I tried changing the bit depth to 32 but I’m still getting aliasing around the edges of the vignette where the black and blue solids are meeting.
NOTE: The aliasing is noticeable on the 4:3 standard definition television I am previewing with (through a Canopus box) and NOT on my computer monitor. Since I will be exported to an SD format on DVD, this will be an issue.
Any other suggestions?
