What should I do if the video copy made by the fast film is too long to fit?

You can cut a little.

Drag the bottom-up scrolling subtitle template in the subtitle library to the corresponding position of the video on the subtitle track, and double-click the browse window.

Delete the subtitles in the rolling subtitle template and copy your personnel statistics (Ctrl+V). Personnel statistics are edited in word, arranged in rows, and the left and right cannot exceed the box in the browsing window, and then the font, size, color and other attributes of the text are further adjusted.
