In PP I have source media on track 1 and AE lower third scrolling text on Track 2 (above track 1). Everything looks prestine on PP program monitor and on external production monitor. Export timeline and severe banding occurs.
I have attempted exporting AE file in a number of different file types without any difference. I have also attempted exporting PP sequence in a number of different files types without success.
