Allow low-res viewing (1/8 & 1/16) while in 1080. Using 4K footage in a 1080 timeline is excruciatingly slow.
I have the option to downgrade resolution to 1/8 or 1/16 if I'm working in a 4K timeline but not in a 1080p timeline.
When working in a 1080 timeline, my source footage is still 4K, and system performance suffers the same as if I'm working in 4K. I need to turn that resolution down. Help! (Thanks!)
