Here is a proposal on how to store Apple's ProRes in Matroska. The
technical info on the codec can be found here:
http://wiki.multimedia.cx/index.php?title=Apple_ProRes#Frame_layout

The IDs are as follows:
    Apple ProRes 422 High Quality: V_PRORES422_HQ
    Apple ProRes 422 Standard Definition: V_PRORES422_SD
    Apple ProRes 422 LT: V_PRORES422_LT
    Apple ProRes 422 Proxy: V_PRORES422_PROXY
    Apple ProRes 4444: V_PRORES4444

Each Frame (in the Matroska sense) is composed of the Frame Header,
the Picture 1 and Picture 2 (when necessary).
If these data are always the same, the header compression in Matroska
can be used to strip it and save a little space.
