I've been learning to use a couple of programs like Particle illusions, and while I have learned how to render a file to uncompressed AVI so that PI will import it, the file becomes distorted, especially during quick action. It's a horizontal 'rastering' or something. I hope this makes sense- it makes my little special effects sequence look even more unrealistic. Am I rendering the AVI incorrectly? Should I render the file from vegas as an image sequence? Any thoughts?
