@cpm, I was able to complete the HDR InfoFrame Metadata calculator in the spreadsheet. I added a new tab “HDR InfoFrame” that follows the same approach as the original model with the appropriate mods for the HDR InfoFrame metadata calculator. I also cleaned up the previous two tabs “Original” and “Player Led (HDR)” for updating the graphs and a few cells that were inactive. I also expanded the choices for Color Space to include a CUSTOM option that you can change the values to your liking in the matrix. For the HDR InfoFrame Calculator I also added other White Points besides D65 including a CUSTOM option as for the Color Space.
I am sure there was a reason that for the VSVDB block the spreadsheet had pre-defined nits values (you could not just put a value you wanted). For the HDR InfoFrame Metadata Calculation I used a more free form way where you just put any value you want as long as it is part of the CTA-861.3-A standard - which means you can go higher than 10000 nits and lower than 96 nits (even though current technology is limited to that). I could add limits in the future but thought that this will allow folks to test extreme options as some have done in some forums.
Enjoy your holidays!
