GIF MovieI spent quite a bit of time, learned a lot, and had a lot of fun making this animated GIF movie in GIMP. I'd originally imagined using it as an icon, but to my dismay it's impossible to make anything resembling a movie, even in greyscale, that will come in under the 40k user icon file-size limit.

Alas.

Still, I'm extremely amused by this.

Nifty!

It's amazing how quickly you can use up memory with animations. Colour (or many shades of grey) seems to be the big culprit- my origami icon is something like 73 frames long, but only uses 3 or 4 colours, and it's about 37k.

You're right, the number of colours is the biggest culprit. With some advice from flipzagging, I managed to get a 100x100 version down to 37k.

Yay!

GIMP should allow you to control dithering and color depth, and partial frames, and so on. If not, you can use gifsicle.

$ gifsicle --resize-height 100 --optimize=2 --colors 5 cham.gif > cham2.gif




I resized it to 83x100, because I think the max size for an LJ icon is 100x100. Unfortunately it's illegible that way. If I left it at 100x120, I had to reduce color depth to 3, which ruined the picture.


erm, point being; that animation could be probably be done reasonably well, even under 40K. My crude attempt above is 37K.

If it worked from a pre-resized gif, it would look a lot better.

I used to do this sort of thing when 14.4 modems were considered fast.

I haven't been able to figure out how GIMP exposes the optimisation options, yet.

Hmm. I was originally going to crop it to 100x100, so let me try that and then see what gifsicle can do for me...

Ah, excellent. I had to go down to four colours, though, since apparently the 40k limit assumes 1k = 1000.
