I have two different videos. Now here's the thing, they have the same lengths, and they are related to each other. Is there a way that I can play these videos on at the same time using VLC and also have a unified seek bar, so that the times are the same for both, since one video is dependent on the other.

Does it HAVE to be in VLC? If not, please edit your post and remove that requirement (and tag.) – Ƭᴇcʜιᴇ007 Sep 2 '13 at 19:17
Okay, it does not have to be. – Games Brainiac Sep 3 '13 at 2:10

I haven't seen any player that could do that, but you could merge the two video files together to achieve what you want. See questions like

I have recently solved it with mplayer and you can see the solution on superuser here: master-slave with mplayer

You can use AutoHotKey to achieve something similar though not perfect. I posted my answer to a question similar to yours here

This would be more appropriate as a comment. You're really providing a hint for where to find an answer rather than an answer. – fixer1234 Oct 10 '15 at 0:47

If anyone is still interested in this the current version of VLC is able to do this very well without any kind of scripting or add-on. To accomplish this simply open VLC and select Media>Open Multiple Files. Inside the multiple file windows select add to add the first file. After this click on the, "Show more options," checkbox followed by the, "Play another media synchronously," checkbox at the bottom of the window. Select browse next to, "Extra media," to add the second file. Hit play and the two media files will play simultaneously with a single control window.

If a multiple question have identical answers, they should be flagged as duplicates, submitting the same identical answer multiple times is odd behavior. – Ramhound Jan 22 at 16:32
