Dave, I edited complete film online, red one footage. I did VfX on original footage, rendered them out 4444 and replaced on timeline now other than VFX shots my timeline is online. Now I will divide the timiline to 4 parts and then I will export each part to davinci and render out to 4444 after grading. When I will have complete movie rendered out to 4444 in 4 parts then I will export required formats including DCP drom those 4444 parts.. What do you suggest Dave?
