description: "Assemble an AI music video — trim each H3 part to its exact length, join at 1344×768 24 fps, lay the original track (the generated audio is discarded), faststart for players; one final upscale (Magnific Topaz Starlight Precise 2.6, Starlight Fast 3 only in the Topaz Video app). Part of the musicvideo reference set."

# musicvideo-edit · join, sound, upscale

1. **Trim and join** (one ffmpeg, `-threads 2`): every part `trim=0:<part length>`, `scale=1344:768,fps=24`, `concat`; the person's original `{track}` as the only audio; `-movflags +faststart` (without it some viewers will not open the file).
2. **Check**: a frame from the middle of every planned shot in one sheet; a scene-change count (`scdet`), the cut times against the plan.
3. **Upscale once** — `upscale-video-final`: Magnific `video_upscale`, `mode=topaz`, `enhancementModel=starlightPrecise26`, `targetResolution=1920`, `targetFps=24`, `frameInterpolation=apollo`, `focus=0`, `sharpen=0` — upscale only the finished clip; 1344 × 768 → **1918 × 1096** (not exactly 1080); the result is silent — lay the track back with `-c:v copy`. Freckles, hair, lace and embroidery come out sharp, the face stays the same. Starlight Fast 3 exists only in the Topaz Video app (not in the fal or Magnific APIs).

## Example run (reference only — never reuse its files, prompts, faces or frames for a person)
