With this app you can create cool mp4 videos from multiple pictures.
You can select images from your gallery or from the camera.
You can add mp3 music as background sound of your video.
Choose among several video qualities (240p, 360p, 480p and 720p).
When selecting the quality, remember that the highest one (720p) will consume more resources and time to create the video, therefore you should avoid intensive work on your phone during the rendering of the video.

Enjoy it!
