  1. Hi guys, I am just trying to confirm something. Latest version of DVDFab 9.0.7.0 have something very interesting. Now you can create an MKV from let's say untouched BD50 by not using H.264 like before but by selecting copy video box or passthrough profile. In the past I wanted to create an MKV file with maximum quality of video and sound in 7.1MA. Now with sound everything is the same you select same as source and here you got 7.1MA, but with video I found that by selecting same as source (copy video) you get much better quality of video than if you select custom H.264 and will put 30000 kbps in bit rate box. I just tried to get gladiator bluray ISO and I end up with smaller file and much better picture quality, and also no encoding needed I managed to get an MKV within 10 minutes. I guess my question is, I am right you do get "source" quality video and smaller file by NOT encoding it with H.264 ? This MKV is only 26.4 GB when original ISO is over 40GB. I did removed 3 other non HD sound tracks with other languages.

    P.S.

    I had one concern about all this not making H.264 codec, my Samsung TV. I have PC Media server with XBMC and HDMI out so I can get nice HD sound out and have best picture quality, that I use all the time. But sometimes I like to connect hard drive via USB straight to my tv and TV connected to AVR using HDMI with ARC included in stream. So I was thinking this kind of mkv will not be played on TV because TV can't decode native AVC codec. Well I was wrong, TV perfectly play this MKV without problem. So here it is, Full movie in about 10 minutes with better quality and it plays on TV if needed. Perfect.

    IF anyone have any questions or may be can add (may be I am missing something) let me know.

    If it only takes 10 minutes I doubt it reconverts.

    You could also try MakeMKV and just select the main movie and see how it big it gets. It doesn't reconvert.

    Correct, I mean that what's Passthrough profile means, I guess my question was it's always better not to touch original to get maximum quality, right ?

    If you convert back to bluray format (with a BDMV and Certificate folder) using a program for example BDTOAVCHD would the quality still be as good as the original?

    If it truly is passthrough, all it is doing is ripping (and decrypting, if necessary), demuxing from the M2TS container to elementary streams, and remuxing into the MKV container. No quality loss.
    A subsequent re-authoring of those same assets to BD, or to AVCHD (bitrate limits permitting), would yield a title of identical quality to the original BD, assuming the authoring software didn't try to do some re-encoding behind the scenes.

    Only exception I see to this would be 3DBD, where all current softwares must decode after ripping (when converting), thus requiring a re-encode of some kind.

    That was actually my follow up question if possible.


    In my understanding (correct me if it's wrong) original Blu-Ray disk or ISO image on playback produce 2 images (left and right eye) and both images are 1080p (aka full frame, also very important correct me if wrong). So there is no way at the moment to create full frame 3D rip, therefore it's impossible to make 3D MKV with Blu-Ray quality. And for all people with libraries need to have original ISO to playback in full frame 3D.


    IS this all correct or I am missing something, in nutshell I want to know how to make 3D MKV in bluray quality or impossible yet.


    Thank you !
