It is the engineers of Facebook who have experienced and who have made the observation: the new codec AV1 is particularly powerful when it comes to making compression gains in high definition and standard definition.
---New AV1 codec particularly promising---
As a reminder, the codec is an unprecedented compression technology. And Facebook engineers have just tested the device on the network. It turns out that the results look very promising following this experiment. And not common element, the test was not performed as in a laboratory, but "close to the most common real use cases". It is for these researchers to have convincing results with this protocol, as they have also indicated on the Facebook blog: "By proceeding in this way, we can see how the codec will react in a real environment of production ". And the results are positive, well beyond the forecasts made. These tests, made in high definition and standard definition, promise a bright future for open source code. Thus, it shows much better results than the VP9, as shown by the experiments carried out.
---Performance results that go beyond expectations---
These independent tests, carried out by Bitmovin, show that the VP9 only brings a performance gain of 13 to 27% for the compression ratio, much less than what the AV1 codec can offer in terms of performance. . Thus, the tests conducted by Facebook engineers "show that AV1 exceeds the stated target of 30% on the compression ratio improvement compared to its predecessor VP9 and reached respective gains of 50.3%, 43.2 % and 34% compared to x264 in standard definition, x264 in high definition and libvpx-vp9 ". And it is not only for the standard definition and high definition domains that the AV1 codec promises to be promising, as the experimentation also leads to the conclusion that this open source codec "will be even more effective on the contents UHD / 4K and 8K ". In the end, the test conducted was particularly conclusive.
