Yeah mate it was one of the major complaints way back when I started (the transition time used to be 2-3x what it is now - and yes I am an idiot ^_^)
I went through the 2-3k images and reduced them to 60frames just over a year ago and now there are 6k CGs so reverting them all is an absolutely mammoth job :d
Thanks for your comment buddy, I'm so glad it was a fun experience (for the most part!) so far :))
