Firstly I' accept there may not be enough info here for anyone to help me, but I'm not sure what folks might need to know in order to form a solution.
I rendered out a (20 second) clip from After Effects, which plays fine on my computers VLC player. However after importing it into Vegas (it was to be part of a larger project) all was fine until I rendered it out and there are HEAPS of horrible interlacing lines (artifacts?) on edges.
I've tried loads of different project settings and render settings including changing field order (none, upper first, lower first), de interlacing set to none and blend, but still the problem remains.
Because the clip plays OK from After Effects I'd assumed the problem was with my settings in Vegas, but perhaps this is not the case? I think I've tried most of the options available in Vegas, but I've pretty much run out of ideas.
Any help much appreciated.
