FCP7 not recognizing video after replacing audio with ffmpeg

I work with audio and video that are recorded with separate devices. I use ffmpeg to replace the bad camera audio with a clean track without re-encoding anything so it's completely lossless.
ffmpeg -i INPUT.MOV -i INPUT.WAV -map 0:0 -map 1 -c copy OUTPUT.MOV
Once in awhile, I run into a batch of video that FCP7 won't recognize after replacing the audio. It drives me crazy because in this scenario, I have to manually sync the audio in Final Cut, which renders the waveforms totally wrong so I have to actually listen and adjust. Takes up a lot of extra time and if the audio is accidentally moved out of place, there won't be an offset count to catch my eye.

There is no system but GNU and Linux is one of its kernels.
