We wouldn’t want those Photoshop fanboys at work to discover that you actually use Gimp now do we… ) Bonus: Higher Frame Rateīy default, gimp will create your GIF at 10 fps. Obviously you need to check As animation, but the rest of the options are fine by default.ĭisabling GIF comment will not only save you a few bytes, but it’ll ensure your reputation stays in tact. Then once you’ve picked your file name, hit Export and this options dialog will pop up: GIMP, in its inexplicable quirkiness, requires you to “Export” an image instead of “Saving” it. They’re only opaque when something changes (like your tiny little mouse cursor). Most of them are almost completely transparent. Just take a look at the layers now and you’ll see what I mean: If a frame is exactly the same as the previous one, it removes that frame completely and just tells the previous frame to stay on the screen for longer. It only stores new values for pixels that change, and reuses information from previous frames when they don’t. What this does, is it looks at each layer, and deletes the parts of it that haven’t changed since the previous frame. This is the part that really makes a difference. But just note that this will increase your file size. If you’ve got a lot of smooth gradients in your gif, you might like to enable Dithering to reduce the most obvious of the banding. So to do this, simply go to Image > Mode > Indexed…Īnd choose Generate optimum palett e with the highest number of colours you can. Since GIF only supports 256 colours (unlike JPG and PNG which can handle 16777216), we need to generate a palette of the 256 most important colours used in our image.
You’ll see that every frame is now on its own layer: Step 2: Generate palette Then just select all the images in the sequence, and hit Open.
In fact in this example, the optimized gif is 2.5% the size of the unoptimized one.
gif file, but it’s going to be pretty huge. I googled a bit, and was surprised that I couldn’t find a good tutorial on how to convert an image sequence to an optimized GIF using Gimp. Sure, you can just export a bunch of layers as a.
