You can't sort out the blurry dots. GIF images have 256 available colors, and getting "between" colors leads to graininess such as you have experienced.

Gifs typically do have a very low color palette as Sumiki points out.

 

Perhaps speeding up the default wait between slides in Powerpoint will speed the gif up a bit, but I've only ever worked with pptx files in Powerpoint, so I do not know how the gif features work.

 

I suggest using GIMP for gifs. Just make each frame its own layer, then save the gif as an animation. From there you can set the playback speed as you like. GIMP is also very good with gif colors, but expect to see some color loss (hopefully less graininess though)

Seconding the recommendation for using GIMP; it's free, quite well-featured, and does a very good job of dealing with GIF's limited palette. It won't be perfect, but it should avoid at least some of the graininess you're getting now (for comparison, most of my sig banners are GIFs made in GIMP (albeit saved as PNGs so they could be well-compressed); very few of them have notable graininess, despite the originals going beyond 256 colors).

Just here to throw my support to GIMP as well, and applaud you for doing this.

 

I made this with the MNOLG kit in GIMP and I can't see any grainyness.

 

That's the result when made in GIMP, it's a lot better for graininess, but the rocks in the background seem to have developed a mild rainbow effect. Thanks for the advice.

 

@Roablin - Your collection of MNOLG stuff never ceases to amaze me, that backwards view Pakari is bound to come in handy. I imagine there's no colour loss because there are only 9ish shades of blue, a couple of shades of grey, and the white background.

What I actually recommend, in addition to using THE GIMP, I recommend using animated PNGs. Good file-size, animated, and no colour loss, all in one package. =)

Never heard of those, but I just looked them up now. They sound good, but don't seem widely supported by browsers.

You are right about that, I never considered that I was only using one color scheme.
