Using Microsoft® Windows Media™ Stream Editor, you can split or combine streams in existing Windows Media files to create files. This tool is useful when you have Windows Media files that were created with multiple bit rates. For example, if you have a Windows Media file containing two bit rates (audio and video streams at 100 kilobits per second (Kbps) and 500 Kbps), you can create a Windows Media file that contains only the 100 Kbps stream.
You can also use the tool to combine streams from multiple input files. For example, if you have a Windows Media file with two audio streams and two video streams, and you want to replace the audio streams, you can create a file that includes the original two video streams combined with audio streams from other Windows Media files.
The following table provides examples of how you might split streams within a file to create additional files.
Input file | Output file 1 | Output file 2 | Output file 3 |
Bit rate 1 | Bit rate 1 | Bit rate 2 | Bit rate 1 |
Audio A | Audio A | Audio B | Audio A |
Video A | Video A | Video B | Video B |
Bit rate 2 | Bit rate 2 | ||
Audio B | Audio B | ||
Video B | Video A |
