Hello again. I looked more into the settings on the video/audio within FCP, as well as my camera, and found the problem was indeed the 32 kHz that I’d recorded the tape as.
I changed it to 32 kHz in the audio/video in FCP, and then also changed it to 16 bit on my camera so it’ll be good to go on future shoots.
It is capturing the footage fine now that it was changed in FCP. I’m so relieved to have that settled now. Thanks for the tip, Steven, and for your help as well, Rafael!
