I have created the gif animation it should be below 1 mb, but there are some dots that are showing in the animation, they disappear when it's mp4. But i need gif, and also it should be with smaller size.
I tried to export as jpeg sequence in After Effects, and than open in Photoshop and export as gif animation, but is the same
Sorry, and let me be bruttally direct here, but this is one of those cases where you definitely have a wrong understanding of the limited capabilities of the GIF format. There are simply way too many colors to be accommodated in the 256 colors available to a GIF. the rings with the gradients alone could easily gobble up 64 colors to look smooth and then you haven't even accounted for the background. Whatever you have in mind will require a completely different approach regardless of what tools you use. This will never turn out any differently. If it's for soem web shop, you need to explorer how to combine multiple images and overlays in the web code and if that's not an option, then indeed you will have to embed it as a video format.
