I recently got Keynote 6.0 and I'm having trouble animating a gif in it. Using Insert > Choose... easily adds the gif to the slide, but without animation. I have searched and found other sources (example) which all seem to point to using the "Quicktime Inspector" to work with the animation of a gif. Unfortunately, the Quicktime Inspector no longer seems to exist in version 6.0 and I can't seem to find the solution otherwise. Any suggestions? Thank you much!
The new Keynote (v6) doesn't import GIFs in like it used to, which is disappointing.
However, if you open an old Keynote presentation (Keynote '09), Keynote v6 will ask you if you want to update and/or optimize it for iOS devices. If you optimize, it will render the animated GIF into .m4v. Once that is done, if the Format inspection, you will have a "Movie" tab.
The down side is that you MUST have Keynote '09. I tried to export an animated GIF created in Keynote v6 as Keynote '09. It did not maintain the animated GIF correctly, so when I reopened it, I did not get the "Optimize" option
if you want a GIF to repeat itself, as beroe correctly pointed out, save the .gif to some folder, change it's file extension (make sure to show the real extension and not hide it (cmd+'i' is the canonical version, change it there if you're unsure)) to .mov and then drag it to keynote 6. Optimize for iOS and now select "endless" in the "format->Film" section under "repeat" (I don't know the correct translations as I use a german keynote).
I was unable to import an animated gif into Keynote 6.2.2, so I converted it to mp4 via https://cloudconvert.com/anything-to-mp4 (I googled "convert animated gif to mp4"), and then I was able to just drag and drop the mp4 into Keynote.
