FINAL CUT audio syncing I make videos about drums and music. I record audio separately to video.
when I align the audio with the video after the fact, I always feel final cut never gives me enough resolution in terms of aligning the two media.
Also, just the visual of the waveform doesn't give me enough information for alignment (IMO).
example of a video I produced where I feel the visuals are minutely out of sync with the audio: 
                
            
Is there a function to sync audio to a clip automatically (and with 100% accuracy)?
can i raise the resolution of the timeline in final cut? if not, what other options are there for me?
record the audio separately AND on your camera.  Then in the editor, align the 2 AUDIO waveforms.  Play them back both together.  If you hear an echo then they are not exactly aligned.  After you have them aligned, then turn off the camrea audio and keep the audio you want.  Mark
