Yes having the option to use video would be fantastic. Even better if you could drop a YouTube link and have it play.

HURRRAAA, can't wait for the next update!!

I'm so disappointed that I can't do it now......

More importantly, bring in custom animations for prototyping. This would be clutch for handing stuff off to developers so they see the whole picture and theres literally nothing missing for them to code up an app and basically make it look just like these prototypes, having a guide.

When I said I would like to see MOtion Design like Afte Effects it was more like importing a motion design already done in Ae.

I don't know if live videos is overkill, but I would like to see motion design like in After Effects in Xd.

This is an important feature—even if it might not be used heavily. It can be in V1.xxx that maybe you offer limited support for animated images: say GIF—with plans to enhance and increase support.

Why this is important: (current project as an example) we are testing a welcome screen and trying to help users understand how to use a feature. *We have hypothesized that with a simple animation shown to the user—one that leads them to do an action, in this case turn on an extension (in an action sheet on iOS), so that they can use the extension in other applications.

In our research we have found that people don't realize they have to turn the extension on and don't even realize that when they do enable it where the extension is located. To test our animation and user interaction with the action sheet we needed to build a prototype that can handle the animation, basic interactions, as well as simulate native iOS UI.

Both JustinMind and Axure allow for Flash (but we can't display that on an actual iOS device) or Youtube support or animated Gif. This was helpful. But, it took awhile and some tinkering to figure out just which one worked best—GIF.

I am more concerned with being able to tie a animated sequence (gif, mov, etc.) to user interaction and test these as we move more and more into a flexible personal device direction.

Completely disagree that it's overkill. Communicating to senior stakeholders what's a movie and what's an image is necessary for buy-in and dev scoping. Placeholder images or animated gifs just don't cut it. Would also want the ability to auto play on page load (in addition to tap to play).

This would be an impressive feature to present to clients, in the process of bringing their concepts to life

Import animated gif

I think it's overkill. Live Videos are not that much important when prototyping.
