VP6

True Motion VP6 is a video compression codec created by On2 Technologies and licensed for Macromedia Flash, known as Flash 8 Video. Uses a modified non-standard fixed-point integer DCT, with complexity adjusted as a function of target quantization. Significant quality improvement for Flash video (replacing Sorenson Spark as primary Flash video codec) but not as good as H.264 (see Transitions, Inc., white paper on Flash Video Codec Comparisons at http://workflowed.blogspot.com/2009/02/on2-vp6-h264-comparison.html)
