![]() ![]() High tier for 4.1 and 5.1 is high enough either way to not interfere with encode quality that much. And by doing so your encodes are much less prone to bitrate spikes that can cause playback issues down the line (network playback or some hw-playbackdevice etc). level-idc 41), but by doing so you are enforcing the vbv limits compliant to that level (i.e. Not everyone is into specifying the level (i.e. Going up to 8 bframes could be an good option as well, doesnt have much drawbacks and a few titles might enjoy it. If you are more in to trying to keep video as lossless as possible you might wanna use aq-mode 1 instead of the default mode (2) as well. and thinking back to when I paid $5000 for a 4 GB RAID, and couldn't believe how cheap that was.Ĭode: -colorprim bt2020 -transfer smpte2084 -colormatrix bt2020nc -max-cll "1000,400" -master-display"G(13250,34500)B(7500,3000)R(34000,16000)WP(15635,16450)L(10000000,1)"SDR/HDR/Resolution can effect perceived quality given crf value a bit differently so you will probably have to play with that a bit. ![]() And few titles use close to that much for the actual main title. $/TB has dropped below $20, which means cost to store a full BD-50 image is <$1 now. ![]() ![]() Given how cheap HDs are these days, it's generally cheaper to just buy more storage than to reencode. As 4K Blu-ray is already HEVC, the potential file size reduction without quality loss may be less than you expect. Of course, going to UHD is ~4x slower, or ~5x slower if you're going from 8-bit to 10-bit. I like slower as it is where a lot of the cool HEVC features kick in, but that's more my personal preference that a requirement. X265 -preset medium should outperform x264 -preset slower with roughly similar speed. I would like to store my BD FHD and UHD as a MKV with a reduced size but keep quality. I would keep a good quality, currently I use x264 preset slower CRF 18 but slower is very very slow with x265 (using Ryzen 7 3700X) so perhaps preset slow only. ![]()
