No, it's actually a real concept in music theory. I invite you to read about it. Other, more in-depth treatments of the subject can be found in music theory textbooks.Eva-Fan wrote: Melodic motion? LOL? Seriously, did you just come up with that to try and proove a point or something?
Here's an example: say you have an ascending harp line. There's many ways to map that to something visual; the first way which comes to (my) mind is to lift the camera up through a busy, enclosed space.
That by itself doesn't make for a coherent story, but it's just a unit; therefore, you take units and string them together to make a coherent whole.
I don't think it's necessary to establish any sort of really solid beat-sync pattern for that to be the primary method of synchronizing the audio and video.
Indeed, there was a video posted on CGTalk not too long ago that I think nicely illustrates the idea. The creator of the video does synchronize some actions to beats, starts of measures, etc. -- I won't say he doesn't -- but he does much more than that, and kinda shoves the beat into the background for most of the video. I don't think the bulk of what he does can easily be classified as "beat sync"; it enhances the sync between audio and video by mimicing the motion of the melody (and, for that matter, ornamentation as well.)

And that is the point: it doesn't really fit into the strict definition of "beat sync", and yet it does contribute to sync. It's about finding a way to map motion from one domain to another.Motion being matched to a melody is most definitely NOT beat sync at all.
