How can I add animated pictures or objects? beside the "path" there are some animated objects that move on their own, How can I do that? like the ones on this presentation http://prezi.com/ko8nf7vfi_wk/prezpad...
you can use flash objects (SWF files) to create animation and there are lots of software types available to do this (Adobe Flash being the the most prominent I would have thought) or you can make a .gif animation (clipart - you can find loads on the web) and convert it to a swf using a image converter - just google - I use Any video Converter and Format Factory.
I agree with all the comments I'm finding here and elsewhere. With the incredible proliferation of animated gifs on the web today, it seems incredible that Prezi is not supporting this format, and that you seem to have no plans to.
I am interested as well to put animation inside a given step of a Prezi.
Actually I use to create SWF with Adobe Flash Professional, and in general it works as needed.
I'd like to check with you if you have encountered the following limits, and if you could overcome them:
Not all the SWF files are accepted by prezi, for example if I do some more specific animation with Action Script 3 (language adopted by Adobe Flash), like for example to have the effect of flipping the pages of a book, then the resulting SWF is not accepted by prezi (literally it says "Action Script is not supported").
Even for simple SWF files that are accepted by prezi, if they have themselves any interactivity, like reacting to some mouse click, it may happen that the prezi cannot distinguish when the click is intended for the SWF or for the prezi.
Last but mos important: any idea of what format I can adopt, to have an animated content displayed in prezi from an iPad?
yes, you are right about flash and action script - if the code is detected you will receive a 2700 error - Action Script is not supported. You may be able to get some SWF files to load (and through Prezi Desktop) but generally it will not work with any interaction. Some mouse overs and clicking may still work...but this is not guaranteed I'm afraid.
Unfortunately the iPad does not support flash, and therefore there is no animation (other than the Prezi fade in).
