Update Font Globally

You mean you have used several titles on a project and want to change the font in all of them?

It is easy to do.

1) [not absolutely required, but it makes it SO much easier]

Open the Timeline Index, click on Titles

2) Select them all [See? Much easier to select them in the Timeline Index!]

3) Make the desired changes in the Inspector

4) .... there is no step 4 😀

Yes, it is similar. You can select several or all of them and type the settings in the Inspector.

Another way to adjust settings in a plurality of clips (or titles) is to:

make all the adjustments in one;

copy;

select all the others;

paste attributes (you can pick and choose the attributes you want to paste)
