Comment (by cehoyos): Replying to [comment:3 zjacobs]: > According to my research and actual use, it may be "worse quality" than libx264 but it's faster. Additionally, it's hard to notice much of a difference when transcoding for mobile devices anyway. > > http://www.anandtech.com/show/5771/the-intel-ivy-bridge-core-i7-3770k- review/21 I did not find any comparison between x264 and QuickSync in this article. Did I miss it? > http://forum.doom9.org/showthread.php?t=166958 It is claimed here that x264 Ultrafast is faster than QuickSync. http://www.compression.ru/video/codec_comparison/h264_2012/mpeg4_avc_h264_video_codecs_comparison.pdf seems to indicate to me that QuickSync has no advantages over x264 but maybe your results are different? -- Ticket URL: <https://ffmpeg.org/trac/ffmpeg/ticket/2591#comment:4> FFmpeg <http://ffmpeg.org> FFmpeg issue tracker _______________________________________________ FFmpeg-trac mailing list FFmpeg-trac@avcodec.org http://avcodec.org/mailman/listinfo/ffmpeg-trac
