AsfBinMaster is a tool that lets you join and cut ASF, WMV and WMA files.

The software doesn't require any installation, so your Windows registry entries remain unchanged. Plus, you can place AsfBinMaster on an external device and easily run it on any computer.

The user interface of the application is standard and intuitive. You can start and save a project, add video files to the queue (the "drag and drop" method is supported), include segments, edit the videos and produce a movie.

In order to cut a file, simply adjust the slider to a specific position, or input the star and end time.

Furthermore, you can preview each clip, toggle display (the clip is either previewed in the software's interface or in a separate media player window) and analyze files to find out information on audio and video bitrate.

In the Preferences menu, you can select "Indexing", "Remove", "Info", "Audio" and "Cut" modes, as well as write attributes.

A task is completed in little time, while AsfBinMaster maintains a fair audio and video quality. However, it is not able to join two or more files of different formats. The only available output format is WMV, though. In other words, the program is a conversion tool in the case of ASF to WMV.

The program uses a small amount of system resources but doesn't come with any kind of documentation. All in all, AsfBinMaster is a very good program for cutting and joining video files, even if it lacks more advanced editing options.
