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.
