# Please help MarkP0rter.
what do you do to keep your GIF animations so small?
i really dont know what programs you are using. if i export an animation with only a few frames out of after effects with say 128 colours the file size will still be too big for the front page and Imageready doesn't make it much smaller either - only look worse. So so far I've never figured out what you use for all those quite LONG gifs on the front page.

# surey gaz'ing Mr Porter would be the first step?
are you ridiculing the chap or trying to annoy the board nazis?

*edit - ah, sorry I thought someone was looking for Mark Porter asking for assistance.

Ok, what I suggest is that someone on talk replies saying, why not ask this on mainboard in an existing thread, like everyone else soes who has a problem and wants a reasonable (or sometimes amusing) reply

# 128 Colours is insane.
I use FREE ULead's Optimization Wizard to get it down - start with 64,
then work my way down through 48, 32, 24, and if it's that bad, 16.
Some people use scanlines but I don't like that, it makes them
look like they're being played on an early TV prototype.

50+ frames, 32 colours per frame, under 400k

Good luck

# I was beginning to think that
the idea was not to let on what any of us use.

However, I use the GIF optimisation on the Gimp.

There are basically two steps:
# take out what is the same in consecutive frames so that you don't have to redraw it; and,
# take down the number of colours from RGB to 255/128/64/32/24/whatever.

You can do them in either order but if you remove the image redundancy first (ie, get rid of anything that doesn't change) then when it comes to reducing the number of colours, the dithering routine will only work on what it has and produce a smaller file.

If you reduce the colours first and you have something high up in the image that changes, the dithering routine will dither differently right down to the bottom of the image so that when you come to take out the redundancy, it will keep large portions of the image that weren't moving in the original but now have dithering on them.

Also, if you need to change the frame rate (like if you have times when nothing is happening) then just make those frames longer. The following has one frame that lasts 5 seconds. It had to go with jpegs so it has a lot of colours in it.

# Sometimes you need to plan your animation
so it will be easy to optimise later.

The less movement between frames, the better. The less frames the better - if you have many identical frames next to each other, delete all but one and set a delay on it instead. Take out all the frames you do not need - remember the joke is more important than a perfectly smooth finished product.

Take the number of colours right down and try adding one in at a time, to see how it affects the filesize. Same with dithering - add in a little at a time, until the filesize gets too big. Add as much lossy compression as you can get away with, keeping an eye on filesize all the time.

Sometimes you have to accept that animated gifs are really not intended for, and not suited to making long animations. Maybe try making a shorted preview version you can put on the board and link to a bigger version. Or upload a long, full colour, pretty version to youtube or similar instead - then you can even add a soundtrack.
