1. A computer-implemented method, comprising:
receiving a list of multimedia files meeting one or more criteria; applying one or more priority processes to the list, the priority processes comprising time constraint filtering and bandwidth constraint filtering; and generating dynamically a playlist from the list based on the one or more priority processes, wherein the playlist comprises a single virtual multimedia file, the time constraint filtering is configured to allow multimedia files to be selected from the list of multimedia files having a playtime that is less than a defined time constraint, and files having a playtime less than the defined time constraint are given a priority based on playtime from a shortest playtime file to a longest playtime file, the shortest playtime file receiving a highest priority and the longest playtime file receiving a lowest priority; and creating a plurality of versions of a logical multimedia file depending on bandwidth requirements, hardware or device types on a client side, and a network carrier's regulations and requirements, wherein for each of the plurality of versions, a frame rate and resolution of the logical multimedia file are adjusted and header information of the logical multimedia file is modified correspondingly.
