![]() Use the Gimp menu: Windows -> Dockable Dialogs -> Colormap. For a color-indexed image look at the colormap. The colorcube analysis applies to individual layers, not the whole image, which might well have 256 colours. I was trying to make the point that an animated gif is a finished format, not meant for editing and you will get degradation especially scaling down and when a gradient is involved. I have confused you with the colorcube analysis - sorry. It is what is used in all the GIF-making guides.īefore coloring (237 unique colors) tumblr_inline_n77viq1h3y1rm9cxl.gifĪfter coloring (250 unique colors) tumblr_inline_n77vf1kfE91rm9cxl.gifĮven after applying a pre-made PSD containing colors and effects forĪnime GIFs my GIF still has only 65 colors, no where near 256. ![]() But I need to get it right in Photoshop first. Eventually I would like to translate this to GIMP. There is no telling when it will be finished. Photoshop CC is taking ages to process the save dialogue. I am going to apply it to the GIF I am working on and see what happens. psd file containing colors and effects for anime GIFs. Of course, this led to an awkwardly colored and bright GIF due to significant differences between the source frames, but the purpose was to simply see how many unique colors I could achieve. I followed the aforementioned guide exactly and the most I achieved is 83 unique colors. Even the GIF that hasn't been colored has far more unique colors than my GIFs after they have been colored. Particularly, I used the following tutorial. Every tutorial I've read has me scale the frames down first thing. Rich: I scaled the frames down before doing any other editing. Looking at theĪnimation that works quite well. I think more thanĥ0% and loss of pixels really starts showing, but again that dependsĭisguising the defects with noise is a clever idea. Results scaling down using a pre-blur (gaussian) is usually What wouldīe better, is using the pre-gif graphic work.įrom those screen shots, the image size is scaled from 1250x720 toĤ50x253 = 35.14% that is a lot of information lost, regardless of the It might be a new projectįor you but it looks like it is based on an existing gif. I think you will need a lot of tinkering. Do all your work in RGB, save as an xcf then a final export. Remember a gif is a finished format, not meant for editing. To convert that to color indexed you need to apply dithering: attachment05 Scaling that by 50% with interpolation, gives a better image, smoother transition between the colors: attachment04 Taking that same frame as a png, nominally looks the same:attachment03 Scaled 50%, no interpolation, a blocky image, loss of colors: attachment02 ![]() When you scale an indexed image, there is no interpolation. Working with one layer only as an example. Why on earth do my GIFs have soįew colors (5 and 11)? For some reason, my GIFs are losing far tooĪ little more information from an earlier post - you are scaling the image In the first animation box, you can control the brightness area by dragging the corners of the brightness rectangle and in the second animation box, you can see and download the final GIF with the changed brightness.Please log in to manage your subscriptions. You can observe the brightness changes in multi-frame animations frame by frame or you can stop at the first frame to see how the brightness change affects one static frame. The two live animation boxes show GIFs before and after the brightness change. Similarly, if you set the brightness to 90%, then each RGB color channel is multiplied by 0.90 and the GIF becomes 10% darker. This effectively makes a GIF 10% lighter. For example, if you change the brightness to 110%, then the value of each color channel (RGB – red, green, blue) is multiplied by 1.10. If you leave the brightness value at 100%, then the GIF won't change. To darken the animation, enter a percentage value less than 100%. To lighten an animation, enter a brightness value greater than 100%. The brightness area can be either the entire GIF or a user-selected region on a frame. It increases or decreases the amount of white light present in the pixels. This browser-based program makes an animated (or static) GIF file lighter or darker.
