What would be the balance of quality vs size for anime?

[zanzar]

lets say there are bd rips that i make , i want to make them as small as possible while retaining the best quality, without minimal detail lose and without blurriness from low bit rate.

lets say i make them 720p when i rip them (in anime there is mostly no detail lose when going from the bd to hd) , and use HEVC format , constant bitrate.
here is a big file i made for the sake of "preserving the detail" and testing.

Format                                   : HEVC
Format/Info                              : High Efficiency Video Coding
Format profile                           : Main@L3.1@Main
Codec ID                                 : V_MPEGH/ISO/HEVC
Duration                                 : 29mn 14s
Bit rate                                 : 3 980 Kbps
Width                                    : 1 280 pixels
Height                                   : 720 pixels
Display aspect ratio                     : 16:9
Frame rate mode                          : Constant
Frame rate                               : 23.976 (24000/1001) fps
Color space                              : YUV
Chroma subsampling                       : 4:2:0
Bit depth                                : 8 bits
Bits/(Pixel*Frame)                       : 0.180
Stream size                              : 832 MiB (95%)

could the 20-30 min ep be made into 100-150 mb HEVC file and look almost identical?

since its anime , lose of detail is a bit different from movies.

Impossible to answer in generic terms.

It depends on the type of anime , how compressible it is . And your tolerance for quality loss -what might be "acceptable" loss for you, might not be for someone else

It's not very helpful, but you have to do some tests and see if it's good enough for you

understandable , just ran a small sample trough handbrake (god this program is terrible) , came out almost the same at 800kbps , beside the problems the program itself (or me from not knowing how to use it) like jagged lines.

But "jagged lines" could easily be user error, or wrong settings in handbrake . eg. it could be not handling source properly eg. deinterlacing instead of IVTCing, might be resizing interlaced material incorrectly etc...

If you don't like handbrake, try something else, maybe staxrip, megui, hybrid, etc... many GUI's to choose from

yeah i know i dont really use it , i just grabbed it for a quick test, also any rec' of encoding program to use with vapoursynth?

I think staxrip, hybrid support vapoursynth. I don't use the GUI's , I just use commandline tools directly

Consider using 10bit ,especially for anime . Helps with banding , better compression ratio in the low to medium bitrate ranges. (Worse at very low bitrates, however) . But if you're aiming to "preserving the detail", that suggests to me using decent bitrates

Do not use constant bitrate, ever. Its compression efficiency is vastly inferior to 2-pass VBR or CRF, so there is absolutely no reason to use it if you don’t have to. I suggest using CRF mode with a value of ~17 with x265 if you want your encode to be near indistuinguishable from your source. CRF mode will adapt to the type of content and will adjust the bitrate such that a constat level of quality is maintained. This will also result in wildly different bitrates, as different types of anime content require wildy different bitrate (e.g. high-motion scenes with a lot of high-frequency detail such as fine grain will consume multiples of the bitrate a regular talking scene or panning shots need). If your priority is file size, you should use as slow a preset as you can since that will generally improve compression efficiency.
