Using VP9 recently has really made me appreciate how great x264 is both in terms of quality and speed.

- pseudosavant 6y agoThe quality of encoders have a much bigger effect on whether or not a codec is 'good' or not. LAME, mozjpeg, and x264 are great examples. MP3 is competitive with AAC and far more compatible, if you use LAME. Same with JPEG and WebP, or x264 and VP9. All 3 of those encoders deliver higher quality AND better encoding speed than their competitors. Switch encoders before you switch formats.
- basilgohar 6y agoYou are comparing an encoder (x264) with a format (VP9). While there is a reference encoder for VP9 (libvpx). x264 has been one of the most heavily optimized encoders whose development was sponsored by many different organizations, whereas libvpx did not see the same kind of love and most of the work came from Google's employees (with some from outside, I'm sure). There exist other VP9 encoders, but all for specialized purposes.

You're getting your facts wrong: x264 was developed by a very small open source community, with at most 5 developers on it, on their free time, while libvpx got quite a few people from Chrome Media Team paid to work for years on it.
