I've tried a couple of times to insert animated GIFS, with great success. It's a great feature as I can get some basic animation going without having to use fancy software.
However, some gifs that I'd like to use only have 2-frames of animation. I'm not sure whether this fact is the problem, but when I pop it into the timeline in MSP8, it doesn't animate. It also allows me to trim it to any size - unlike other animated gifs where it will only stretch to the length of one duration of the animation sequence.
So, I imagine there is a frame-minimum or something. Is it a known number? If I know the number, I can search only for gifs with a minimum number of frames and save myself the wait of finding out whether it will work
Here's a dragonfly animated gif, I was wanting to use, for example. This doesn't animate at all when you drag it into MSP8 - unless i'm doing something stupid - which often happens.
