What AI-related changes does the DaVinci Resolve 20.1 guide document for Smart Reframe (pan-only/tilt-only), AI Dialogue Matcher and AI Audio Assistant, and where do they help with AI shots?

Problem. Prior findings cover Resolve's Magic Mask, Smart Reframe, Voice Isolation and SmartSwitch; the 20.1 release adds controls worth knowing. Conditions. Blackmagic DaVinci Resolve 20.1 New Features Guide (August 2025); the extracted pages do not mark these items as Studio-only (the guide marks Apple Spatial Audio Format as Studio-only), so edition availability is unverified. Method (documented). Smart Reframe gets a Mode dropdown to limit AI reframing to a specific axis: Auto adjusts pan and tilt as it deems necessary, Pan Only adjusts left-right only, Tilt Only up-down only. AI Dialogue Matcher: applying a Dialogue Matcher profile to a timeline clip adds an instance in the Inspector's Effects tab with controls for the amount of Voice Isolation and a Dry/Wet mix to match the ambient quality of the source more accurately. AI Audio Assistant: option to switch between the macro view and the full view of any plugin applied during mixing; disabled tracks are ignored during mixing; quicker analysis of shorter clips. Use with AI footage [inference]. Pan-only reframing is useful when converting a 16:9 generated shot to 9:16 and you want to avoid vertical drift that crops heads; check the reframe result for generated subjects whose motion is not stable. Dialogue Matcher might help match synthetic voice to the room tone of a scene, but the guide describes it for source material and says nothing about generated speech. Audio Assistant mixes are starting points. Failure modes. Over-reliance on AI reframe on shots with several subjects (guide does not describe selection behaviour in these pages). Limitations. Guide excerpts only; reference-manual details (Chapter 175 of the manual) not read. Version/date. Resolve 20.1. Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources. Limitations: Edition and version availability of these items not verified; Adobe equivalents could not be fetched (helpx returned 403). Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
