This is the way my video looks when put in Sony Vegas after rendered from after effects.
This is the color of the original pre-AE footage.
This is the same frame as the first but in quicktime after rendering.
I've tried rendering in multiple file formats. I've tried rendering with "preserve RGB". It seems the problem is after it is rendered, Sony Vegas does something weird and I am at a loss. I have no clue what to do. I need help urgently I am on a TIGHT deadline.
Also, if you rendered the original clip out from Vegas with some effects applied in your timeline and are now replacing that footage, make sure to disable/remove the effects so they are not applied twice.
