What is VP9?

VP9 is Google's next-generation open-source video codec delivering 50% better compression than VP8 for 4K streaming.

What is H265?

H265 (video/h265) uses lossy compression optimized for ultra hd video encoding, 4k/8k content. Raw H.265/HEVC stream, high-efficiency video coding

When Should You Use VP9 vs H265?

Use VP9 When...

Reach for VP9 when your priority is youtube 4k, web video, chrome streaming — its efficient compression makes sharing fast and storage minimal.
