These are the characteristics of the clips recorded by the Panasonic camcorder: Format profile: High@L4.2 Format settings, CABAC: Yes Format settings, ReFrames: 2 frames Format settings, GOP: M=3, N=24 Bit rate: 23.8 Mbps Maximum bit rate: 25.0 Mbps Width: 1 920 pixels Height: 1 080 pixels Frame rate: 50.000 fps So, it uses only two reference frames, but it has twice as many fps, and the bitrate is accordingly higher. This is, apparently, quite beyond the capabilities of the decoder: the playback is smooth, but about half the actual speed.
