Windows 7 – How to play multiple videos side-by-side synchronized?

I’ve got 3 videos, all 3 have the same time, same amount of frames, and they only differ in terms of encoding quality.

Now I need them to run side-by-side in synchronized fashion for evaluation purposes. Meaning when I press “play” BOTH! videos should start. Analogically for stop, forward, backward.

Anyone know any player capable of doing that? By that I mean playing more than 1 video side-by-side…

Platform: Win7

Solution:

VLC on Windows (1.1.10 or later):

  • Tools → Preferences
  • Show Settings → All
  • Click Advanced (Click Playlist for VLC 2.1.5)
  • Uncheck “Allow only one running instance”
  • Uncheck “Use only one instance when started from file manager”

VLC on OS X does not provide the same set of options. You can however run multiple instances from the Terminal with open -a VLC.
