[FFmpeg-user] C210 uncompressed video: horizontal offset

Hi everyone :)

I just received a 10 bit uncompressed file, encoded in something called
"C210" (*).
When I transcode or play it, there's a horizontal pixel shift.

Here's a screenshot:

Recent ffmpeg is able to read this file without throwing any errors.
Complete uncut ffprobe console output is below.

I couldn't find any information about "C210" online. Seems to be a
proprietary "dialect" of V210?


Any ideas how to get these files to decode correctly?
I've uploaded a sample file here:

Thank you very much in advance,
Pb
