David,
The 4K is the output file which will be JPG2000 in this case. The footage is all raw DSLR stills.

I do not have direct experience with it but you may want to convert that 4K file to Cineform format: I understand it is much less processor intensive and still be visually close to the original quality.

I’ve got a client supplied AE CS6 project file that is 1.5Gb – takes an hour and half to open. It’s a 37 minute 4K film that I’m creating a DCP. It’s already reduced. It’s created from DSLR pics – 2.6 TB of RAW files.
Any under the hood performance tweaks that might help AE handle the file better? The render machine I have does not have a SSD unfortunately which would help a bit with load times it appears the load is mostly checking the 2.6 TB of RAW files.
A film is – or should be – more like music than like fiction. It should be a progression of moods and feelings. The theme, what’s behind the emotion, the meaning, all that comes later.
