It is much expected from the relatively novel, open, royalty-free AV1
(Alliance for Open Media (AOMedia) Video 1) standard. At this moment, there
are many new variants of AV1 format. It is designed for efficient video
internet delivery and high-quality video transmission. AV1 is recognized as
Google?s VP9 format successor. One of the reference tools used so far for
testing AV1 is libaom- AV1. Nevertheless, due to its time-consuming
performance, there are now different available standalone solutions for
experimental analysis. Here, one such solution AOMedia?s standalone aomenc
(aomenc-AV1) is tested in order to analyze quality assessment based on
constant quality constraint factor. Three different metrics are calculated
for various 4k video content of the same frame rate. Moreover, rav1e
implementation was tested for the same visual data, where rav1e-AV1 also
represents an AV1 video encoder, which is considered reliable and suitable
in most cases, where libaom is not applicable. In this paper, the comparison
results between aomenc-AV1 and rav1e-AV1 are shown.
