There is an App called Pixaloop that allows the user to incorporate animation effects into an image. The resultant animation is exported as a video in mp4 format. One nice feature of the App is that it allows you to easily add clouds to the sky area of an image. The direction and speed that the clouds move across the frame can be varied. I've been utilizing this feature to create stereoscopic animations from still images, the animation being the movement of the clouds. I do this work on an Android tablet, but the App, which is free, is also available for use on the iPhone.
Here are the steps:
1) Import either the left or the right eye view of a stereo pair into the Pixaloop App.
2) Select the Sky submenu at the bottom of the screen
3) Select one of the three cloud animations that are available in the free version of the app.
4) By clicking on the selected cloud animation you can very any of three parameters: horizon, opacity and wind. I don't know what the horizon parameter does, but giving the wind speed a negative value will cause the clouds to move from right to left instead of from left to right as is the case for positive values.
5) Pressing the right arrow at the bottom right of the screen will let you preview the animation.
6) Pressing the Export symbol at the top right of the screen will take you to the export page. The Export symbol is a cup with an upward facing arrow sticking out of it.
7) the Export page has parameters to set the duration of the animation and also the video resolution, from 480 to 720. I've been producing animations of 12 seconds in length at a resolution of 720.
8) Press the export button and the animation will be saved to your gallery.
9) Repeat steps 1 to 8 for the stereo pair image for the other eye.
I then combine the two videos for parallel view 3D viewing using the "Video Merge" App, which is also available for free from the Android App store.
Below are links to some examples of the results:
