MakeMKV 3:2 AR problem (still happening after 1.7.8)

[Sidrack]

SmartLabs tsMuxeR. Version 1.10.6 http://www.smlabs.net
Decoding H264 stream (track 1): Profile: High@4.0 Resolution: 720:480i Frame rate: 29.97
H.264 stream does not contain fps field. Muxing fps=29.97

I noticed this problem with two different titles. Both Blu-rays, Mortal Kombat and now Outland (1981). The movie is converted fine, but the only other content, which happens to be a SD trailer, is not.

The content is converted with a wrong aspect ratio.

I used TSMuxer to select the correspondent .m2ts file from the BD folder, and demux it. Then I used MKVToolnix to join the H264 / AC3 streams. Everything worked, for both.

To make things easier for you I am going to upload the MKV file with the wrong and correct AR.

Please wait for my response.

The above is a link to both the MKV file converted with wrong AR (MakeMKV) and the correct one with help from TSMuxer + MKVToolnix.

Like I said, the same issue happened with Mortal Kombat, The Movie. Is there something I should know about a few specific contents or is this a new bug I discovered?

I've seen this problem before, but only on DVD's. I'm sure Mike will take a look when he strolls by. It might be am improperly mastered disc, and it might be a bug.

[Sidrack]

The same thing happened again with another title: Hard to Kill (1990), a third Blu-ray.

And again, with a theatrical trailer (in SD).

MakeMKV seems to have a problem with this kind of content when it's the only featurette available in the disc, besides the movie itself.

It's only affecting them. I don't understand, this never happened before...

[Sidrack]

This bug also affected a 1 GB feature from a MK cartoon available in that Blu-ray disc. Again, the 3:2 display aspect ratio problem. I didn't noticed this before.

Another bug I saw with MakeMKV was when it tries to convert some subtitles from brazilian DVDs, and they became transparent (invisible for MPC-HC, almost transparent but visible if we use VLC PLayer). Using MPC-HC to playback, for example, Mortal Kombat (1995) brazilian DVD, you can see the movie subtiles are white and perfectly visible.

So it seems MakeMKV cannot read properly the subtitles in rare instances. And it's having problems to create MKVs with the correct AR with some extra material from Blu-rays.

Where is mike admin?

This bug also affected a 1 GB feature from a MK cartoon available in that Blu-ray disc. Again, the 3:2 display aspect ratio problem. I didn't noticed this before.

I have to ask you to do an additioanl step - please make a testdump per instructions at http://www.makemkv.com/onlinehelp/testdump.html for the title that has an aspect ratio problem.

Another bug I saw with MakeMKV was when it tries to convert some subtitles from brazilian DVDs, and they became transparent (invisible for MPC-HC, almost transparent but visible if we use VLC PLayer). Using MPC-HC to playback, for example, Mortal Kombat (1995) brazilian DVD, you can see the movie subtiles are white and perfectly visible.

This is not exactly a bug but rather missing functionality. The subtitles on DVDs use 4 colours and palette. One of the colours obviously must be transparent - technically it may be any colour in the palette, but most DVDs choose colour index 0. MakeMKV properly puts subtitles and palette in MKV file, but many-many software players either ignore the palette or assume that index0 is always transparent. I believe subripper always reorders colours so index0 is transparent (for compatibility), but MakeMKV just copies subtitle stream as is. The functionality to post-process subtitles is planned long ago, but now is obviously missing. So your MKV files are fine, but you have to wait for your favourite player or MakeMKV to be fixed.[/quote]

Sorry for the delay.

There you go, another extra feature, THE MAKING OF JAWS (2 hours length) with this problem, 3:2 Aspect Ratio, this time from JAWS (1975) in the american Blu-ray edition.

http://minus.com/mYpFiefQH/1f

Filename is JAWS_t02.tgz.

Warning: Before generating this file, I only selected such options:



In this case I didn't wanted alternate subtitles.

P.S. This problem happened with all, I repeat, ALL EXTRA FEATURES IN SD from this disc.

[mike admin]

Incorrect 4:3 aspect ratio is fixed in 1.7.7 . Thank you for submitting the dump.

[Sidrack]

Mike, the problem is still going on. I tested with two different Blu-rays, from Batman.

Here's a new dump:

http://mandandoprohd2.minus.com/mAyoZsFi0/

It's affecting all extra features. Again, the 3:2 Aspect Ratio. This one is from the theatrical trailer.

Note: The Blu-ray tested for this dump is Batman Returns (1992).

I also saw these messages while trying to open the Blu-ray, located in my external Hard Drive from Western Digital:



This is a MyBoook Essential External Hard Drive.

Despite this message, and this one:



I was able to save all extra features. However, I didn't tried with the movie. Instead, I used TSMuxer + MKVToolnix to do this task. And I will have to do this with the extra features if the bug is not fixed.

P.S. Specs from this theatrical trailer, taken from the m2ts file:

Please note this is a 16:9 SD video.

You need to instruct MakeMKV to never create a Matroska file with this setting:

Display aspect ratio : 3:2

When the Matroska file is created this way, MediaInfo reports:

Display aspect ratio : 3:2
Original display aspect ratio : 16:9

However, it should only report this:

Display aspect ratio : 16:9

[Sidrack]

Another Blu-ray with the same 3:2 AR problem... and this time, with no AnyDVD warning, it was read by MakeMKV just fine, and converted to Matroska.

JFK (1991) Blu-ray...

Affected (for example) a 2 minute theatrical trailer (from where I created the dump), and all other extra features. They are all with a 3:2 AR.

I created a new dump here, you can download from the Filefactory page:
www.filefactory.com/file/10jir17b32gb/n/title08.tgz

Note: this was tested in the last version, 1.7.8.

The BD review from this title can be found here:
http://www.blu-ray.com/movies/JFK-Blu-ray/1077/#Review

I wonder if mike or anyone else can really fix or look into this?

Matroska:


P.S. In this case (and only in this case) I wasn't able to bypass this issue by using TSMuxer + MKVToolnix, either. Maybe MKVToolnix (or TSMuxer) were not able to convert properly like MakeMKV. But so far they were able to, so this is a surprise.

[mike admin]

Please re-post the link for the dump as it got corrupted. The problem is clear - MakeMKV had two bugs. Bug (1) was that sometimes AR was incorrectly extracted for H.264 video. That was fixed. The second bug is that MakeMKV still sometimes fails to extract AR from VC-1 video. Both of your recent examples show VC-1 video. All that is needed to fix a second bug is a test dump and a little bit of time, so please fix the link for the test dump or just send the link to support@makemkv.com .

And to clarify - your video stream is correct, the only problem is that MakeMKV sets incorrect AR in MKV header, the actual video data is preserved as is. You should be able to set the correct AR with MKV header editor. Once the bug is fixed, you'll be able to remux the file with MakeMKV and get a proper MKV file.

[Sidrack]

Please re-post the link for the dump as it got corrupted.

Sorry Mike, it's fixed now, please check the previous post.
