ExifTool can't read camera and optics info tags from a Sigma FP's .mov file

[newillusion]

Hello!
Now ExifTool can't read camera and optics info tags from a Sigma FP's .mov file.
If i try to specify -b -u switches in a command line, ExofTool displays some parts of this info, but is it occluded by huge garbage text.

Is it possible to learn ExifTool to understand SigmaFP's video attributes tags?

In attachment is small exampe of the video,  produced by a Sigma FP cam:
