I've been trying to use a custom
.TTF font on OSX to watermark videos edited in iMovie. But there doesn't seem to be any option at all.
Does anyone know how to achieve this?
First: Install the font:
Second: Change font in iMovie:
If you're in iMovie and you have a textbox, select the text you want its font to change and hit Command + T. The font selection popup opens and you should be able to select your installed font.
