Many codecs have specific limitations and only work on certain types of input. It is not possible to list all things to be aware of, but here are some:
24-bit uncompressed video is valid, but rare. Some programs may have difficulty in reading such files. Try creating an uncompressed video using RGBA to create a more common 32-bit uncompressed video.
Not all codecs support both 24-bit and 32-bit video. You may need to change between RGB and RGBA to get a specific codec to work.
Some codecs work with RGBA, but nevertheless store the video as 24-bit.
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. Otherwise the alpha channel is completely blank, thus making the whole video totally transparent.
Some codecs require a handle to the top level application window. The Viz Artist plug-in interface is unable to supply such a handle. As a result the configuration, windows of some of the codecs fail to show. Also, some codecs crash unless they get a handle.
Files created in raw uncompressed mode can display artifacts when played back in Windows Media Player. This is some oddity of the Media Player. The AVI video file contains pure RGB data, but the Media Player dithers it (often using only 16 colors) for some unknown reason. As said, the video file is correct and you should be able to import it into other video editing applications without any problems.
