Question / Help Can I make a grid of video files?

[VicDiesel]

Say I have 4 video files. I've made a scene that has 4 sources, all Media Source, corresponding to these 4 files, all nicely resized to make a 2x2 grid.
Now how do I render this scene to a video file, with all 4 videos starting simultaneously?

Enable the "Restart playback when source becomes active" option in the Media Sources, then switch to another (black) scene and back.

Thanks. That worked. I guess now I need a faster drive to keep the videos in sync.
How about if I have two scenes, one with only 2 of the videos, one with 4, and I transition between the two? How do I start all 4 videos? I'll experiment.....
