Brooke Vibber :neocat_cofe: on Nostr: my rough mappings for experimental AV1 transcodes: 2 Mbps for 480p/480i/576p/576i <- ...

my rough mappings for experimental AV1 transcodes:

2 Mbps for 480p/480i/576p/576i <- from ~5 Mbps MPEG-2 on DVDs

12 Mbps for 1080p/1080i <- from ~24 Mbps H.264 on Blu-rays

60 Mbps for 2160p HDR <- from ~75 Mbps HEVC on Blu-rays

(for interlaced sources I have to deinterlace))

However I'm not certain my current AppleTV groks AV1 in hardware, I'm going to have to do some test runs before I commit to anything.

And I'm not committed to re-encoding in the first place still, just fiddling around.
