Please tell me a simple way to make the text+subtitle flash for a moment and then display it.
I think there are several ways, including creating in Fusion.
However, even without using Fusion, you can easily create it with only the functions of the edit page.
It is possible by creating a white "text+" of the same size as the "text+" to be displayed after lighting, and expressing them so that the color gradually changes with cross dissolve.
I made a video explaining how to make it easily, so please check it out.
