EE4 Media Player Comparison 10/3/2010: Video playback comparison in Windows Media Player 12, VLC Media Player, RealPlayer SP, and QuickTime on three computers. Images are TIFF screen captures of a source file and encoded output from Microsoft Expression Encoder 4 Pro. Rankings represent relative image quality from best (1) to worst (4) for each file. Windows Media Player 12 produced the best quality video. There was no noticeable difference among the source file, EE4 mp4 output, and EE4 wmv output. Video playback in VLC Media Player 1.1.4 on a computer running 32-bit Vista Professional was equivalent to WMP12. However, images were more pale on a second computer running 32-bit Vista Home Premium. There was no noticeable difference among the source file, EE4 mp4 output, and EE4 wmv output on each computer. The H.264 mp4 source video and EE4 output file were pale and washed out when viewed in RealPlayer SP 1.1.3. However, image quality of the EE4 wmv file was better and equivalent to playback in WMP12. Images also appeared pale and washed out in QuickTime. There was no noticeable difference between the source video and EE4 mp4 output. Image quality can be improved in QuickTime Pro by changing transparency to "Straight Alpha." Each media player produced comparable image quality for source video and EE4 output (except Realplayer SP, where wmv output was better). The pale, washed out appearance of H.264 mp4 video is likely a result of media player codecs and color management. Color and luminance shift may not be intrinsic to the H.264 encoding process, or some media players effectively accommodate for it. Click the "Next" button to view other slides in the set. EE4 Media Player Image Quality 10/3/2010: Video playback comparison in Windows Media Player 12, VLC Media Player, RealPlayer SP, and QuickTime on three computers. Images are TIFF screen captures representing a source file and encoded output from Microsoft Expression Encoder 4 Pro. Rankings represent relative image quality from best (1) to worst (4). Luminance waveform charts were generated by Adobe Premiere Pro CS3. The highest quality video was produced by Windows Media Player 12, VLC Media Player 1.1.4 on a Vista-32-Pro computer, and Realplayer SP (VC-1 wmv files only). H.264 mp4 playback appeared pale and washed out in RealPlayer SP, QuickTime, and QuickTime Pro (default settings). The same video has different color and luminance characteristics when viewed in different media players. Therefore the pale, washed out appearance of H.264 mp4 video is likely a result of player-specific codecs and color management. Click the "Prev" or "Next" buttons to view other slides in the set.
