![]() The one made using Photoshop appears to be better quality. I uploaded my GIFs, one made using Photoshop and the other made using GIMP. If I open a GIF from the Internet using GIMP and then save the GIF, the GIF appears to have the same exact quality as the original GIF from the Internet (see first two attachments). Single colormap, maybe that is the problem. Remember, open any gif animation in Gimp and it reduces down to a Will make for banding in a gradient as with your first example. ImageMagick each frame can only use colours from that colormap. The essence is, in Gimp and other applications such as Use the Gimp menu: Windows -> Dockable Dialogs Image, which might well have 256 colours. The colorcube analysis applies to individual layers, not the whole I never open a GIF file using GIMP and edit the file. I import frames into GIMP that were exported using VirtualDub. Scaling down and when a gradient is involved. I was trying to make the point that an animated gif is a finishedįormat, not meant for editing and you will get degradation especially Rich: I have confused you with the colorcube analysis - sorry. Remember, open any gif animation in Gimp and it reduces down to a single colormap, maybe that is the problem. There is one utility gifsicle that will assemble such a gif. Maybe Photoshop does that, I do not know. It is possible to have an animated gif with a colormap for each frame and overall have more than 256 colours. ![]() That will make for banding in a gradient as with your first example.

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 Please log in to manage your subscriptions. ![]()
