I'm looking for a LogC to 709 LUT to load onto a HDLink Pro box. I found some LUTs available for download on the Arri website, but none of the LogC2Video LUTs are the format I need. Some of the LogC2Film LUTs are the proper format to load, like the .cube files, but they look just a little bit off. Does anyone know where I can get a LogC to 709 LUT in the .cube format that will load onto an HDLink Pro?
I was kind of hoping that since it should be just a generic curve for viewing that there would already be a version out there in the format I need. The last time I looked at the Light Illusion tools I was totally baffled. I downloaded the demo and could barely figure out where to begin. As far as I know I probably didn't even get that right.
Ive download the LUTs package on the Arri Web site and load them into Speed Grade On set 2010 and none of the LUTs ('ive tried them all) works, only a logC2film work, but i need to convert Log to rec709 also.
Anyone know why and if there is something special to do ? (ive drop the Luts in the Luts folder in Speed Grade and they appear in the software.

Nice to see you here also,
I talked to Iridas, and I heard that they are planning on a new set of LUT's for Alexa soon ( IBC starts on 10 Sept) that should fix that issue.
If you and Jay would send me a private message the Arridigital forum with your email addresses- I will send both of you the rough ones I built I have quickie Day and Night versions that are not full REC709 compliant.

And I also want to add that I did download the latest software demo from Light Illusion and I now find it easy to understand and use. Especially for converting the format of the LUT. It probably has more to do with me understanding more about LUTs then it does to anything else.
