate. But I don't expect it to make a
difference.
