Hey I have a video I would like to be made into a gif.

Sorry I couldn't think of a good forum to put it in.

Any size constraints (animated gifs from video get big if you don't limit the resolution)?

I'll have a go at it now

edit: sorry, stupid proprietary formats, can't get the .mov to open in virtualdub

What kind of video file will work, I can convert to anything.

Nah, I got this. Do you want the entire video gif'ed?

Edit; dimensions, as well.
