Video Collage (Resolve FX Transform) is a Resolve FX that you apply on the Cut or  Edit Page.

It allows you to quickly create grid-based layouts and split-screens effects.

We look at using the Background & Tile options, as well as the new Render in Place.

This allows you to render all effects that are applied to a single clip on

the Edit page. You can also share this file with another editor, as it saves the file as a rendered movie.
