Video recorded on iPhone 14 Pro doesn't sync with WAV file

I created a WAV file in Logic Pro and then used an iPhone 14 Pro to record a video of me playing an instrument. When I brought the video and audio into Final Cut Pro, I couldn't sync the files. It started out fine, but about halfway through, the audio started to lag noticeably behind the video. Is there anything I can do to fix this, or do I just need to use a regular video camera to record my footage? (I've done it this way before many times with a Canon Rebel and it's been fine, but my iPhone 14 Pro looks so good that I really wanted to record the video using that device instead). Thanks!

All audio files must be 48kHz sample rate, 16-bit data rate. The sample rate is VITAL! If they're not both 48kHz they'll drift out of sync.

And yes, my iPhone 14 Pro Max has amazing quality video. I use it more than my DSLR cameras now.

Yes, good point, Tom. I often forget because I very rarely mix iPhone with DSLR clips in sync or multi cams. So you'd want to set your other cameras, if mixing with iPhone footage, to 44.1. And when I do, I'm using audio from my DR-10L exclusively.

So why Apple insists on this 44.1 non-standard audio is beyond my sense of logic. There's no technical need for it.
