ASF editor is a directstream editor for ASF and WMV files.It can handle audio files (WMA) too. It uses Asfbin for processing so it can be considered like a frontend for Asfbin. It uses 2 part 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 too you open in the player during the editing process. At 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.
