Fast Graphical Editor for MPEG2 Video Files
GOPchop is an open source tool for losslessly cutting and merging hardware-encoded MPEG2 video files. It limits cuts to I-frames or group-of-picture (GOP) boundaries, thereby preventing artifacts and degradation of quality by not needing to re-encode. GOP boundaries occur frequently enough (especially at scene boundaries), that GOPchop's method is quite suitable for many applications. It tends to be most handy for people working with streams created by hardware encoders.
GOPchop is useful for:
- Trimming recordings to desired start/end times.
- Extracting short clips from longer recordings.
- Editing commercials out of recorded TV programs.
- Splitting .VOB files from dual-layer DVD rips so the content can be put on each side of a single-layer DVD-R.
March 2, 2009 - Various fixes since 1.1.7 added, especially a fix for the annoying Xv crasher. The entire CVS tree has been migrated to Subversion too.
May 2, 2005 - GOPchop is nearing the 1.2.0 stable release. This version even includes some experimental MPEG1 support from Brent Baccala. Several small fixes were added since the 1.1.6 release's changes to preferences handling. Download it and give it a spin!
Apr 30, 2005 - The long overdue development cycle release of GOPchop is finally here! This version improves the UI, adds additional parsing support for certain kinds of stream elements, fixes several compilation bugs, adds options for system header injection/removal, and uses a more hardy picture display system, which will always display the final picture of a GOP. The goal is to close in on a 1.2.0 stable release within the next week so that several of the patch bundles recently sent to the gopchop-devel mailing list can get some development attention.
Apr 29, 2005 - As part of the preparations for the next 1.1.4 release, we've set up a new website. Hope ya like it. The PHP is mercilessly stolen from the Inkscape project. ;-) Huge thanks go to Bryce Harrington.
