No, I didn't mean that either. I was thinking more that to get a continuous sound track you have to leave the camera recording all the time. One can then replace parts of the action shots with cutaway shots, but letting the sound track from the action shot run on. But a problem comes if you want to cut from one action shot to another, whilst preserving an apparently continuous sound track AND still having the music in sync with the action. You seemed to achieve this, for example in the opening sequence where I counted seven cuts in the picture but only one possible discontinuity in the sound.
But it may be that you were aided by the music having a fast rhythm and repetitive melody.
I just wondered if this was a big consideration in the editing, or if there were any tricks you could share.
