    Hello all,

    I am currently attempting to convert my BluRay hard copy of Grimm (Seasons 1-4) to a digital copy, so that I can play it on other devices like my tablet, that don't have a BluRay disc drive. I physically OWN this media, and have not acquired it by illegal means, nor do I intend to SHARE it (illegally). I am more familiar with H.264 format and have already successfully "ripped" all 4 seasons. However, in H.264 format all 4 seasons take up over 250GB and is beyond the storage capacity of many of my devices. Which is why I wish to convert them into H.265(x265) format.

    I have read through several forums on what the "optimal" settings are for achieving the best video Quality using a x265 Encoder/Transcoder. However, most of the threads I've read appear to discuss either optimal Film settings, Anime settings, or suggest the use of settings that result in 750MB+ file size(s). For example, here's what I get with a slightly modified version of "Littlepox's" "tune film" settings from Doom9's forum:

    My goal is to shave approximately 200MB off the file size to around (550MB), while maintaining a (Video) Bitrate >1500 KB/s and a QP Value ~(22-22.5). I've achieved the above criteria, but, I've got no idea if I did it in the most efficient way possible..

    It seems like I should be able to increase some things and decrease others, to improve the quality. I'm not as experienced with Video Encoding/Transcoding as some of you other guys, so Any advice on what I show raise/lower (or turn off) to help FURTHER improve the Quality would be MUCH appreciated!

  2. Why 4:4:4 ? It's a waste of bandwidth since the source is 4:2:0

    Can your tablet or other devices even play 1080p 10bit HEVC ? Most tablets and many devices can't yet or you'll drain the battery in about 20 min

    Why do you think the source is I420?

    And yes, I have a Microsoft surface pro 3- which does pretty well with H.265. It goes about 45 minutes before I need to plug it in- which is no problem.

    "regular" 1080p blu-ray is 8bit 4:2:0

    There are potential benefits from using 10bit encoding from an 8bit source, but no benefit in upscaling the chroma . You'll just need larger filesizes for similar quality
