You can customize DaVinci Resolve templates by editing the media placeholders, titles, and logos. To edit the media placeholders, you’ll need to import your own media files into the Media Pool.
To edit the titles, go to the Titles folder, double-click on the title you want to change, and then select the title on the timeline and go to Inspector on the right side of the screen. There you can change the text, size, font, and more.
