Joe,
Thanks for your input. In regards to render time, I had the same experience with Tiffen DFX. On the project I used DFX on, I worked most of a day applying and tweaking DFX. When my client saw how long it was going to take to render, he opted to remove DFX and go with FCP’s 3-Way Color Corrector to meet his deadline. I don’t think there’s a way to get around long renders when doing hefty math, but your export/re-import method in FCP7 would certainly speed it up.
