iMovie heating up MacBook and using a lot of RAM, despite being new
I recently purchased and started using a new 14-inch MacBook Pro. Recently, when I exported a movie file from the app, the Mac heated up a lot, and seemed to heat up more than when I exported movies and videos from iMovie on my old Mac from 2016/2017. The export on the new Mac was also slow and took up 13GB of the 16GB of RAM, and I feel like it was connected to the heat issue. Is there something I can do, download, etc. to mitigate this issue on the Mac? What should I do?
MacBook Pro 15″, macOS 10.15
