Hold your horses! :o)
Ok. First of all, you need to define if an animated gif is what you need. This depends on the image you have, the type of animation you want, and the place on where you are going to put the animation.
I am making a semi-random list of ideas of several options you have to animate stuff... especially for a web page, (Which I am assuming ...
Frame disposal method
The frame disposal method specifies whether to discard the current frame before displaying the next frame. You select a disposal method for animations that include background transparency to specify whether the current frame will be visible through the transparent areas of the next frame.
The problem is in the frame #1:
Check at ...
You cannot use antialias in transparent GIF images since it's only 8-bit, but you can fake it. When exporting using "Save for Web" use the option Matte to match the background color of where the animation will be placed. It adds a few extra colored pixels at the edges of the image.
The downside is that you can only match one color, so it won't work well on ...
The problem is that GIF has no alpha channel that can show semi-transparent colors. For that you would need to save as PNG24. With a GIF, antialiasing inevitably comes with a halo.
If you don’t want antialiased edges in a transparent GIF, then you should set the setting Matte to None in the Save for web Panel. (Alt+Shift+Ctrl+S).
I can't tell you what apps were originally used to create this, but general workflow-wise, this was a 3D model (high likelihood it started as a photogrammetric scan) created with a 3D DCC (Digital Content Creation) tool such as Modo, Blender, 3DS, Maya, C4D or Lightwave, with a simple NPR (Non-Photo-Real) edge shader applied to it, which then had a turntable ...
Because you are potentially dithering the image, and a dither adds more information.
My explanation about compression.
"Imagine you have a gradient, from left to right, from white to black."
That is it. I just told you the compressed version.
Here is the uncompressed version:
"One pixel white. Next pixel not as white, next one a bit darker, next one a ...
I was wondering if the GIF file format removed data which is shared between frames like a common background
Yes. But depends on the application that makes it.
Depending on the application you are using there are some options.
Maintain the previous frame
Save as a frame only the changing part. This is a bit relative because it is not pixel by pixel basis, ...
GIF compression is primarily in the colour table, rather than the image pixels - subsetting to a decreased total gamut and (depending upon export settings) can subset further to include definitions only for colours present in the pixels of the image itself; many GIF export compression algorithms do parse through an animated GIF, spot repeated pixels and omit ...
I have some artwork in illustrator that I would like to animate and get a gif.
The animated image should be quite small and the animation optimized.
Say I have a background pattern and I want to randomly move the elements ...
I'd do the following if I was making a sizable batch of these gifs:
Record the screen of me typing using any of the tools in Scott's link in his comment above
Import the clips into Adobe After Effects
Create a new composition for each clip and trim as needed
Then I'd use the GifGun After Effects plugin to export them as GIFs.
(There's even an option to ...
This has been a thing with Photoshop for a long and hairy time - the 500 frame .gif limit is hard-baked into the way PS handles these files... there are workarounds, and cludges.
You might consider looking at other software / tools to accomplish your task: AfterEffects, Final Cut, heck even QuickTime & put your output out there as .mp4 video file and ...
Illustrator places ok GIFs which have colored pixels and totally transparent pixels. I tried it:
The result is converted to RGB, but the transparency stays (the grey gradient below is for testing it)
Pasting GIFs from another program removes the transparency, so import with File > Place.
If you want only to remove backgrounds with no other reason to visit ...
Another simple method:
Add a layer, fill with white (or whatever color should be in the map)
Image>Mode>Indexed (you can use defaults). Since Gimp creates a colormap for the whole image it will keep the white for the all-white layer.
Delete the white layer
If you do the indexing explicitly (Image>Mode>Indexed...) instead of letting Gimp do it automatically then you have more options, and one of the options is to provide a palette. The problem is now to come up with an adequate palette, but you can get Gimp's help:
Open the RGB-mode image
Image>Mode>Indexed..... Tick "generate optimum palette" and ...
There are lots of programs you could make animations with, if I were you I'd just research some programs, there's probably some good free ones out there.
If you have Photoshop however, you can even use that.
Here's some instructions on how you could do this "lights off" effect in Photoshop CC, with a link at the bottom that includes screenshots.
You have to get back to the original image. The frames in the second image contain a trail of the previous frames. This is your top frame layer alone:
As far as I can tell the optimization done by Gimp is that pixels in a frame that are identical to those of the previous frame are replaced by transparency. The result is then auto-cropped. But the whole ...
The easiest way in Photoshop is making a Video Timeline Animation
Open the Timeline Panel and click the Create Video Timeline button
Put all the illustration objects at the origin position
At the timeline panel, expand the timeline of one of the objects to see the options
With the playhead at frame 0, click the Position chronometer icon to add a keyframe; ...
Not sure about "the best", since that's a very subjective judgement. However you can create HTML5 Canvas animations with Adobe Animate CC. It's mentioned on the Adobe Animate help website: Create and publish HTML5 Canvas documents in Animate.
Here's a brief quote from the page, just in case the link above rots.
Canvas is a new element in HTML5, which ...
If you want animated backgrounds which is vector form there are many aspects to do this but according to your after effect point, there are many uses of it.
If you thinking about after effects then its already good cuz of some core feature of After Effects like Motion Blur and Easy Ease will let you make animations flawless and natural. You can watch some ...
.png-8 bit and .gif both support 256 colours total. You're choosing colours outside their gamut, and so you're getting dithering as the exporter tries to match your colour - you can set different kinds of dither, and may find that "diffusion" is more random and therefor a bit less noticeable - or you could stick to colours within the 8-bit colour 256 tones ...
Using Save for Web or Export for PNG, GIF, or JPG images destined for the web is how you should be doing things. Save for Web/Export will often dump hidden data such as metadata which can enlarge the amount of kilobytes a file uses.
Another alternative is merely to Save a Copy. When saving, if a particular format is greyed out and unavailable, it is because ...
You need to add mask to your app image.
To do this you need to create new layer (mask) above iPhone mockup and make path of screen profile, fill it with solid color.
Then move layer with your app above mask and in Layers panel right-click on it and select Create clipping mask.
Below ugly fast example.
In addition to Danielillo answer:
I made a screenshot showing the two way to switch from Frames to Timeline mode. But this is not your case.
More: I made a CMYK file just to see if the icons would disappear.
More: When we first show the animation panel we have the option to choose between the two modes:
More info: See this post where it said something ...
The culprit is what I suspected in the comments. There are translucent pixels all around in various frames. Gif file format doesn't support that. Pixels are either fully opaque or fully transparent, so when you export that, it makes all of those seemingly nonexistent translucent pixels visible.
I checked this before the export by: giving the document a ...
I think what you want is to create an SVG file. There is an excellent piece of free Windows software that does this here: https://inkscape.org/
Then you need something that will run SVG files as animations. I use VideoScribe, which cost me a pretty penny back in the days when I used to get a study grant, but if you Google around you'll find plenty of apps ...
