I've tried some filters, but i get a black screen and no audio.

Also, with Avidemux the output file has poor quality and sound is out of sync.

Input Plugins

MPEG2 (by fcchandler)
WMV (by fcchandler)
AC3 (by fcchandler)
Flash Video, including H264 and AAC (by fcchandler)
QuickTime (by tateu)
Flash Video, no H264 or AAC (by Moitah)
DirectShow (by phaeron)

When using plug-ins it is recommended to use the latest version of VirtualDub, or at least the version that is recommended in its documentation.

You also need either Quicktime or Quicktime Alternative.




Here, a brief explanation is given of how to use the input plugin system to open some file formats that VirtualDub doesn't handle natively.

WMV, M2TS/MTS, MP4 and Matroska (and potentially many other types) via DirectShow

Requirements:
DirectShow input driver (place this in .\VirtualDub\plugins\)
Haali Media Splitter (for MP4, M2TS/MTS and Matroska)
ffdshow-tryouts (for MP4, M2TS/MTS and Matroska)

All you have to do is simply open the file in VirtualDub like you normally would. In case your file doesn't show up, select 'All files (*.*)' from the file type list and after selecting your file, select 'DirectShow input driver' from the file types list.

In VirtualDub, when opening MP4 files, use the "Ask for extended options..." option in the Open File dialog, then try the different options. Also try force Quicktime or MP4 file type. Some combination of those will usually work.
