How does H.264 compare with Pixlet?
H.264 and Pixlet are designed for different uses. Pixlet is focused on workflow, designed for digital filmmakers, animators and effects artists to easily review high-resolution image sequences on a standard PowerMac or PowerBook. Pixlet plays every frame of a sequence without frame-to-frame dependencies so that a media professional can scrutinize every detail of a sequence. Pixlet enables high-end digital film frames at 960×540 (at about 20 Mbps) to play in real time with a 1GHz G4 or faster Macintosh, while 1920×1080 frames (at about 40 Mbps) will play in real time on a dual 2GHz G5 or faster. This capability eliminates the need to invest in costly, proprietary hardware for the professional review process. H.264 is a delivery codec, optimized for high quality and efficiency. It leverages data that does not change between frames for more efficient compression. While Pixlet may require about 40 Mbps for 1920×1080 content, H.264 delivers 1920×1080 content at about 8 Mbps.
