| I've had a problem with MKV creation using H264 + AC3 since the start of version 5. I have so far assumed that what I'm seeing is a simple bug in DVDFab and even received word from Fengtao that they would look into it back in version 5.0.7.5. I would think this is an easy bug to duplicate and therefor fix but I am no longer so sure. I'd like someone to duplicate the problem to make sure that it isn't something to do with my setup. I've used a custom profile to maximize the H264 quality coming from DVDFab. I'm using a rediculously high bitrate of 10000 to create an H264 reference sample. However, I experiance the following problems:
Code: Format : AVC Format/Info : Advanced Video Codec Format profile : 0@L0.0 Format settings, CABAC : No Format settings, ReFrames : frame0 Codec ID : V_MPEG4/ISO/AVC Width : 16 pixels Height : 32 pixels Display aspect ratio : 0.500 Colorimetry : 4:2:0 Scan type : Progressive Code: Format : AVC Format/Info : Advanced Video Codec Format profile : Main@L4.1 Format settings, CABAC : Yes Format settings, ReFrames : 1 frame Codec ID : H264 Duration : 3mn 50s Bit rate : 8741 Kbps Nominal bit rate : 10000 Kbps Width : 720 pixels Height : 400 pixels Display aspect ratio : 16/9 Frame rate : 23.976 fps Resolution : 24 bits Colorimetry : 4:2:0 Scan type : Progressive Bits/(Pixel*Frame) : 1.266 Stream size : 240 MiB Writing library : x264 core 60 Encoding settings : cabac=1 / ref=1 / deblock=0:0:0 / analyse=0x1:0 / me=dia / subme=7 / brdo=0 / mixed_ref=0 / me_range=4 / chroma_me=1 / trellis=0 / 8x8dct=0 / cqm=0 / deadzone=21,11 / chroma_qp_offset=0 / threads=2 / nr=0 / decimate=1 / mbaff=0 / bframes=0 / keyint=250 / keyint_min=25 / scenecut=0(pre) / rc=abr / bitrate=10000 / ratetol=0.8 / rceq='tex^qComp' / qcomp=0.50 / qpmin=10 / qpmax=31 / qpstep=3 / ip_ratio=1.25 / aq=0 If you should decide to try to duplicate my issue make sure to use one chapter (10000 bitrate remember) from an NTSC DVD with content that was originally a film (a.k.a. a region 1 movie DVD). The board won't let me upload the file again but you can find the profile attached here: http://club.cdfreaks.com/f116/dvdfab...3/#post2101384 Last edited by Complication; 11-10-2008 at 07:47. |

| Is the Bitrate or the framerate 10000?

| So does the lack of responses mean that nobody found the same problem or nobody had time to try this? The latest version, 5.1.0.5 Beta, generates the same result for me. |
Posted: 01-11-2008 - #6
| Dear all, Please try DVDFab 5.1.1.0 to see the result: http://club.cdfreaks.com/f116/dvdfab...-0-out-255492/ Thanks! Best Regards, Fengtao

| Dear Fengtao, The problem persists with the latest release ( the one that has MKV fix in its release log ). My tvix thinks the file is of Zero length when trying to jump in it. VLC will ( latest 0,9,4 ) behave when jumping in the file it will play but the slider will be confused and jump about. This is the exact same problem as earlier so sorry to say its not fixed. |

| I can report that my media players are playing DVDFab produced mkvs now. That's progress. But when trying to remux DVDFab produced mkvs with the subtitle files MKVmergeGUI is quitting with errors each time. The log states the following: Quote:

| This is certainly progress as the output from MediaInfo looks correct: Code: Video Format : AVC Format/Info : Advanced Video Codec Format profile : Main@L4.1 Format settings, CABAC : Yes Format settings, ReFrames : 1 frame Codec ID : V_MPEG4/ISO/AVC Duration : 3mn 50s Bit rate : 8370 Kbps Width : 720 pixels Height : 400 pixels Display aspect ratio : 16/9 Frame rate : 23.976 fps Colorimetry : 4:2:0 Scan type : Progressive Thanks for the effort. |

| As an update, I tried DVDFab 5.1.1.5 Beta and it still exhibits the time code jump problem in VLC and the MKV is not readable in mkv2vob. I'm not sure, but I think something has changed here however. I always test with the first chapter of the exact same DVD title. The time code jump seems a bit different (smaller?). My best guess is that it is a rounding or time conversion issue. I made a working MKV using Handbrake to see the differences in the DVDFab created file. The only thing I can see is that the Handbrake file is reporting more video information on MediaInfo such as: Code: Nominal bit rate : 10 000 Kbps Bits/(Pixel*Frame) : 1.448 Writing library : x264 core 58 svn-736M Encoding settings : cabac=1 / ref=1 / deblock=1:0:0 / analyse=0x1:0x111 / me=hex / subme=4 / brdo=0 / mixed_ref=0 / me_range=16 / chroma_me=1 / trellis=0 / 8x8dct=0 / cqm=0 / deadzone=21,11 / chroma_qp_offset=0 / threads=3 / nr=0 / decimate=1 / mbaff=0 / bframes=0 / keyint=240 / keyint_min=24 / scenecut=40(pre) / rc=abr / bitrate=10000 / ratetol=1.0 / rceq='blurCplx^(1-qComp)' / qcomp=0.60 / qpmin=10 / qpmax=51 / qpstep=4 / ip_ratio=1.40 Again, using tsMuxer to create a MT2S file (and renaming to VOB) from the DVDFab created MKV results in playable file (at least on the PS3). |

| Is there any timeline on when we get multiple audio streams, and subtitles being muxed direclty into mkvs? It's kind of tiring having remux every title using different softare every time. |
Posted: 20-11-2008 - #12
| i am also trying to use mkvmerge to add subs to my mkv (from dvdfab) and am getting the same "malformed codec" error. is this a problem with mkvmerge or with dvdfab? |
Posted: 20-11-2008 - #13
| hi, About current MKV mux problem, I will do some improvement, I hope can fixed them as quickly as possible, but not sure the time.  Quote:
Thanks.

| i re-encoded my video using ripbot264 and there was then no problem getting mkvmerge to mux the subtitles (although the dvdfab-extracted subs didn't work, i had to re-do that, too, with vsrip). just fyi. |

FYI, retried my usual test chapter. VLC's progress bar still jumps back and forth as the movie plays. The MKV file is still not compatible with mkv2vob. |

Posted: 31-12-2008 - #19
| Based on the last post, it seems this is a DVDFab problem. I recently purchased 5.2.2.2 and noticed a lot of little problems as such. I ripped a MKV.H264.AC3 and it plays on both VLC and Media Player Classic. VLC does a horrible job rendering the H264 codec and makes all lettering have jagged edges. Media Player Classic allows for perfect smooth playback of the MKV.H264. Now I know the MKV container file works. I then decided to convert it to a VOB file so I can play it on my PS3. I also tried mkv2vob, but I get the same error, "Could not parse Mkv file" in the tool. This ultimately leads me to believe that DVDFab encodes MKV in a particular way that works for playback, but is not read by other programs allowing you to alter at a later time. I haven't tried muxing the main movie with the subtitles yet, since I am tring to figure out the best way to store the backups with the best video and audio quality, will taking advantage of the great compression H264 has to offer. Try ripping a BR and you will realize that it is a whole lot more challenging and takes 10 times longer to encode the files. I am using Ripbot to rip a disc and convert it right not to MKV, so I will let you know how that works out. M2TS is accepted by PS3, but it is only Stereo, and I want 5.1. This process takes for ever, even on a very powerful computer. |

| With regard to my question, I specifically want to encode h264 mkvs with audio copy. I am running a test now, but wanted to know in advance if it was worth it or not. I'm going to have to remux the file anyway (to put the subtitles inside it), so I was just wondering if mkvmergeGUI is going to reject the file that dvdfab produces or not. |

| Do let us know,when you finish your test...

| Have tested usinng build 5.2.3.2 When using mkvmergeGUI it is still throwing up a warning about the ac3 track containing non-ac3 data, which may cause the audio/video synch to be lost. It also throws up a warning about the subtitle track, saying: "Negative timecodes are not supported in Matroska. This entry will be skipped" However, it is successfully muxing the files into a new mkv. The two files I tested (from different DVD rips) both played back ok, with sound in synch. This is progress! I'll do a few more over the next week or so and report back with any issues. |
