How to load custom LUT´s on camera using ArriColorTool

[saavedrarolan]

Hi, I´m having trouble converting custom lUTs/looks to the Alexa mini format.

In a past project I used Pomfort´s Live Grade to convert a .DAT LUT to .aml, but right now I don´t have a working license with me and I understand there has to be an easier way using the Arri Color Tool.

With the Arri Color Tool I´m trying to load a .cube (I´m trying to use one of Davinci´s default) but a windows pops up saying "An error occured while reading the cube lut".

Can anyone give me a clue on what I may be doing wrong? There´s any limitation on the lut format it allows to work?

Also, I´m interested on any alternative; any third party software that you people usually use to convert lut´s.

Thanks a lot!

Daniel.

I think I´ve just find the problem. For some reason, when I try to load the .cube default LUT´s from Davinci, Arri Color Tool isn´t able to load them, but if I charge the same lut into a davinci´s node and then export the correction as a 3dLUT, then it works fine...

Don´t know if this has any sense but it´s happening...

Either way, If anyone could give some feedback on how they use LUT´s and how they convert them when they have different devices, it could be an interesting topic!

Hey Daniel,

can you post both versions of the LUT here or mail them to digitalworkflow@arri.de so we can figure out why it hast been blocked?

Thanks,
Jan
