Oliver,
You are correct.. We (luckily!) shot a test and got the LogC 422 footage.. It was also pretty compressed.. We are shooting this morning, and switched to 422 709 (no FCP here, all avid) and everything looks great..
Once I did find out the problem, I went to Arri’s site and used the web based LUT generator.. That definitely helped, but I never got the rich colors we saw when we were shooting.. I’m colorcorrecting in AE.. Just for future reference, is there something I’m not doing?
Thanks!
