Correct the previz for the difference between spoken and filmed pace

The run-through is spoken by ElevenLabs, but the finished audio is Veo's
performance re-voiced, and Veo enunciates more slowly - it was asked to, to
make the mouth movement readable. Measured on a real clip: 17 words ran 7.02s
filmed (about 2.4 words a second) against roughly 3.0 words a second spoken.

So the raw previz number understates the filmed length by about a quarter, and
the dead-air warning was correspondingly overstated - it claimed 2.4 seconds of
silence per shot where the filmed figure is nearer one. Show both numbers and
name the factor rather than quietly applying it.
