16-9 standard def in red rushes?

[Grayton hevern]

Hi

I am trying to create standard def rushes out of red rushes, 720+576 anamorphic, the footage was shot 2-1 so the stretch option doesn't quite work, anyone on here come across this and how did you solve it? Thanks in advance.
Cheers
Grayton

We create non anamorphic QTs - 1024 x 576 Fit Width for 2:1 footage.
These fast import to Avid correctly
