Lower Denoise Fixed H3 Video Glitch: 0.97 Beats 0.98 in A/B Test

The author habitually sets Denoise near 1.00 to keep H3 faithful to prompts, but an A/B test (all other settings identical) showed 0.98 produced a thumb clipping through a book, while 0.97 rendered the action correctly.

Takeaway: when the model glitches, lowering Denoise and giving it more freedom can work better than tightening control with a higher value — a counterintuitive practical tip for video generation workflows.
