Spinning wheel in FCPX is killing me.
I'm editing several 2 hours long screen recordings with very basic transitions from a plugin, but the entire software keeps hanging on the spinning wheel every 30 mins or so. It seems like it happens when I put a JPEG file on the MPEG4 footage.
I've tried transcoding the footages to proxies, tried force quitting FCPX but FCPX will not start after I force quit it. Have reset my PRAM using terminal sudo -c too, after upgrading my iMac to Catalina from Mojave.
Please help!
