ASFCut is a command line utility for cutting out fragments, joining, modifying and repairing ASF files. ASFCut can be applied for any ASF file, that is, not only those with ASF extension but also those with WMV and WMA extensions. The whole operation is performed without any performed recompression. Thus the video quality is not degraded. ASFCut can simultaneously perform all mentioned actions including audio stream(s) shift with only one single pass. The result of an operation is always one media file. Maybe the most important feature to many of you is the fact that ASFCut can handle damaged files. It simply skips bad area and starts after finding next good frame. Of course if an ASF file has damaged header then repairing will not be possible by this software.
