Understanding MKV files

[jagabo]

but when I switch to mkv like someone here suggested on another feed the BD690 recognizes but states incorrect resolution?

The difference between MTS and MKV is the way the data is arranged internally. So simply renaming an MTS file with an MKV extention doesn't make it an MKV file. Putting a Ferrari prancing horse on the hood of your Honda won't make it a Ferrari either.

Yea, I did not understand that either. All it did was to allow the BD690 to recognize the file (name) but that was it. Stupid me for even trying! We just need LG to recognize mts and all will be happy!

Why don't you try converting your mts files to mkv with Xilisoft? I have done so and the quality is excellent, probably quite the same.

I'm wondering how a file looks for other segments?

I downloaded a file vid1 that is in C:\dir1\ which links to another file vid2 in a subdirectory C:\dir1\dir2\ and it works if I move that file to dir1 (so both files are in dir1). I figure that it'll work as long as it's in the same directory or any subdirectory of dir1 but it also works if I move vid2 to C:\ or C:\dir3\ or C:\dir3\dir4\..

Huh?

You can use TsMuxer to demux the MTS file to elementary streams.

I've had a lot of trouble with TsMuxer and demuxing .mkv files, lately. Does it choke on the same kinds of files with header compression?

Unfortunately, .mts is an MPEG-2 container and since everything is going to MPEG-4 standards, I doubt that many of the MPEG-2 containers (.mpg, .mpeg, .vob, .m2ts, .avi, etc.) will be supported by much of anything anymore. .mkv and .mp4 are the wave of the future..... at least until the next latest and greatest.

Yea, I am just going to conert my MTS files from the JVC HD cam to MPEG4 HD using Xillisoft. It just sucks you cant go from CAM to BD690 with no conversion. Oh Well.

Hey, try demuxing with TsMuxer and then just remuxing into an .mp4 with YAMB. I would think it should be a quick 2 minute process. You may even be able to open the .mts file in YAMB and just let it remux the file in one step. I do this with .mkv files all of the time.

or

Now that I'm looking at it, I would demux with TsMuxer and remux to an .mkv with mkvmerge. I just noticed that the LGs support .mkv. Most devices won't playback an .mp4 with and .ac3 (Dolby Digital) audio track, but most devices that support .mkv will playback an AVC/ac3 in the .mkv container. Couple more steps, but it will be a huge time saver and you won't lose any quality through conversion.

To those that are following this thread and have had problems with mkv files, here are some tips:

1) If you use MKVmerge up to version 4.0 there shouldn't be any compatibility problems with most players, but you should try it.

2) If you still want to use MKVmerge's later versions, here's what you should do:

a) File->options> click on "Disable header removal compression for video and audio tracks by default"
b) Select each track (video, audio, and subtitles)
c) Select the Extra Options tab
d) Set the Compression option to "none"
e) Start muxing

Both ways 1 and 2 worked for me and files play fine on my LG BD390.

Huh?

I think coolxal is referring to 'ordered chapters' in an MKV. I haven't looked into it, myself, but I did find this post on VH that looks like it may have some links to more information: https://forum.videohelp.com/threads/300316-Creating-Ordered-Chapters-%28Haali-MKV%29
(the replies to the post, actually)

Another issue on trying to understand MKV files: DTS tracks.

Maybe this is a problem in how my LG BD390 player deals with mkv tracks, but sometimes there are some glitches in the audio that make it impossible to listen to.

It sounds as if there was some "dirtiness" in the track now and then. Converting the DTS track to AC3 5.1 usually solves it, but I would like to understand why it happens.

The re-merge of mkv files with DTS tracks also seems to cause problems, and on this I wonder why does it happen and if it can bu cured. That is the original file plays fine, but when merged it has audio glitches.

Any clues?
