for all ppl who are making animated gifs or want to start make one, there is simple way for extracting frames instead Virtual dub and all other programs. You can extract frames using MPC "alt + i", simple, fast

. I use that method over a year now and I see no one mentioned it yet so hope this helps new gif animators

...when u extract all frames using MPC just use Adobe Fireworks (I use CS3, simple version :3) to make animated gif

...easy and simple...well this is my method

. Also I use Gif Optimizer v1.0 to minimize gif size and not quality
