GIMP GIF WEIRD FRAMS UPDATE

Some animated-GIF programs have the ability to super-compress an animated-GIF so that it removes all unchanged pixels from each frame so that only the changed parts are stored. the palette in a variety of methods and with different algorithms.Īnother artifact you may be experiencing could be due more to your viewer than the file. It had numerous options to smooth, blend, dither, crush, etc. One animated-GIF program that I used years ago was ImageAlchemy. Depending on the graphics program, some provide more options, some provide less, and many of the options have different settings and modes. As you have found, you can use dithering to make an 8-bit image look better, but that is only one of the options. The artifacts that you experience are likely due to the limited color palette that the GIF format provides. Further, without seeing the actual artifacts you are referring to, we can only guess as to the issue you have because there are several different things it could be.Īnimated GIFs are not special, they are just a pile of GIFs displayed rapidly in a row. You did not provide any actual examples, so nobody can give specific details, only general guidelines. These might form a 2×3 tiling of the animated region, and you can have 256 colors in each tile, for a total of 1536 (6×256) colors.

You might have, for example, a sequence of six frames for each animation update (e.g., every 30 ms): one with a delay of 30 ms, followed by five with a delay of 0 ms.

Oh! On first reading, I missed the fact that your GIFs are manifestly animated.

Note: I have observed in the past that some image software - specifically, programs that don’t support animation - render only the first frame of such a file, and so do not produce the desired display. Remember I mentioned timing information? A GIF file can contain many frames that tile the overall image space, have different color maps, and are displayed with a delay of zero. The “gotcha” is that each frame can have its own color map.

This reduces file size by avoiding the need to duplicate the static portion of the image n times when only a small portion is actually animated. For example, you can have a 100×100 image, with a sequence of 50×50 frames, if all the animation occurs in a quadrant of the overall image. I may have the terminology wrong here, but the individual image frames can be smaller than the overall picture frame. That’s how animated GIFs work - like the more complex video representations, they can store a sequence of frames (with timing information). This might not be what you’re seeing, but, contrary to widespread belief, GIF images can have more than 256 colors.
