I’ve been reminded that this variant of TrueMotion exists too. What do you know, it’s actually somewhat like TrueMotion 2 NoModifiers.
Essentially it’s just another fixed packing scheme like Creative YUV, Cirrus Logic CLJR or Aura. You have left prediction, deltas coded with nibbles, the usual stuff (at least blocks in TM2 were coded similarly). The only peculiar thing is that it codes data by planes with chroma planes being coded first.
I hope to add detailed description of this codec to Multimedia Wiki by the end of this week and then forget about it again.
Samples and candidate to write decoder using wiki already exist?
Just ask around, it’s out of my scope.
I got _single_ sample, so I may now code it.
