movtoy4m
Brightness patch
Tyler has submitted a patch for movtoy4m that makes the image appear a little bit brighter, closer to the source image. I don't have time to test it myself, so I'm just going to post the updated source code here. If you use it, you should first do some testing to make sure it works ok. The source code can be downloaded from the movtoy4m page.

Oh, and here's a link to Tyler's program: http://www.isquint.org/
Intel movtoy4m!
Tyler Loch has sent me a patch that makes movto4ym run natively on the Intel architecture! Turns out that only two lines needed changes, and not ten times that, as I had feared. For the curious, k32ARGBPixelFormat was changed to k32BGRAPixelFormat. Thanks QuickTime, and thanks Tyler! Download the latest version of movtoy4m on this web site.
Intel movtoy4m?
A number of people have asked me if there is or will be a version of movtoy4m available for the new Intel platform. The short answer is: No. The slightly longer answer is: No, but if you want to make such a version, you're most welcome. The reason I will not be releasing a new version of movtoy4m is that it is not just a simple recompile, and doing any major work on it would clash with my current obligations with another project. If some kind soul decides to update the tool I will post the updated binary and source code here.

The problem with just recompiling movtoy4m is that it was written at a time when running Mac OS X on an Intel machine seemed very unlikely, and therefore it has some byte sex issues. Anyway, you can download the source code and give it a try. Don't forget to send me any patches to the code so that more people can benefit from it.
