DivX Showcase - Big Buck Bunny & Elephants Dream


On the DivX homepage both Blender Foundation opensource movies (Big Buck Bunny and Elephants Dream) are being showcased, with links to Blender sites and the movie downloads to demonstrate the free DivX 7 video player.

The DivX website homepage can be viewed here.


  1. So how exactly did they render an animation into an MKV container? Did they use a modified build or did they just compress it to MKV in post-pro? (with like VirtualDub or something)

  2. Hi all!

    I work as part of the DivX community team. Big Buck Bunny and Elephants Dream have both been downloaded hundreds of thousands of times and I have to congratulate the Peach and Orange open-movie teams, as well as Blender Foundation and all of it's contributors for their fantastic work!

    advs89: That's a good question :) I actually encoded all of the showcase content using the DivX H.264 CLI Encoder Alpha 1, a free download from (a free DivX Labs account is required). The lossless PNG sequences were passed to the encoder using an AVISynth script via the ImageSource() function and the result was a raw H.264 video bitstream. Additionally the stereo and surround FLAC audio sources were converted into AAC streams and some of the subtitles for Elephants Dream into SRT format. Using the localized scripts for Elephants Dream I also created a list of chapter points (the chapter names will show in a future version of DivX Player), and some basic metadata and all of these source components were fed into MKVMerge to produce the final files.

    The DivX 7 playback software is free and you can either use DivX Player or a third party player to watch as we've included DirectShow filters to extend support for the format to most third-party players. Our H.264 decoder has very high performance so most systems should cope well with the HD playback.

    Can't wait for the next open-movie ;)

  3. I got into blender like 2 weeks ago, when I first saw Big buck bunny. And the idé of this open source 3d program is so clever. Sins very many ppl likes making animation/games/pictures i see a great potential in this, and thats because they can easly help devloping blender with new featurs wich they program.

  4. @Alastair: I noticed on the divx website it's not obvious whether the codec is real free software with sources available or freeware with closed sources. I think it would be helpful to mention it, ie when you say free, you could add sthg like (for non commercial use / closed source).
