On machines with a Matrox board and drivers before version 7.5, there’s always a matching VFW-Codecs pack available with the driver. On machines with a Matrox board and driver version 7.5 and higher, you do not need to install VFW-Codecs since they are included in the driver.

As said, the video file is correct and you should be able to import it into other video editing applications without any problems. The AVI video file contains pure RGB data, but the Media Player dithers it (often using only 16 colors) for some unknown reason. Also, some codecs will crash unless they get a handle.įiles created in raw uncompressed mode can display artifacts when played back in Windows Media Player. As a result the configuration windows of some of the codecs will fail to show. The Viz Artist plugin interface is unable to supply such a handle. Some codecs require a handle to the top level application window. Otherwise the alpha channel will be completely blank, thus making the whole video totally transparent. If you plan to use an RGBA video in a program that can handle alpha, you need to make sure that you have KEYFunctions on containers you want to have visible. Some codecs will work with RGBA but will nevertheless store the video as 24bit. You may need to change between RGB and RGBA to get a specific codec to work. Not all codecs support both 24bit and 32-bit video. Try creating an uncompressed video using RGBA to create a more common 32-bit uncompressed video.
