Using profiles
A 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. If you do not specify a profile for a session, the following default options are used for the profile:
- Windows Media Audio 9 and Windows Media Video 9
- One-pass encoding
- of 30 fps
- Height and width that match the input source
- Stereo channel audio
- of 44,100 hertz (Hz)
- Buffer of 5,000 milliseconds
- Smoothness setting of 75
- distance of 10 seconds
- Audio and video bit rates of 64 and 250 kilobits per second (Kbps), respectively
You can override any of the default options by appending other command-line options to the command.
You can also create a custom profile by specifying each of the options you want to use in the command. You can then append the -saveprofile option to the command to save your profile and use it again. You can then use the -loadprofile option to reuse the profile or to encode content using a Windows Media Encoder profile. Profiles have a .prx file name extension.
Windows Media Encoding Script includes a number of predefined profiles that you can use in a session (using the -profile option).
