If you are not scared on the command line and have installed ImageMagik (there's an OSX installer package on the web) you could do this. That was the 4th search result for "Quicktime to animated gif". The first 2 were for a perfect program to do this. For Windows 🙁
Thanks for that Mitthrawnuruodo it's what I've been looking for, have used it already and works fine for something that is freeware.
Don't know why this happened but after d/l it unstuffed as a Toast image file, so to get around this I used Get Info and chose open with DiskImage Mounter which solved the problem.
