Video Device Conformance Templates
[The feature associated with this page, Windows Media Format 11 SDK, is a legacy feature. It has been superseded by Source Reader and Sink Writer. Source Reader and Sink Writer have been optimized for Windows 10 and Windows 11. Microsoft strongly recommends that new code use Source Reader and Sink Writer instead of Windows Media Format 11 SDK, when possible. Microsoft suggests that existing code that uses the legacy APIs be rewritten to use the new APIs if possible.]
The following tables list the device conformance templates and associated parameters for the Windows Media Video 9 codec.
Simple Profile, Low Level
| Parameter | Value |
|---|---|
| Template string | "SP@LL" |

| Maximum resolution | 176 x 144 |
| Maximum frame rate | 15 fps |
| Maximum bit rate | 96 Kbps |
| Maximum buffer size (in 16384-bit units) | 20 (about 3.4 seconds at maximum bit rate) |
| Interlaced Encoding | No |
Simple Profile, Medium Level
| Parameter | Value |
|---|---|
| Template string | "SP@ML" |
| Appropriate devices | Handheld computers and Personal data assistantsHigh-end wireless handsets |
| Maximum resolution | 352 x 288 |
| Maximum frame rate | 15 fps @ 352 x 28824 fps @ 320 x 240 |
| Maximum bit rate | 384 Kbps |
| Maximum buffer size (in 16384-bit units) | 77 (about 3.3 seconds at maximum bit rate) |
| Interlaced Encoding | No |
Generic Simple Profile
A stream that complies with the algorithmic limitations of the simple profile, but does not fit into one of the level specifications, will be assigned "SP" as its device conformance template string.
Main Profile, Low Level
| Parameter | Value |
|---|---|
| Template string | "MP@LL" |

| Maximum resolution | 352 x 288 |
| Maximum frame rate | 30 fps |
| Maximum bit rate | 2 Mbps |
| Maximum buffer size (in 16384-bit units) | 306 (about 2.5 seconds at maximum bit rate) |
| Interlaced Encoding | No |

| Maximum bit rate | 10 Mbps |
| Maximum buffer size (in 16384-bit units) | 611 (about 1 second at maximum bit rate) |
| Interlaced Encoding | Yes |
Main Profile, High Level
| Parameter | Value |
|---|---|
| Template string | "MP@HL" |
| Appropriate devices | Computers using DirectX Video AccelerationHigh-Definition Windows Media enabled DVD players Digital cinema high-definition streaming |
| Maximum resolution | 1920 x 1080 |
| Maximum frame rate | 30 fps @ 1920 x 108060 fps @ 1280 x 720 |
| Maximum bit rate | 20 Mbps |
| Maximum buffer size (in 16384-bit units) | 2442 (about 2.66 seconds at maximum bit rate) |
| Interlaced Encoding | Yes |
Generic Main Profile
A stream that complies with the algorithmic limitations of the main profile, but does not fit into one of the level specifications, will be assigned "MP" as its device conformance template string.
Complex Profile
| Parameter | Value |
|---|---|
| Template string | "CP" |
| Remarks | The complex profile has no explicit limitations. It is used to enable all of the codec algorithms, usually for demonstration purposes. |
The following tables list the parameters of the device conformance templates for the Windows Media Video 9 Image codec.
Video Image Level 1
