In this presentation, google's image and video compression codec were compared to major image and video compression standards including JPEG, JPEG XR, JPEG2000, x264, and HEVC (H.265). It is concluded that

1. VP8 image compression showed performance comparable to JPEG XR and JPEG2000, all significantly outperforming JPEG
2. VP8 video compression showed performance competitive with x264, while the new HEVC showed the best performance
3. For some contents, both VP8 image and video compression did not do good job for low bit rates control.
