I only have some hdr video sample downloaded so I can't test exhaustively this script, but it produces reasonably good output.
There's at least one issue:
I use the resizer in the core for conversion from bt.2020 to bt.709 and from the github
"Note that "z" is not a color management system and should not be used to perform drastic contrast or gamut reduction, such as BT.2020 to BT.709."
