ASF Editor is a Direct Stream editor for ASF and WMV and WMA files. It uses the command-line version of Asfbin for processing so it can be considered as a frontend for Asfbin.

It uses two parts for editing: the player and the recorder. You open files in the player then you mark parts of the media (preferably on key frames) and record the parts with the help of the recorder.

The recorder can join parts from other files that you open in the player during the editing process. In the end, you can save your files on the recorder part.

You can get a fullscreen preview by double clicking the video windows. Mouse wheel and right mouse button can be used to rewind/forward and play/stop.
