Hi there, Just been looking to do much the same process myself… To output DPX sequence from after effetcs, select output format as “Cineon Sequence” – then inside “cineon settings” you can select file format as DPX.
For your effects, I can’t see a way of outputting split FX when you’r using layer modes etc. You could give the grader your project (pre-render FX layers so no plugin problems)- but it’s unlikely they grade in same software that you’re using…
Simpler would be for you to apply FX to pre-graded footage… then you can give back effects burnt into the picture… Grader could then do a final pass over your DPX sequence.
Hope it goes well,
Matt
