Here's a look at one of the cool video editing technologies Microsoft is working on.
We introduce a new representation for video which facilitates a number of common editing tasks. The representation has some of the power of a full reconstruction of 3D surface models from video, but is designed to be easy to recover from a priori unseen and uncalibrated footage. By modelling the image-formation process as a 2D-to-2D transformation from an object’s texture map to the image, modulated by an object-space occlusion mask, we can recover a representation which we term the “unwrap mosaic”. Many editing operations can be performed on the unwrap mosaic, and then re-composited into the original sequence, for example resizing objects, repainting textures, copying/cutting/pasting objects, and attaching effects layers to deforming objects.
