I have encoded all the episodes and specials at 10mbps HEVC.
Audio, subs and chapters have been passed through untouched
This has dropped the size by at least a 3rd. The idea is not to make it as small as possible. The Idea is to reduce the file size with the HEVC codec but maintain the origianl quality. That's why I kept the Audio as FLAC and didn't use OPUS.
All thanks go to SoM, without them, none of this would be possible.
Hope You Enjoy

the colors and resolution are wrong on your release
source: 704x352 (anamorphic)
Color primaries: BT.601 NTSC
Transfer characteristics: BT.601
Matrix coefficients: BT.601
you: 704x540 (non-anamorphic)
Color primaries: BT.709
Transfer characteristics: BT.709
Matrix coefficients: BT.709
i did a test encode with 2000kbps bitrate and used qaac/deew for the audio and the total size was 552MB per episode. with quick math, the total size would be 84GB. i'm sure even 1000kbps or 1500kbps would be good enough.
here are some comparisons between SoM, you, and my test encode; https://slow.pics/c/nwQ1rLyv
The bt 709 was intentional. Works better for HD displays. Colors are the same.
as Stated above, I'm not trying to make it as small as possible. Just trying to maintain the current quality with the HEVC codec. I'm not aiming for good enough, Idea is to maintain current quality.
HEVC tends to smooth fine textures and film grain more aggressively than AVC, especially in anime and grainy content.
If you apply a Rec. 709 matrix to footage originally recorded in Rec. 601 without performing a true color conversion (i.e., if you only change the container's label or flag), you'll cause a display error known as color shifting.
When performing metric comparisons between HEVC, AVC, and AV1 using ffmpeg-quality-metrics, the results favor AVC in first place, followed by AV1.
That said, it's your project, so enjoy it.
Thanks for that, I did put it through the correct math calculations process. There may be a slight shift in saturation or luminous. But the colors haven't shifted to different colors, like from red to orange. That being said. Playing bt 601 on a HD display will display slightly different from the original source.
We can pull out all the specs and do all the side by side comparisons. But actually watch it on your TV and decide from there.
