Multimedia, AV Dirac is an advanced royalty-free video compression format designed for a wide range of uses, from delivering low-resolution web content to broadcasting HD and beyond, to near-lossless studio editing. The v1.0.0 version was released yesterday, and the new VLC version supports playback of .ts/.drc Dirac files.

RE[2]: Schrodinger

Well, looking for this implementation I can only find source code. I don't think that my Ubuntu's Gstreamer comes with it, or the command line encoder, and I can't find any info about your GUI either by searching online.

The package is gstreamer0.10-schroedinger, or something very similar to that. It's definitely in Ubuntu Gutsy, though I can't remember what version. Debian, Fedora, Gentoo etc have the latest version as far as I know.

After installing this, command-line encoding/transcoding can be done via GStreamer's gst-launch syntax, though I appreciate that this is only "easy" if you already know how gst-launch works.

More over, there is no encoder for Video for Windows, so it's impossible for me to edit something on Sony Vegas and export to Dirac. When a codec that's supposed to be so important is released, it better have some Windows encoding support.

They do seem to be lacking Windows binaries, which is probably something they should fix. There do seem to be DirectShow filters available though, once you've got it compiled.

And you say that there's an encoder somewhere. Where can I find docs about how to use it?

The wiki on is the main source of info at the moment it seems. For example,

gives a list of all the different settings for the Schroedinger encoder. There's also a (somewhat over-complicated IMHO) guide to encoding Big Buck Bunny into Dirac from the source PNGs, at

Please be more careful of what you write [you edited that out now]. I DID include the link to Dirac's site. It's the first word in the article.

You did, and I apologise. I thought I'd changed it back quickly enough when I realised my mistake, but apparently not ;)

EDIT: Ach. I meant Ubuntu Hardy, not Gutsy. Or 8.04, anyway. Stupid code names.
