The open DAW documentation gives concrete crossfade and grid facts: Ardour's constant-power crossfade (-3 dB each at the midpoint) is the splice for uncorrelated material, linear (-6 dB each) for highly-correlated signals, symmetric for editing two entire music works together, default fades are short de-clickers; the musical grid (bar, beat divisions) scales with tempo while timecode grids do not. Music editors add that cues are repeatedly lengthened, shortened or reworked as picture changes. No inspected primary source states a rule that cuts should land at phrase boundaries or downbeats; that rule appears only as a synthesis (cut on bar lines of a tempo-mapped grid and crossfade across the join) and in secondary search results not fetched.
