video samples for testing purposes?

I am currently, for a pet project, making a lossless video codec aimed for CGI, cartoons, anime or other areas with have either little colour or large gradients. However I do not have a noise-less (well as much as can be) samples in my codec's domain inwhich to test it with. So does anyone know of losslessly stored sample videos i can download? Once i have an alpha verson working to my satifaction i will probably try to make an open source project to convert it from java to c/c++ and into a vfw or dshow codec.

PNG is well suited to CG images. And there is already a PNG based codec. Perhaps you should check it out before you inadvertantly re-invent the wheel. You should be able to find it over at corecodec.com. I don't know of any lossless CG clips to download. But you could always generate your own. Check for some excelent software that will output lossless AVI.

For any of you that are interested, i have built a prilminary version of the codec. It currently compresses using key frames and deltas, however does not use any motion estimation or any other colour space than RGB. Also, it is HEAVILY un-optimized. It runs very slow :( I plan to finish programming the codec in java being OO and very readable such that i can use it as a reference codec for when I or someone else ports it to C/C++ as a vfw or ds codec. The codec as it is can be found here: A win32 exe installer, java source and a sample sequence are stored there. If anyone has any feedback please to conact me! Sometime this year i hope to have finished programming the codec referecne in java and will be porting it to C/C++. I would like to guage the interest of other people making this an open-source project. Cheers!
