One suprising thing that seems to work with video/footage (a shot) once you've watched it a few hundred times and can't really 'see' it naturally any more, is to 'flip' it (horizontal mirror (or negation)) the result is usually surprising at least and can reveal things you couldn't see before! Or, if flipping has run out of juice too, even flopping (vertical mirror or negation, yes the shot is upside-down now, so not as helpful as flipping) but either/or and their combinations can definitely provide some extremely useful new perspective on the visual content one is trying to produce (VFX day job as Pipeline TD now, FX artist previously and this idea helped me numerous times!)
