On2 VP8
- U) D* A: N/ w0 [The latest generation proprietary video compression format from On2,  VP8™ introduces more than 40 new innovations to the well established technologies used in On2 VP6 and VP7. Including golden frames, processor-adaptive realtime encoding and a low-complexity loop filter, On2 VP8 delivers outstanding quality at low bitrates with very low complexity.

Designed with a wide range of machines in mind, from 100 MHz ARM 9 processors to today's highly parallel multicore processors. It encodes in realtime on low end machines, and takes fewer cycles to decode than other leading algorithms.

Lowering the cost of video throughout its lifespan
Through exceptional compression performance, On2 VP8 brings potentially huge savings in bandwidth and storage costs. Its computational efficiency lowers the cost of encoding by enabling greater throughput. And with no patent-pool royalty hassles, VP8 licensing terms are flexible and affordable to ensure maximum ROI potential.
