Abstract: 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.

Abstract: A method and system for capturing video and/or audio streams and for publishing consolidated video and/or consolidated audio streams. A capture profile specifying parameters for capturing the video stream and/or audio stream is selected from a list of predefined profiles as a function of data contained in the video and/or audio stream. A publish profile specifying parameters for publishing the video stream and/or audio stream is selected from a list of predefined profiles as a function of data contained in the consolidated video and/or consolidated audio stream. Moreover, the publish profile is selected to provide the best quality video and/or audio during playback, or to provide the best fir for a maximum file size designated by the user.
