Just yesterday, Microsoft detailed some changes coming to Cinemagraph's backend through OneDrive and today, that updated app is now available. Labeled as Lumia Cinemagraph Beta, the app can be downloaded through the Store though currently the link is not searchable (so you need the app's direct link, found below).
The biggest changes in this version affect how you share Cinemagraphs detailed in the Beta release notes.
"Now cinemagraphs are shared directly as repeating video clips through the normal sharing steps. As a result, there's no longer need for a separate upload step or user account and all the normal sharing destinations supported by Windows Phone are available."
"The newly shared cinemagraphs will be available in the Shared Cinemagraphs folder on your device. Note that there's no longer a Shared view for online cinemagraphs in the application. If you need to access your previously shared cinemgraphs on our server, please use the Lumia Cinemagraph (non-beta) application still available in the Store for that."
"Please note that Lumia Cinemagraph Beta is only available in English."
Certainly this makes taking and sharing Cinemagraphs much easier without the Nokia account.
For those who have never used Cinemagraph, the app creates an animated GIF like file using your Lumia's camera. They are perfect for capturing moments where part of the image is static, and something else is moving, creating a mini-looping video file.
Grab the beta version of Cinemagraph and remember to leave them feedback to help improve the app for its final release.
