Open the Static folder of the Text tab in the editor to find the End credits title.
Step 2) Open the clip editor
Add the End credits title to your timeline and double-click the title to open the clip editor so that you can input your own text.
Step 3) Go to the Animation tab
Once you've modified the text properties, navigate to the Animation tab.
Step 4) Set the starting point
Change the Y coordinate to 1050 or manually drag the frame to reposition the text clip and set the starting point underneath the visible frame.
Step 5) Set the ending point
Change the Y coordinate to -850 or manually drag the frame to reposition the text clip and set the ending point above the visible frame.
