Hello!
Where I can found 3rd party filters for Avidemux? For example Unsharp Mask...
With a loaded video and selected video codec in Video Output in Filters. Unsharp Mask is not one of them.
between versions some may be omitted: video filters (http://www.avidemux.org/admWiki/doku.php?id=using:video_filters)
If on windows you could use AvsProxy (http://www.avidemux.org/admWiki/doku.php?id=using:avsproxy)
If you have program experience: you could write your own filter (http://www.avidemux.org/admWiki/doku.php?id=tutorial:writing_your_own_filter)
Can someone add Unsharp filter to Avidemux?
