Follow these steps to add a title card to your OpenShot Project:
From the menu bar, select Title -> Title.
In the Titles windows, select a style of title. Give the title card a File Name, and then edit the text as needed. You can also edit the Font and it's color. If you change the Background Color, it will prevent layering. Click Save.
The title card should now appear in the Project Files section. You can now drag the title card wo where you would like it to appear.
If you haven't changed the background color of the title card, you can place a still image or a video on a lower track, and it will appear with the title card.
Any title card can be used as an overlay for video. Create a title card as before, and then drag it from the Project File to a track over where you would like it to appear.
To make a overlay or title card fade, right click on it and select Fade. You can then choose from a number of options for fading.
If you have also installed Inkspace, you can click on the Use Advance Editor for any title card to customize it. You can add or remove elements, move text, and change fonts.
