I have severe scrolling lag on credits in FCP

Everytime you play the timeline, Final Cut Pro has to make many calculations to determine what pixels to display. Some areas may be more complex than others, and FCP may have difficulty playing in real time.

Rendering is doing these calculations ahead of time and saving the results. Instead of calculating everything, FCP uses the stored results (called render files) to know what to display in each frame of video.

I have ridiculous lag on my MacBook Pro and whenever I scroll i start to lag. This isn’t the first time and I tried to report it but it wouldn’t let me! I can’t even play Roblox on my MacBook. The MacBook is trash I’m not using it again until you fix the lag that’s just no

Please start a new thread and give specific details about your mac and the issue you are having.

There is no indication that your issue is related to the OP. It does not even seem to be related to Final Cut Pro.

Please be specific and, as LocaAlicia noted, we are just users like you trying to help.

We cannot help without clearly understanding what the problem is.

Does it lag if you render that section of the timeline?
