Adding two high quality export profiles: Mpeg2 I-frame only, with highest FFmpeg quality and H264 with FFmpeg constant quality of one. Per http://itbroadcastanddigitalcinema.com/ffmpeg_howto.html. I chose mp2 sound for Mpeg2 and aac for H264. H264 PAR is broken for an unknown reason. Tested these two profiles with XDcam, HDV and DV footage from our page http://www.kdenlive.org/contribution-manual/footage
