gopchop | Fast, lossless cuts-only editor for MPEG2 video files | Mehr ...
gopchop cuts and merges MPEG2 video streams. gopchop uses a method to cut streams that does not require re-encoding, and therefore is fast and not prone to the artifacts and degradation of quality inherent in re-encoding. However, cuts are limited to I-frames or group-of-picture (GOP) boundaries. These frames occur frequently enough, and often times at scene transitions, so that gopchop's method is adequate for many applications. . The typical use is manually editing commercials out of recorded television programs. . Another application is splitting .VOB files from dual-layer DVD rips so that the content can be re-authored such that each half will fit on one single-layer DVD recordable.
