I set my still PNG images from an animation that lasts 2 seconds from 3DS max to .04 "still image length" in Vegas preferences. That sets all 60 stills squished back to back that lasts 2.5 seconds. When I add more time to the still image length, thus making the animation slower, it transitions fine.
But when I try for the scheduled time, around 2 seconds or lower, when the motion begins in the animation, you can see blinking when each new still comes up.
Is there a value I can change for smooth non-blinking transitions?
