摘要: Methods and systems enable content authors to achieve frame-accurate editing and, in at least some embodiments, reduce the amount of content that needs to be decompressed in order to operate on the frames. Some embodiments ensure that bit rate integrity is preserved so that bit rate conditions associated with streaming environments are preserved. Various embodiments intelligently determine which content portions should be decompressed, processed, and recompressed and which content portions should not be decompressed.

摘要: Systems and methods for processing input media in a computing device are described. In one aspect, a reconstructed frame is cached according to a set of criteria. A request to scrub to a predictive frame of input media is received. Responsive to receiving the request, the predictive frame is decoded starting with the reconstructed frame.

摘要: To represent the motion of a pixel between successive image frames, this method utilizes the motion information for the transformation block containing the pixel, as well as the motion information for adjacent transformation blocks whenever the adjacent transformation blocks are associated with the same object with which the selected pixel is associated. As a result, transformation errors arising from transformation block discontinuities are decreased and the accuracy and integrity of motion representations of pixels within an object are maintained. Preferably, the motion representations for the transformation blocks are multi-dimensional or affine transformations that are capable of representing complex motions that include any or all of translation, rotation, magnification, and shear.
