There are bit depths listed but it's not clear to me. One the left it says profile0 (8 bit and 10 bit 4:2:0) 4k60 video, 16K still. The text on the right side is confusing. Intel only supports 8 bit for AVC by the way. |

This is an RKL-S slide, you can never know if there is a newer decoder build in for RKL-S because it comes about half a year later than TGL-U. Also this slide isn't as detailed as today's leak, it could be a mistake there. 12 bit HEVC but not for AV1, it could be. |

Dolby Vision is internally 12-bit, and does tricks with dual layers or a non-backwards compatible base layer and metadata to reconstruct the video in an internal 12-bit format. If we had 12-bit decoders when DoVi was coming out, we'd probably just have a HDR-12 base layer + metadata.
Only current use of 12-bit for anything I can think of is in intermediate post production or high end mezzanine formats like J2K IMF. |

Even in this leak there is a discrepancy. In the table there is 10 bit for video but the text says it's 8 bit for video. I'm keen to believe the table in this case but not sure. In the RKL-S slide there is 12 bit AV1, it could be just a mistake (confused with 12 Bit HEVC), it could refer to still image or it could be that the Gen12LP in RKL-S uses a newer decoding unit than TGL-U. |

I think you're misreading a table converted to text. The table says "profile 0 (8-bit and 10-bit 4:2:0) 4k60 video, 16k still (HW decode)". The text says "AV1 codec support<newline>Profile 0 (10-bit 4:2:0)<tab>16k (still picture)<newline>Profile 0 (8-bit 4:2:0)<tab>4k x 2k (video)". I inserted the <tab> because it matches what the table says: 4k60 (4k x 2k) video, 16k still (picture) and each supporting profile 0 (8-bit & 10-bit, 4:2:0).

Dithering should be fine. Does --help include a description for --denoise-noise-level? It might be built without CONFIG_DENOISE (in which case the --help output will be missing also). Otherwise I'm not entirely sure, it has worked fine for me. Does it work on 8-bit material?

Oh man, the new Cortex X1 CPU core has twice the NEON units of the A78 and previous Axx cores.
At 4x 128 bit units that's some real grunt for an off the shelf design, should be noice for encoding. |

What kind of beast of a computer would you need to play 8k AV1?
I wanted to check out a few 8k videos on Youtube, but I accidentally downloaded AV1 streams, and the videos ate up my R5 1600. Even VP9 did... I wonder if any mere mortal will have such a machine in the next decade. Last edited by mzso; 28th June 2020 at 16:30. |

Beast machine? You used the wrong player!
In my browser it is almost smooth, with some dopped frames In mpv it is perfect with ~ 55% cpu My pc: ryzen 2600 (no oc) + gtx 1070 8K Video: https://www.youtube.com/watch?v=ChOhcHD8fBA

gtx 1070 does not have a HW AV1 decoder...
And mpv uses the dav1d decoder which works on cpu only.
