BD file compression with Handbrake

[AcuDefTechGuy]

Okay, so after I rip the BD discs into MVK files (makeMKV), I use Handbrake to compress the files. For example, going from a 30GB MKV file to a 6GB MKV file in about 2 hrs (depends on movie). A RF value of 20 may produce a 9GB file, while a RF value of 22 may produce 6GB, and a RF of 23 may produce 4GB, etc. The resulting file sizes are not linear, but those are just examples.

Handbrake allows for 2 types of output files - MP4 and MKV. Only the MKV allows for DTS-HD Passthrough.

So the DTS-HD MA movies work great on XBMC.

But there is NOT a Dolby TrueHD Passthrough!

So if I want to compress a TrueHD file, I have to use the Dolby AC3 Passthrough or similar.

Anyone know how to get TrueHD Passthrough ?

I'd aim for compressing the video separately, then muxing audio in after using mkvmerge. Select the video stream from your x264 encoded video file and the audio stream from the original uncompressed rip, and behold. (I've never done it, but I'd imagine that's how it should work.)

I use RF value of 22. I usually put 3 audio tracks. DTS-HD, DTS, and 5.1 FLAC from the DTS-HD track. A 30GB file comes out as 10-12GB.
Not sure about TrueHD. I have 50 bluray discs and none of them have a TrueHD track.

Yeah, I also use RF 22 as it seems to be a good balance.

It's a good thing most movies are DTS-HD MA. Some are unfortunately still TrueHD.

Good idea about putting multiple sound options. All my AVRs are DTS-HD capable, but I wonder what would happen if I play it back on an older AVR w/o HD audio.

Although I thought DTS-HD always contains the DTS-core just in case. Could be wrong.

This is what I've always done. Works very well.

There are a few tools that allow you to automate this process. Clown BD is one that I used to use, but it has been quite a while. If you are familiar with mkvmerger I would just use that.

That's just one too many steps for me.

It's just kind of funny how Handbrake can implement DTS-HD MS pass-through, but not Dolby TrueHD pass-through.

No big loss because most movies are in DTS-HD.

I've always preferred DTS over Dolby anyway. This is just yet another reason to like DTS over Dolby.

Question: Why not just keep the full quality BD? Storage space is cheap now.

You ought to give it a try anyway. The makemkv step is already the heavy leg work. The mkvmerge step only takes another 2 or 3 minutes since you're not performing another transcode.

It's just fun and cool to see a 30GB DTS-HD MA movie shrunk down to 6GB and still sounds as great and looks almost as great.

Storage is not an issue for sure.

I'm struggling with handbrake audio, WIN7, media player, receiver interface. By the time it gets to the receiver, its only seeing 2ch sound. Ripping regular DVD's with DvdFab no problem.
