Yes, you can.
Today it's possible to share videos directly from the iOS Nixplay mobile app to your Nixplay frame. Android is to follow in due course.
- Select 'Send photos' from your Nixplay app (available on iOS only for now)
- Record a video (or select a pre-recorded version from your camera roll)
- Choose which playlist (or friend) you'd like to send the video to
- Enjoy video on your Nixplay frame!
