I've recorded an event with 2 camera at the same time (2 point of view).

Now I would like to make a video and switch the view from one camera to the other and viceversa but without cutting the 2 recorded video because I don't want to lose the sync.

For example:

Output  - 11221122

Track 1 - =======

Track 2 - =======

The "Output" row show the number of current track showed.

Is this possibile?

Yes, it is possible. You can achieve it by adding a transition between the 2 tracks, for example a Wipe transition and set parameters so that the image of the upper track is off screen.
