Cinema's Matrix is a 3x4 Matrix. What represents the additional component in the Direct X format?
There is not way in Cinema because it doesn't make any use of it. Besides that, you need a
definition of how to convert the 3x4 Matrix to a 4x4 matrix.

FrameTransformMatrix {
1.0, 0.0, 0.0, 0.0,
0.0, 0.0, 1.0, 0.0,
0.0, 1.0, 0.0, 0.0,
0.0, 0.0, 0.0, 1.0;;
} // Unit conversion to Pandoras Box

From the Direct X file format snippet, it looks like you could just add zero values for the 4th
components (and 1.0 respectively for the position vector). If this is correct, you have your definition
and can now easily convert.

Take a look at the class 'Matrix4' in the SDK (might not be supported in Python though, but it is in C++).
