I’m curious as to why you’re stretching the horizontal resolution of your clips.
if they’re 1440 native, are you dropping them into a 1920 wide comp?
Wouldn’t it be better to keep them at 1440, using pixel aspect correction in the viewer.
Are they going back to f.c.p.? if so, keep them at 1440 with their native p.a.r., and f.c.p. will still know how to display them correctly.
Also are you working in 16 or 32 bit?
Why not render to ProRes HQ rather than Animation?
