"Group of pictures" is still a technical term that only makes sense
to those familiar with MPEG video streams.

How about:

  GOPchop cuts and merges MPEG-2 system streams.  GOPchop uses
  a method to cut streams that does not require reeocoding (so
  it is fast), but cuts are limited to certain frames in the
  video, known as I-frames or group-of-picture boundaries.  These
  frames typically occur multiple times per second, so the method
  is adequate for many applications where a full-featured video
  editor is not needed.
