Is there a way to change the processor priority in FCPX?

I have a project where I need to share to master file 10 different videos. I have some 3d text and Denoise in all the videos. Both are so processor intensive that they bring my processor to a grinding halt. After the first one begins exporting my computer is so slow that I cant export the rest. Then I wait a few hours for the file to render.

Is there a way I could lower the processor priority of the export process so FCPX will still be normal speed? Another way to help would be if I could put everything I want to share to master file in a batch list, but I don't see a way to do this.

I don't think you can change how the export goes, but you do not have to wait for each one to finish.
FCP X will queue them for you, so you select one project, export, then another, export, and so on, and go to bed, or do something else, and they will all get exported. Even faster if you add a keyboard shortcut. Even if FCP X is slow while exporting, you can still do this.

Yep, text and 3D text can eat up time exporting. What is the duration of each video, what codec are you exporting to? Just curious.

I batch export daily (at least I call it that). I send one episode out for export, then touch up the next timeline and export, touch up the :30 spots and export each. Don't have to wait for one to finish before doing the others.

They are 10 minutes long and I am exporting to Prores 4k. Once my computer starts exporting the first video FCPX becomes so slow that I cant export the second one. The 3d text is making it slow and also the Denoise filter. My computer is a 2014 macbook 8 gigs of ram. How fast is your computer. Maybe I need a faster computer to be able to edit while exporting.

I don't know what time frame you're working to, but I don't think your computer can properly handle what you'd like to do. I'd Send to Compressor and build a batch list of projects there and set it off to process overnight.

What version of FCPX and macOS are you running? Normally FCPX will sense user input during a background operation and temporarily pause that to give better response. This can be seen if the background tasks pane is up (click on the pie chart in the upper left). Any user input will result in a yellow message saying "paused". When you stop making user input it will resume.

I don't remember if it has always done this or whether the background tasks pane must be up, but current versions behave that way.

It is normal for 3D text and especially video noise reduction to be very CPU-intensive and take a long time to render & export.

By 2014 Macbook, do you mean Macbook Pro or MacBook Air?

What Tom said is your best solution -- Compressor was designed for things like this. There are lots of tutorials on using this, especially from MacBreak Studio.
