I am working on a annimation rendering and have found that if any compression is used within the .avi annimation saving settings the white surfaces (simulated white walls) end up a little blotchy especially with movement. Without compression the file is fine and clear. Problem is that an 8 second video uncompressed is 4Gb which is too large for anything to open. If I shorten the video to 2 seconds media players can open it. This is okay except the end video is to be a minute long so that will require 30 videos to piece together. There has got to be a better solution.
Let me know if anyone else has had this problem and has a fix.
