Blu ray to Mkv lossless

[Oktober]

I'm searching for a procedure/tool which can help me about:
- Convert Blu ray to Mkv without quality loss (possibly using freeware tools)

I didn't find some solution. All i found, uses reconverting with quality loss.

My original problem is that BD_Rebuilder can't fit automatically a BD to BD-9 when use "alternate output to Mkv".
So i want use BD_rebuilder in "Normal Mode (Shrink to BD Format), flagging "Fit to BD-9" and then, convert without quality loss, in mkv.

Thanks

When you specify "Fit to BD-9" you are asking for a recode at a lower bit rate to reduce file size to fit DVD-9 media.

All of that reduces quality.

If you want to maintain BD quality use BD media or cut the program into 7.95GB chunks.

Question: My garage is only big enough to fit a Honda Civic. How can I fit my Humvee into it?

Answer 1: Crush the Humvee to fit. There may be some loss of quality:


Answer 2: Disassemble the Humvee and store it in three garages. No loss of quality but a bit of a pain getting to work each morning.

@jagabo: ah,ah,ah,...ah,.......ehm...Boh

@edDV:i'll try in other words: for me, BD_Rebuilder do the best job to shrink a BD into 8 GB size. The problem is: BD_Rebuilder enable flag of "automatically shrink to 8 GB", only when you choose "BD Structure". If you want a mkv, that setup is grayed out, so you must try several times (with 60-70 hours compressing eachone), adjusting the CRF field to find the correct output size. I thought it was more simple this process:
- Shrink orig BD with BD_Rebuilder using auto sizing to BD-9 (8 GB), with BD Structure as result
- Transcode (only, without recompression), this to mkv. Only in this case i don't want another recompression

use makemkv or for manual, use clown_bd to demux audio and video, then mkvmerge to remux. note you cannot make one mkv of whole blurau/dvd with menus

60 - 70 hours ? Your settings are way too high if your encodes are taking that long. Easier to find the correct bitrate and do a two pass encode instead. The author of avchdcoder also has a standalone version of that programs bitrate calculator. It can tell you what bitrate you need to fit a particular size.

Many thanks to ron spencer & guns1inger.
I already use Clown_BD (Very good Sw), but i don't know mkvmerge. I'll study it.
Thanks also for AVCHDCoder, with his bit calculator. I'll try soon.

60-70 hours: yes. I have a poor Pentium 4 3,6 Ghz Single Core, and setting BD Rebuilder to Highest Quality, it takes 70 Hours to shrink AVATAR (2 hours 40 min lenght).

P.S. Sorry for my english. I'm italian.

Here are several guides I have put together on creating mkvs from Blu Rays:

I would recommend either MakeMKV, Another EAC3To GUI, or Clown_BD + MKVMerge

Grandissimo dbone1! (translation: you are the greatest!!!)

You answered me with your guide "Another EAC3To GUI" [..] to create an mkv from either a Blu Ray or HD DVD disc. No encoding is done so you are left with a perfect 1:1 copy of the original disc. .

Thank you, very very much!!!


Well,
Because all of you are expert, i have another question. Do you know some solution to understand which is the correct angle to rip when i have multiangle Disc? The unique solution i know, is to play the movie and check if there are some words in my prefered language (italian of course)

lossless? any type of encoding there is quality loss. why not just rip to computer.

In my post #4 i explain why i'm looking for that.

[guns1inger]

Do you want a 1:1 copy of the original, or a version that fits into 8.5 GB ? You can't have it both ways unless you make one version of each

Problem: I have a 44 GB BD Original (ripped). I want shrink to 8.5 GB mkv.

Solution i found: Shrink BD with BD Rebuilder to a BD Structure result. Size BD-9 (8.5 GB). To transcode this BD Structure in a Mkv container (without another compression) i found (thanks to dbone1) AEAC, which transcode a BD structure to Mkv container.

Just how are you expecting to shrink 44GB to 8.5 GB without further compression?

Skip 4 out of 5 GOPs? Cut movie to 20% best scenes?

[jagabo]

I think what he's saying is that he is using BD Rebuilder to shrink the video from 44GB to 8.5 GB and he knows he is losing quality doing this. But it leaves him with a BD structure, not an MKV file. He then want's to convert that to an MKV file with no "further" quality loss. Which he learned he can do with a simple remux in MKV Merge.
