Manufacturer is GoPro. Camera model is HD Hero, actually HD Helmet Hero but the helmet just stands for helmet straps. Video format is h264 mp4 and audio format aac according to ffmpeg -i:
Stream #0.0(eng): Video: h264, yuv420p, 1280x720 [PAR 1:1 DAR 16:9], 59.94 tbr, 90k tbn, 119.88 tbc
Stream #0.1(eng): Audio: aac, 48000 Hz, 2 channels, s16
kdenlive build from svn against ffmpeg from git shows the h264 videos without problems.
Only problems I can think are using p60 video in slow motion mode for p30 output without loosing information and with a sound track streched to match the video.
Don't know how to do that yet.
