Hey Kevin. The images are double the final resolution of 800×450. So, twice the resolution, four times the area. I can preview the whole timeline at full resolution. RAM preview at full resolution crashes.
The nature of the crash is that a static hour hand comes up and AE stops responding or indicating any kind of action.
And, if it helps, AE freezes no matter what kind of rendering I try to do. I’ve tried JPEG and TIFF image sequence exports, MPEG, AVI, etc. Always freezes at the same place.
