Proscenium: a framework for spatio-temporal video editing
We present an approach to video editing where movie sequences are treated as spatio-temporal volumes that can be sheered and warped under user control. This simple capability enables new video editing operations that support complex postproduction modifications, such as object removal and/or changes in camera motion. Our methods do not rely on complicated and error-prone image analysis or computer vision methods. Moreover, they facilitate an editing approach to video that is similar to standard image-editing tasks. Central to our system is a movie representation framework called Proscenium that supports efficient queries and operations on spatio-temporal volumes while maintaining the original source content. We have adopted a graph-based lazy-evaluation model in order to support interactive visualizations, complex data modifications, and efficient processing of large spatio-temporal volumes.
