One small clairification folks ... the code to be reviewed under this group is considered an embodiement of the spec and not an implementation per say.


9:15 AM
JD Vandenberghe (to All):

ok!


9:16 AM
Nick Shaw (to All):

Lean is good!


9:18 AM
Nick Shaw (to All):

I think we need a good reason to move away from XML. What advantage would a new format bring?


9:19 AM
Alex Forsythe (to All)

I agree with JD and Nick... I'm don't find XML particularly problematic


9:19 AM
Alex Forsythe (to All)

Tend to agree JSON is easier to read but not worth the trouble of moving


9:20 AM
Alex Forsythe (to All)

+1 to doug's point


9:22 AM
Scott Dyer (to All):

agree. was just something that was mentioned at some point and didn't want to dismiss any input. i agree with "let's not fix things that aren't broken"


9:22 AM
Rod Bogart (to All):

Staying with XML, we should confirm that we have a schema for CLF.


9:25 AM
Alex Forsythe (to All)

There's a schema in Annex A of the Academy Spec (S-2014-006). The spec is posted multiple places including the Virtual Working Group Workspace (https://aces.mp/CLF_SPEC_VWG)

I think it's important to keep integer. Integer is precise.


9:32 AM
Alex Forsythe (to All)

+1 to Rod's point


9:33 AM
Nick Shaw (to All):

6 decimal places of text float is sufficient to unambiguously code 12-bit int, or 16-bit half, is it not?


9:39 AM
Alex Forsythe (to All)

I think there's a point where enough digits of float can encoding an int but you get into issues of rounding on the way back.


9:40 AM
Nick Shaw (to All):

I did some testing, and I believe 6 decimal places means a 12-bit int can be converted and read back without rounding error


9:41 AM
JD Vandenberghe (to All):

great


9:43 AM
Nick Shaw (to All):

Is it a problem to multiply by 1023 or 4095 at parse time?


9:44 AM
Nick Shaw (to All):

The spec already acknowledges that precision will vary between implementations.


9:46 AM
Walter Arrighetti (to All):

Hi. I could make it in the end


9:46 AM
Walter Arrighetti (to All):

Sorry for being late


9:48 AM
Steven Tobenkin (to All):

Welcome Walter!


9:49 AM
JD Vandenberghe (to All):

yes


9:54 AM
Alex Forsythe (to All)

feels out of scope to me ... this is a lut format not an ACES implementation per say


9:55 AM
Chris Clark (to All):

Same. I suspect ACESclip will handle some of this and then reference a CLF, which should just be a LUT


9:58 AM
Alex Forsythe (to All)

Seems like the lut boxes would just need to make a LUT from the equations anyway
