    摘要： As may be implemented with one or more embodiments, a video stream is divided into a key frame and subsequent chunks of frames including a key frame and Delta (Dx) frames constructed from adjacent frames by dividing the frame into Motion Regions representing groups of pixels, determining a pixel group in an Earlier and later frame that is a best match for a pixel group in a Motion Region of a Current frame, and determining motion vectors for best matches for the Motion Regions and/or by intra-frame compression. A bitstream may be built such that as x increases, motion vector and other data relating to a combination of Dx frames is represented by data that is less than all the data in the combination of Dx frames and increases at a lower rate than the quantity of frames in Dx compared to the quantity of frames in Dx 1.

    摘要： A computer-implemented method/system of providing video clip playback, including: (i) receiving a video feed; (ii) converting the video feed into a compressed format structure; (iii) uploading the compressed format structure to a first server; (iv) receiving an electronic edit decision list defining how to manipulate the compressed format structure; (v) saving the electronic edit decision list to a server; (vi) receiving a request to provide to a user terminal a video clip playback corresponding to a video clip defined by the compressed format structure and the electronic edit decision list; (vii) sending to the user code executable to provide the video clip defined by the compressed format structure and the electronic edit decision list, and (viii) responding to requests from the code when executed, to provide content corresponding to the compressed format structure stored, in accordance with the electronic edit decision list, to provide the decision list video clip playback.
