Also, H.264's quality advantage is typically more evident at low bitrates.įor audio, MediaCoder offers WMA7, WMA8 and WMA9, with the latter being version 9.2, by default. However, H.264 is more consistently able to yield better picture quality because it supports multiple reference frames and reference B-frames, etc.
While Windows Media Video 7 and 8 codecs were comparable to MPEG-4 ASP in terms of visual quality, Windows Media Video 9 seems to be regarded as comparable to H.264 Main and High Profile. In principle at least, MediaCoder offers WMV7, WMV8 and WMV9 on the video tab.
One advantage of a WMV file is that there are more consumer devices that suit it, although, its proprietary nature fails it, it is not MPEG4 compatible and there are not many options available to tweak. Although WMV is generally packed into the ASF container format, with the WMV extension, they can also be put into the MKV or AVI containers. Windows Media formats (WMV and WMA) are proprietary (Microsoft).
