I have produced a number of animations varying from 10 to 20 seconds in length, on a number of animations there are quality issues such as image flickering during animation and also cad data out of view breaking into the animation. Please see attachment. For animation export I am using presenter, 1024 x 768, render quality = high, 20 FPS and export as PNG. The PNG files are then compiled together using Moviemaker. On the attached file you will see flicker especially on the white/grey transport boxes and also black line breaking through at ground level. Thanks in advance for any comments.
