Using profiles

A profile is a collection of command-line options tailored to the type of content being encoded, the connection speed of the intended audience, and the desired image quality of the output. The options stored in a profile include the audio and video bit rate, frame rate, video size, client connection speed, and codecs. Windows Media Encoding Script includes a number of profiles that you can use to simplify the process of setting up an encoding session. Instead of specifying each individual setting that you want to use to encode your content, you specify a profile name, and then all settings within that profile are applied to the content.

If none of the system profiles meet your needs, you can create your own profile by specifying each of the options you want to use in the command. You can append the -saveprofile option to the end of the command to save your profile and use it again. Profiles have a .prx file name extension.

The profiles that are provided with Windows Media Encoding Script are not editable. However, you can override profile settings by appending other command-line options to the command. For example, if you use the av700 profile, which has an image quality setting of 75, and you want to change the image quality setting to 100, you can use the –v_quality option to specify the change. For example:

cscript.exe wmcmd.vbs –input C:\My-clips\Myfile.avi –output C:\My-clips-coded\Myfile.wmv –profile av700 –v_quality 100
