Package details
openSUSE:

xjadeo is a very simple video player that gets sync from jack.
When a sequencer like Muse or Rosegarden acts as a timebase master, xjadeo will display the video frame in sync with the sequencer transport.
This means that you can visually synchronize an audio event with a certain frame in the movie, which comes quite handy when you want to create a soundtrack for a video clip.
