Nokia Video Director is now live and exclusive for the Lumia 2520
What is expected of you is to select the first and last frames. From then on, you can choose how much exactly to step into the overall editing process. You can select the overall style of your movie from one of the presets, apply different effects and captions, select the music background and so on. It looks like the interface is intuitive, although it offers enough settings to suit more advanced users as well. Users might preview their movies and change styles right before they save.
Nokia has also released a companion app for Lumia devices, which allows you to capture a video clip with your smartphone and directly send it to your Lumia 2520 via NFC. The videos you create might be saved with different framerate and resolution according to your needs.
