# gopchop(1)

Fast, lossless cuts-only editor for MPEG2 video files

## NAME

gopchop - Fast, lossless cuts-only editor for MPEG2 video files

## SYNOPSIS

**gopchop** \[ *options* \] \[ *file* \]

## DESCRIPTION

**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.

## OPTIONS

- **-h, --help**

  Help.

- **-p, --pipe** *CMD*

  Use external command for output. Recommended:  'mplayer -nocache -novm -'

- **-v, --vo** *DRIVER*

  Choose internal output driver.  Use 'help' as *DRIVER* for a list.

- **-s, --states**

  Show libmpeg2 decoding states during display.  Used mostly for debugging.

- **-V, --version**

  Display which version of GOPchop is installed.
