Can possess the following values:

Value	Description
1	Uncompressed Video
827739479	Windows Media Video V7
844516695	Windows Media Video V8
861293911	Windows Media Video 9
827544397	Windows Media Screen V7
844321613	Windows Media Video 9 Screen
826496599	Windows Media Video 9 Advanced Profile

VideoBuffer

VideoBuffer - maximal delay between receiving and displaying the stream. The measurement unit is ms.

Width

Width - frame width in pixels.

Height

Height - frame height in pixels.

FrameRate

FrameRate - number of frames per second.
Default value - 25.
The following values are usually used: 23.976, 24, 25, 29.97 or 30.

VideoSAsInput

VideoSAsInput - parameter responsible for using input file characteristics when converting.
Default value - false.

Can possess the following values:

Value	Description
false	Don't use input file characteristics
true	Use input file characteristics (Width, Height, FrameRate)

ResizeMethod

ResizeMethod - video frame resize method.
Default value - 1.

Can possess the following values:

Value	Description
0	Stretch. The image will be stretched to meet the new values of width and height
1	Letterbox. Black bars will be added to the image so that it meets the new values of width and height
2	Crop. The image will be cropped to meet the new values of width and height

ResizeQuality

ResizeQuality - resize quality parameter.
Default value - 1.

Can possess the following values:

Value	Description
0	Normal (Fast). Nearest-neighbor interpolation.
1	Best (Slow). Bilinear interpolation.

VideoQuality

VideoQuality - parameter responsible for the output video quality. The higher the value is, the better the output video quality is, but the lower the conversion speed is.
Can possess values from 1 to 100.

VideoBitrate

VideoBitrate - video bitrate. The special value -1 is used to set automatic bitrate control. The other values set bitrate in bit/s.

AudioCodec

AudioCodec - audio codec.
Can possess the following values:

Value	Description
-1	No sound
10	Windows Media Audio Voice 9
353	Windows Media Audio 9.2
354	Windows Media Audio 10 Professional

AudioBuffer

AudioBuffer - Maximal delay between receiving and displaying the stream. The measurement unit is ms.
The special value -1 - don't use AudioBuffer.

AudioBitrate

AudioBitrate - audio bitrate. The measurement unit is bit/s.

Frequency

Frequency - audio sample rate.
Default value - 8000 kHz.

Can possess the following values: 8000, 11025, 12000, 16000, 22050, 24000, 32000, 44100, 48000 kHz.

Channels

Channels - number of channels.

Can possess the following values:

Value	Description
1	Mono
2	Stereo

WMV

Parameter

Description

VBR

Using variable video bitrate

Value	Description
0	Don't use variable bitrate
1	Use the VBRQuality parameter to set video quality
2	Limit bitrate value (see VBRMaxBitrate and VBRMaxBuff parameters)
3	Use the VideoBitrate parameter as average bitrate

VBRMaxBitrate

Maximal video bitrate value. The measurement unit is kbit/s.

Is used only if VBR=2.

VBRMaxBuff

Maximal value of the VideoBuffer parameter. The measurement unit is ms.

Is used only if VBR=2.

VBRQuality

Affects video quality. The higher the value is, the better the output video quality is, but the lower the conversion speed is.

Is used only if VBR=1. Can possess values from 1 to 100.

VidBuffer

This parameter is no longer used. It's recommended to use the VideoBuffer parameter instead.

WMA

Parameter

Description

IsAV

It's recommended to always set IsAV=1 if a file has at least one video track.

VBR

Using variable audio bitrate

Value	Description
0	Use constant bitrate (not supported by Windows Media Audio Voice 9.2 Lossless codec)
1	Use variable bitrate (supported by Windows Media Audio Voice 9.2 and Windows Media Audio Voice 9.2 Lossless codecs only)

VBRQuality

Affects audio quality. The higher the value is, the better the quality is, but the lower the conversion speed is.

Is used only if VBR=1. Can possess values from 1 to 100.

Parameter Combinations

When converting to WMV and WMA formats, you should remember that not every parameter combination will be correct.
Supported combinations can vary depending on selected audio codec.
