I was just curious what programs (Handbrake, VidEncoder, etc) and settings MakeMKV users are using to compress MKV files. I'm especially interested in learning what compression settings people are using for 1080p Blu-ray conversions. I'm OK with sacrificing some quality to save 20GB of disk space, but what are some recommendations that would allow me to maintain high video quality and achieve a reasonable file size?

The hands down winner is BD Rebuilder, to use with your ripped (by MakeMKV or other) Blu-ray disc BEFORE using MakeMKV to convert the main movie to an .MKV file...

That requires a re-burn to physical media, but for those of us that use a NAS over a physical disc library this isn't really an answer.

I'd imagine the question relates to achieving a .MKV format but optimally compressed video that doesn't affect quality visibly.

I hear Handbrake quite often on this topic, but perhaps one day MakeMKV will include some popular transcoding and compression options (MP4, 2-pass light weight compression leveraging multiple CPUs for speed etc.)

No - There's nothing in the use of either BD Rebuilder or MakeMKV that REQUIRES burning to physical media. All activity, files and folders can be saved directly to hard drive, without burning to disc...

And again, NO, as those are directly contrary to the stated purpose of MakeMKV - and besides, there are presently enough other programs to address those desires...

I am using handbrake+foobar2000+(sometimes)eac3to+mkvmergegui.

I encode the video with handbrake (1920x1080, high profile x264, constant quality = 19). Depending on the source, CQ=19 can be overkill, but that way I cannot see the difference between the encoded file and the source. But that's me...

When the BD comes with DTS audio, I demux it (with mkvmerge) and encode it to AAC with foobar2000. If it comes with trueHD audio I encode it to flac with eac3to and them to AAC with foobar 2000.

If the audio tracks are in AC3, I mux them directly.

After all that I am with the audio tracks, the video track and subtitles tracks (downloaded SRTs). I mux them with mkvmerge.

Pretty much the same settings at mogazz.

However, I don't bother with muxing, and just let Handbrake handle it all, and I also crop the black bars out. I do change the order of the audio tracks if an HD audio track is present since OS X doesn't play nice with HD audio(or so they say at the Plex forums).

I have been processing all my 1080p MKV files in Handbrake at the High Profile setting 3500Kbps data rate and 2 pass selected. To the casual eye the resulting files are on par with the original media when played on my 1080p sets through the AppleTv (3). I also process the same file as Baseline Profile at SD resolution, 2 pass for playback on the original AppleTv and other legacy devices. As for handling PGS subs without resorting to multiple tools I use the Turbo.264 HD to preprocess my MKV to burn in the PGS sub set of my choosing which I have detailed here: viewtopic.php?f=4&t=4814

That's correct 100%!
but for this reason that I will never buy this program after the 30 days trial.

Too many steps for a person that it's not able to use other program... MakeMKV is very good because it's easy and user friendly, I tried to use other program... like HandBrake but it's not quite easy to use as MakeMKV... and will never store into my 6TB NAS a 30GB movie... so I prefer to move in other way to have my personal BD stored into my NAS with smaller MKV video.

This can be a chose of the creator... but it's also a my choise to buy or not to buy... and for this reason I will never spent 50 euros for a program that can be good only for the 15% of my movie (the other 85% of my movie are too big).

That's all... and for me there are no problem.

As a relatively newcomer to the decode-encode realm, can you please give me some idea of why you do these extra steps as opposed to allowing Handbrake (one step program)?

What is the benefit of the various programs separately created output?

I don't really know the benefits of trueHD/DTS but I know that currently handbrake doesn't handle those file types.. atleast to my understanding. That means you have to mainly extract those tracks from the original source and remux the file with those tracks (After handbrake has encoded).

I use a autohotkey script to monitor my dvd drive and then rip using makemkv and compress using handbrake. Here are the current CLI settings I use for handbrake:

Code:
-F --subtitle scan -N eng -e x264 -q 23 -a 1,1 -E faac,copy:ac3 -B 160,0 -6 auto,auto -f mkv -m

My family generally doesn't appreciate differences in quality, thus I favor an approach that is "very good" in both audio and video quality, but saves on disk space. If I want the full HD audio and unmolested video experience, I'll view the source disc instead. I use Handbrake for everything (generally nightlies) unless it's 1080i VC-1 source, which requires something else like RipBot264 instead.

My settings for each type of source (good balance between encode performance and reasonable quality):
  • Common to all: MKV using H.264, keep original source size, but with loose anamorphic, and auto-cropping. Pass-thru AC3, or transcode DTS to 640kbps AC3, no down-mix from 5.1. Keep all English subtitles (especially forced) w/o burning in. for PGS subtitles, post-encode, I use MKVMerge since WDTV doesn't handle Handbrake's PGS approach. Vobsub subtitles pass through just fine. Preserve all chapters. Advanced encoding options at defaults except "b-adapt=2:rc-lookahead=50"
  • 1080p Blu-Ray, CQ at RF22, no filters. Results in a Profile 4.0 file at roughly 2.2GB/hour or about 5-9Mbps
  • 1080i Blu-Ray, CQ at RF22, Detecline and Decomb at "Default". Results in a Profile 4.0 file at roughly 2.2GB/hour or about 5-9Mbps
  • 480i DVD, CQ at RF19, Detecline and Decomb at "Default". Results in a Profile 3.1 file at roughly 800MB/hour or roughly 2Mbps

Avoiding HD Audio codecs entirely, and transcoding 1.5Mbps DTS down to 640kbps AC3 (preserving 5.1 channel) makes for a noticeable reduction in file size w/o any appreciable loss in fidelity.

For Blu-Ray, higher qualities (i.e. RF19 on Blu-Ray) look even sharper and truer to the source, however the encode times are just too long on my aging Phenom IIx4 955 @ 3.2ghz machine for "marginal" improvement, and file size reduction isn't significant enough. RF22 is as good or better than a "cable" HD experience, while encoding at roughly 10fps and yielding "acceptable" file sizes. If your available storage space is significant, then RF19 could work.

For DVD, with fewer pixels overall, anything higher than RF19 is noticeably poorer, and could only be done satisfactorily by adjusting some advanced settings. The encode performance increases substantially if you do, thus it's just easier to go w/ RF19. These net a performance of ~45fps encodes on average on my hardware.

File size estimates are completely dependent upon the type of material - with CG material for kids taking up less space than film-based 1080p content.

In the end, it's up to you to experiment with the results of each settings. For some, one setting may not fit all, but when you're aiming to transcode a library of 100s of discs for the sake of convenience for non-technical family to enjoy, you may opt to compromise on ultimate quality to keep your workflow sane.

After 2 something years, they've either figured it out, or given up in disgust...

(Compression is the least of my problems while ripping discs)
