Because Animoto is entirely web-based, it can work on both Mac and PCs. If you're having trouble creating a video, make sure you're using a compatible (and up-to-date) web browser.
Animoto currently supports the following browsers:
While some features of Animoto may function in other browsers not listed above, we can't guarantee future compatibility or provide support for older versions or other browsers.
Lastly, videos on animoto.com should be viewable on iOS devices (iPhone/iPad/iPod). Note, however, that you can only create videos on those devices using the Animoto iPhone/iPad app.
