I am using XP pro. Of course I did not read the tutorial....I just jumped right in and started using. I got the main picture in, but when I want to animate it myself by say putting Xmas light colors on it like twinkling stars(doing it coloring pixel by pixel) in certain spots(like on points of a building) over the course of say 30 frames) the computer was initially alright with that and took the information in accordingly and saved each frame as I "x'" out.
Processing the information a little bit slower when I got to be 30 odd frames of editing.
Then I added the "sparkle" effect. It started to get unhappy with me. Especially when I went back to my X'mas lights to make some modifications to them(color changes and size for better effect) It finally crashed. And on restart I see I have the basic "christmas lights" that I added, but not the touch ups or sizing that I did them.
I was also noticing that parts of the background which I was doing the work on was getting white pixels. Maybe in the range of 200 or so.
Now would this be a capacity probel with my PC(1.04Ghz Windows XP pro SP1 PII) I cannot get SP2-that is not an option.
I work with what I got.
