Subtitler:Only the first 25 minutes are rendered in Final Cut Pro

I have imported two hours of subtitles into a Final Cut Pro project. Only the first 25 minutes are rendered, and the other part requires a render. Why do I need to render?

Depending on your hardware configuration, you may or may not need to render your titles. But even in a realtime system, the number of titles can go beyond the limit of Final Cut Pro. If you have a lot of titles, some may not want to play. Increase cache or render some of the titles.

1. Go to the menu Final Cut Pro:System Settings....
2. Open the Memory & Cache tab.
3. The Still Chache slider defines the amount of memory you have for subtitles. FCP uses about 1-1.2 MB per subtitle on standard definition.
