There is a Title field and that's what many current players do read as the video title. It does see each level of TargetType as a separate tag so if you don't need add a new level you should be able to get by.Īnd because this can't be simple, note that there's also header information that is separate from tags. The only way I know to edit the tags is with "Matroska shell extension" for windows. You can use mkvinfo GUI to view the tags. You could also attach it directly to one of the streams, but to me it doesn't make sense to do that most of the time. If you're using mkvmerge GUI, click on the Global tab and where it says "Tag File" choose your xml. To my knowledge you can't (for now) add tags to an existing file or even edit them later, you need to mux a new video (one exception I'll get to). Now that you've written your tag file you need to use mkvmerge to attach it to a video. There's a link on this page to download the actual. Matroska provides some sample tag files that should demonstrate how you might want to use TargetTypes. The above example doesn't specify it so it goes the default level of "50" (which for videos equates to a TV show or a Movie. TargetType indicates whether the following metadata applies to (I'll use a TV show as an example) the whole show, the season, the episode, part of the episode, or just a scene or even just a shot. The other thing you have to watch out for is the TargetType. If a media player that properly fetches tags is ever made, you'll want to be using official tags as much as you can. You don't need to do anything special, it's just that players won't know what to do with them and will probably only be able to show them by listing the full tag. The TagName should if possible be one of the official tags listed here:Ĭustom tags are possible. That's just a basic example with two tag items. Several actually.ġ) There's no simple GUI to tag with for now, you need to write an XML file.Ģ) The Target system gives some added flexibility but also can make the organization of the tags confusion.ģ) Only a few programs seem to be able to read the tags, and those that do just unintelligently spit them all out, rather than finding and neatly displaying the official tags.įirst make a text file and name it name.xml (pick whatever name you want, but make sure to have the. I've figured out how to tag them, but there's a catch. 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. And yet the standards are well defined, WHY AREN'T THERE PROPER EDITING PROGRAMS!?!?! AAAAARRRRGGGHHH!! 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). 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.ĭon'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. Exiftool can see the first of the images and the metadata, although it's incorrectly formatted and still can't be edited. mkvmerge shows that there are images and that there is metadata, but the metadata cannot be viewed or edited, and the header editor shows no trace of it. Several programs recognize that there are attached images but have no way to view them. CoreCodec has a sample file that is supposed to be correctly formatted here: I've been researching this for days and I can't find ONE program that can correctly edit or view Matroska metadata.
