rav1e 2021.03.02 pre-release

rav1e is designed to eventually cover all use cases, though in its current form it is most suitable for cases where libaom (the reference encoder) is too slow.

Features of rav1e:

- Intra, inter, and switch frames
- 64x64 superblocks
- 4x4 to 64x64 RDO-selected square and 2:1/1:2 rectangular blocks
- DC, H, V, Paeth, smooth, and all directional prediction modes
- DCT, (FLIP-)ADST and identity transforms (up to 64x64, 16x16 and 32x32 respectively)
- 8-, 10- and 12-bit depth color
- 4:2:0 (full support), 4:2:2 and 4:4:4 (limited) chroma sampling
- 11 speed settings (0-10)
- Near real-time encoding at high speed levels
- Constant quantizer and target bitrate (single- and multi-pass) encoding modes
- Still picture mode

As GUI (Graphical User Interface), we suggest to use rav1e GUI - it allows you to encode your video files to the AV1 video format easily and fast. See more info on developer's page.
