Remember Me? Download free trial! Results 1 to 14 of Hi Does anyone know how to add metadata tags to an mkv or mka file? There is some information at the matroska website and on other pages but so far nothing has worked for me. I don't want any links, just an explanation please. Last edited by bat; 6th Oct at For windows computers you can add a little basic info simply by right clicking the file and choosing properties. However I think it varies by file type of how much info you can add.
Also you could try using mpchc or vlc. They may have the ability to add details to the files. They play most video and audio files but I never tried to add descriptions with them - could be possible.NVIDIA SHIELD TV - 120 mbps MKV Sample File Test (VLC Media Player)
Edit - you might also try makemkv. It can create mkv files but it might also let you edit descriptions on existing mkv files. Worth a shot. Donatello - The Shredder? Michelangelo - Maybe all that hardware is for making coleslaw? Originally Posted by yoda You have to try them yourselves.

The software I mentioned is free. I know for a fact the right click option allows access to title description and stuff but I think it varies between the different file types. The others are suggestions for you to try. I think the makemkv program will be your best bet to look into. It is specifically designed to create mkv files so I would assume it has info editing ability too.
I've been researching this for days and I can't find ONE program that can correctly edit or view Matroska metadata. Exiftool can see the first of the images and the metadata, although it's incorrectly formatted and still can't be edited. VLC can't see the metadata or images, and what's worse it pretends to let you change some media info but then doesn't actually save anything.
It's a nightmare.
Don't people care about metadata at all? The complete inability of what seems to be every program out there to deal with it is stunning. Without metadata you can't search clips. If you're recording your own clips, vital information like the timestamp will be lost you can't count on the filesystem stamp not to change. All I want is a permanent timestamp on my clips and if I'm real lucky, some keywords and a media player that can search them. But I guess that's too much to ask for. Originally Posted by Mr Hangman.

Maybe it can display the others too, but I'm new to the program. To be fair Matroska's TargetTypeValue system, while it makes sense on a high level, is perhaps confusing to figure out how to display.

The files presented here represent the minimum support a player should have to fully qualify as a Matroska player. Matroska can support any codec that is around. That doesn't mean softwares should support all of them. For various reasons softwares and hardwares can't always be upgraded to support all codecs around. But in the other hand there are a few safe codecs that are often found in Matroska and WebM that should be supported.
These codec can be found in various resolutions and features so even with the right codec support, it is not guaranteed that an implementation may support all the possibilities of a codec it is hardly ever the case.
This document will not cover codec details. But here is a list of codecs that are commonly found in Matroska:. It is important to note that audio can also be used in audio only files, usually with the. Those files should be handled as well, as long as the codec is supported. There are a number of features that are not essential to the playback experience but could really improve it, like support for tags, cover art, embedded fonts, segment linking.
There is also 3D support that is meant to grow in the coming years. Matroska should be able to support all the formats, but given the subject is really new, it's not covered by this suite of files. The sample comes from the Big Buck Bunny open project. It contains MPEG4. This file has different features that need to be looked at carefully. The main one is the global TimecodeScale in the SegmentInfo is set torather than the default 1, That value affects the values of the file Duration in the Segment and the Clusters Timecode.

The aspect ratio has also been stretched artificially to represent a 2. It contains H x pixelsand stereo AAC. The source material is taken from the Elephant Dreams video project.
It also removes 2 bytes off each video and audio frame since they are all equal. These 2 bytes have to be put back in the frame before decoding.As the popularity of Matroska is quickly growing, it is becoming necessary to define a set of minimum features players should handle.
As we are pushing old features like the header stripping, we realise a lot of players hardware and software don't support such simple features.
Probably because they never had a set of source materials to validate their code against. So we have remedied this with a set of 8 files meant to cover the basic features a player should support to be considered a good Matroska player. The emphasis is on the container support not on the codec. It's possible some players may not support Theora for example in the "live" test file, but it's always possible to generate a similar file with mkclean --live.
We strongly encourage developers and companies that produce Matroska players to test these files on their product and make sure they all pass the test. We also encourage users to test these files too with their players and report the non success they are having.
Let us know if you have any suggestion on how to improve this test suite or if you think something is not correct. On there was an update to the Wave 1 pack as test2. You can download the test files on SourceForge and also look at the Release Notes accompanying these files. Matroska Test Suite - Wave 1.

Thank You. Hey Pontakorn! I reached out to IMAX regarding a brand partnership. I am hopeful that they will see the benefit of providing the materials. Pingback: Anonymous.

Thanks for the uploads. I was wondering how I can get the video trailers included on the September Dolby Atmos demo disk. Challenge question for you: I have some. I also have the new Apple TV that has the Plex app installed. Hey I just had a similar challenge: to play an mkv video file with Dolby Atmos audio. Nvidia Shield and Dune Solo supports those formats.

Could be the source your playing the file though, the audio has to be passed though. Nvidia shield is a great player for audio pass though.
I have denon avr-xw 7. No, the MP4 container does not support dts audio.
The only way would be to convert the dts to AC3, but then you would not have dts audio. I have Onkyo tx-rz with the latest dts x update. What are you using for playback? I have never had success with VLC. I took a look at the user manual for your player. Check in the audio settings and see if the Down-mixing Mode is enabled. Since you are getting Neural X, the player may be Down-Mixing to stereo.

Whether you are downloading videos from the Internet or getting them from other people, there is a high chance that you will come across MKV files. It got its name from the Russian word for Nesting Dolls, matryoshka. The company also has a lot of resources on their websiteincluding a list of playback options.
As time went on, the format was improved and init became the basis for the WebM multimedia format. Contrary to popular belief, MKV files are not an audio or video compression format. MKV files are actually multimedia container formats. An MKV container can incorporate audio, video, and subtitles into a single file—even if those elements use different types of encoding. For example, you could have a MKV file that contains H. MKV container files were designed to be future proof, meaning that the files would not become outdated.
Matroska developers included several key features to make this happen, including things like:. The MKV container itself also supports almost any audio and video format, making the format highly adaptive and easy to use.
You have two main options for playing MKV files: using an MKV compatible media player or downloading the appropriate codecs for the media player you prefer.
Downloading and installing the program is easy if you follow these directions. Beware of going anywhere else, because a lot of crapware vendors have fake VLC download sites. Simply run the downloaded file to install VLC. The entire installation process should take no more than two or three minutes. Note that, while VLC does associate itself with all supported video and audio formats during the installation—including MKV—it does not register itself as the default app for those file types.
Of course, not everyone likes VLC player. Codecs are notorious for bundling in crapware or, worse, malware. The good folks at Ninite make it their mission to provide downloads completely free of any bundled nonsense.
