FCP renders the same content over and over. Why?

I have a new mac studio and was hoping for better performance compared to my old machine, but FCP is constantly rendering. Yes, I know you can turn background render off, but that's not the issue. Why can't it render an edited sequence once, and just use that rendered file from then on unless I re-edit the sequence? I'll do a project, and it will fully render. If I come back the next day, it renders it all over again. Over time my rendered files folder in that project will get huge, 600GB or more, and I just have to manually delete it because my hard drive is full. Then I get to render it yet again. What gives?

This is an old problem that’s usually caused by some project content. I don’t know if a solution was ever found. You might try FCP.co. There are users who have more experience with this problem. I’d just switch off background rendering.

The problem is I sometimes need to see the rendered content to judge if the edit is good or if it needs tweaking. Real time playback is often choppy and poor resolution, so I'm constantly having to re-render the project to edit it. I saw many old posts on this issue, but no new ones, so I must be in the minority having this problem in 2022. I will try FCP.co as well. Thanks.

You might try working with proxy files to improve playback performance.
