Audio not matching video when dropped into timeline
Using Intel iMac 27" (Sonoma 14.3.1) with FCPC (10.7.1). All of a sudden, whenever I drop a video into the timeline the video and audio do not match up. The audio lags significantly, about a second. When I import it into FCPX and click on the imported video, everything is fine. The lag comes when I drop it into the magnetic timeline.
Anyone have a suggestion on how to fix this???
iMac 21.5″, macOS 10.12
