i3DMovieMaker

This is a 3D video/still image editing application for iPhone/iPad.

It can convert and display 3D video (left and right separately, half-width SBS, full-width SBS) and 3D still images (left and right separately, SBS) to various stereo formats (left and right separately, half-width SBS, full-width SBS, LR/RL, various anaglyphs).
You can adjust the position of the left and right images, cropping, and edit the cut of the beginning and end of the video.

You can easily edit 3D videos shot with i3DMovieCam, 3D cameras, and 3D movie cameras.

In-app purchase is required to use the video saving function, but all other functions are free of charge.
