For a "workaround" transition, you can use stock footage with alpha channels or specific sound effects to enhance existing built-in transitions like the Alpha Wipe

Some fancy free transitions require 3rd party plugins like or ProDAD VitaScene . If you download a transition that says "Requires NewBlue," it won't work without that paid software installed.

These are 100% free, always work, and don’t risk your system’s security.
