Simple split-sceen video in Photoshop

[Lagom Bra]

I have to compose a HD 1920 x 1080 video where two videos appear side by side (split-screen). I have recorded both videos so the relevant things would show on either half after composing. How can that be done with Photoshop's basic video editing tools?

Apply a layer mask to the visdeo layer.

As per @Mylenium ’s advice a Layer Mask should suffice. 

If you need further information please post a screenshot with the pertinent Panels (Toolbar, Layers, Options Bar, …) visible.

Open the first video.

Click onb the drop down and chose New Video Group

Select the Video Group 2 > use the drop down > and Add Media

You now have two videos running at the same time with the upper video hiding the lower video

In the layers panel you will have a group for each video group in the timeline

Select the upper group and give it a layer mask (my green highlight)

Fill whatever part of video group 2 you want to hide with black.

Job done

BTW  The clip on the right is the tree I had just parked my drone in, moments after the video on the left. 😞
