How to easily reinstall Windows How to uninstall programs in Windows 10 with system tools. How to install custom themes on Windows VC-1 supports three profiles: Simple, Main, and Advanced. The Simple and Main profiles have been complete for several years, and existing implementations such as WMV 9 have long supported the creation and playback of content using these profiles, as well as an early implementation of the Advanced profile.
The completion of the Advanced profile and consequent standardization of all profiles in VC-1 represents the final step in a comprehensive specification that delivers high definition content—either interlaced or progressive—across any medium and to any capable device. It supports Simple, Main, and Advanced profiles. These profiles support a wide range of bit rates, from high-definition content at one-half to one-third the bit rate of MPEG-2, to low-bit-rate Internet video delivered over a dial-up modem.
This codec also supports professional-quality downloadable video with two-pass and variable bit rate VBR encoding. Windows Media Video 9 is already supported by a wide variety of players and devices. Content creators can use this profile to deliver either progressive or interlaced content at data rates as low as one-third that of the MPEG-2 codec—with the same quality as MPEG In the past, interlaced video content was always de-interlaced before encoding with the Windows Media Video codec.
Now, encoding applications such as Windows Media 9 Series, and third-party encoding solutions can support compression of interlaced content without first converting it to progressive content.
Maintaining interlacing in an encoded file is important if the content is ever rendered on an interlaced display, such as a television. Transport independence also enables the delivery of Windows Media Video 9 Advanced Profile over systems that are not Windows Media-based, such as standards-based broadcast infrastructures through native MPEG-2 transport streams , wireless infrastructures using real-time transfer protocol [RTP] , or even DVDs.
The following table compares Windows Media Video 9 Advanced Profile to competing compression technology. The Windows Media Video 9 Screen codec is optimized for compressing sequential screen shots and highly static video that is captured from the computer display, which makes it ideal for delivering demos or demonstrating computer use for training. The codec takes advantage of the typical image simplicity and relative lack of motion to achieve a very high compression ratio.
During the encoding process, the codec automatically switches between lossy and lossless encoding modes, depending on the complexity of the video data. For complex data, the lossless mode preserves an exact copy of the data. For less complex data, the lossy mode discards some data to achieve a higher compression ratio.
By automatically switching between these two modes, the codec maintains video quality while maximizing compression. Overall, the Windows Media Video 9 Screen codec delivers better handling of bitmap images and screen motion, even on relatively modest CPUs.
Note] Dolby AC-3 streams are limited to the three highest rates in this list. Valid values are in the range 1 mono to 8 7. If this attribute is not set, the default value is 2 stereo. If specified, the value must be consistent with the number of audio channels.
If the attribute is not set, the decoder uses a default channel mask, based on the number of channels. The output sample rate must be identical to the input sample rate. The decoder cannot change the sampling rate of the stream. Required for PCM output. Not needed for digital output.
If the input type is mono, stereo, or dual-mono all without LFE channel , the only valid value is 2, for stereo output. Otherwise, the value can be: 2 for stereo downmix 6 for 5. Required for PCM output if the number of channels is greater than 2.
The value must be: 0x3 for stereo output 0x3F for 5. Optional for PCM output. Not needed for the digital output subtypes. Specifies whether a 2-channel Dolby audio stream is encoded as stereo or dual-mono.
