in Boris, go to edit/preferences & the “local project” tab. always make sure “better quality field rendering” (no aliasing) is selected… also if you have flicker probs, select 1:2:1 deflickering as well. I’m not sure about other versions of Boris products but in mine (RedGL 3.0.1), even though it says in that tab “values set here will be the default for all new settings”, the only one that “sticks” is the better quality field rendering setting… so I always make sure 1:2:1 deflickering, etc. is set before I export, OR apply if using as a AVX plugin in Avid.
hth,
