Color bar distortion in Illustrator
on Apr 27, 2010 at 9:55:28 pm

I am using CS4 to create streams for automated testing of video equipment. When I build color bars in Illustrator and export them in bitmap or .png files to Mazanita software to turn them into
video transport streams, I see curvature in the lines connecting the color bars on the vectorscope. If I export them as bitmap or .png files and play them with Windows Media Player or VLC I see the same distortion The bars are in the vectorscope boxes, but the connecting lines are curved, exhibiting delay. If I import generated bars to Premiere and follow the same process, the vector lines are straight. This leads me to conclude the problem is in Ilustrator. Has anyone else noticed this issue? I realize this is probably not to important in production, but it seems strange. The curvature is worse in HD video than SD video.
