Hi!
As I mentioned in the Intermediate Video Format survey thread, I've been developing a new fast lossless video codec (named MagicYUV) for Windows, it's been basically ready since a year ago, I just never got the time to release it.
But now it's here, I've fixed some remaining bugs I've known and I guess it's ready for an alpha release.
I've set up a website, you can grab it from there:
http://magicyuv.com
I've also uploaded a command line tool
avibench there, that can measure codec compression/decompression performance through AVI files.
Any kind of suggestions, comments, bug and crash reports, feature requests can come here. The target is to make it to 1.0 stable
Greets,
I.
