AnimatedImage

Represents a collection of Image merged into an animation

AnimatedImage[{__Image}, opts___]

AnimatedImage[File[_String], opts___]

Options

By the default is 12

Import .gif as usual and supply to AnimatedImage as a list

AnimatedImage[File["yourGif.gif"], FrameRate->24]

Generate raster images

t = Table[
  With[{h = h}, LinearGradientImage[Hue[# + h, .5] &, 50]], {h, 0, 
   1, .1}];

AnimatedImage[t, FrameRate->24]

or from imported GIF

AnimatedImage[Import["anim.gif"], FrameRate->30]

Another example

AnimatedImage[Rasterize[Style[#, 40]] & /@ Range[0, 9], 
 FrameRate -> 6]

You can wrap Animate, AnimatePlot, AnimateParametericPlot expressions with AnimatedImage to rasterize them into the series of images:

AnimatedImage[AnimatePlot[Sinc[x z], {x,0,4Pi}, {z,1,5}], FrameRate->60]

where it is extended with options alike Rasterize

FrameRate playback speed (does not affect rasterization)
"Window" by the default is CurrentWindow
"ExposureTime" sets waiting time before each frame is captured. By the default it is Automatic and the actual values is taken from the animation rate of the widget
"Asynchronous" sets async rasterization mode, where the constructor returns Promise immediately. By the default is False.

You can export AnimatedImage as GIF using file, ByteArray or a string as a container:

Export["anim.gif", AnimatedImage[...]]

ExportByteArray[AnimatedImage[...], "GIF"]

ExportString[AnimatedImage[...], {"Base64", "GIF"}]

Also Video object can be directly derived from AnimatedImage:

Video[AnimatedImage[...]]
