Dan Kieft (2026-09-29, Higgsfield-sponsored) uses a desktop chat agent ("GPT Astra", as he names it) with MCPs for Higgsfield, DaVinci Resolve (paid version) and Blender, plus computer-use control of Premiere Pro/After Effects: (1) trim dead space from transcription, insert editor-note adjustment layers and mark candidate B-cam/C-cam spots - works but slow (about 14 minutes for some trims via screen control; the Resolve MCP is much faster) and needs monitoring; local desktop app needed for large camera files (cloud upload limit 512 MB); (2) synthetic B/C-cam angles: give a photo of the room and the A-cam clip, generate side angles with Seedance 2.5 (plausible shadows and light placement; small set-dressing errors); (3) B-roll of himself from three phone photos turned into a character sheet; (4) motion graphics: agent-built After Effects projects from style references (project file handed to a human editor) and generated pixel-art avatar inserts; (5) VFX: mark exact frame numbers (107/279/567) for events and have the LLM write frame-timed prompts with element references; (6) grading: apply the official Sony S-Log3 to Rec.709 LUT via the agent or grade in Resolve via MCP; (7) sound: have the agent analyze a clip frame by frame and write a sound-design prompt, generate with Seedance at low settings, then swap only the new audio back onto the original high-quality video. He insists editors are not replaced and recommends approving agent actions to avoid runaway credit/token spend.

Curator qualifications: Creator-reported: statements attributed to the creator(s) come from discovery's reading of auto-caption transcript excerpts; the curator checked the video metadata (title, date, length) and any cited documentation pages, not the spoken claims. Nothing was tested; promotional or sponsored framing applies where stated. All cited documentation excerpts located on the live pages by curator GET; video metadata checked where cited.

Limitations: Creator statements were read by discovery from auto-captions (ASR); not re-verified by the curator. Sponsored; "GPT Astra" naming unverified; generated "B-cam" angles depict events not filmed (disclosure considerations for documentary/news use).

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
