For WeVideo's new HTML5 editor:
The new editor requires a browser that can handle the HTML5 technologies that our editor requires. The following are the currently supported browsers (with more to come soon)
On top of the browser requirement, your device must be able to support Hardware Accelerated WebGL. If you are getting an error message saying your device does not support it, please check your browser's GPU details page for more information. The best way to troubleshoot is to navigate to chrome://gpu in Chrome and read what it says under Problems. Sometimes if you have a display driver older than 2010, a simple driver update can resolve the issue.
For WeVideo's old Flash editor:

Videos created on WeVideo can be viewed on mobile devices and tablets.
The WeVideo editor does not work on your phone’s browser. To create and edit videos on your phone, download the WeVideo app from the Google Play Store for Android or the App Store for iPhone.
Due to the nature of cloud apps, WeVideo relies on a stable Internet connection. Please keep internet provider speeds in mind when uploading large or multiple assets at once. If you have multiple simultaneous users on the same network, it is recommended to have enough bandwidth to provide each user with at least 1 MegaByte/second upstream and downstream speeds to prevent a slow editing experience.
