Full Production Studio note: this skill drives the toolkit in agamm/video-agent. Clone that repo and run your agent inside it for the scripts/paths below to work; the guidance itself is usable anywhere. Join two clips with a deliberate, visible transition. This is plain ffmpeg xfade — no CLI command wraps it (it's a one-liner; only unique-code operations get commands). Use the recipe below directly. Decide which tool first: Visible transition between two shots (wipe, dissolve, pixelize…) → this skill, xfade. A cut that feels abrupt but shouldn't have a visible effect → you want a split edit, not a transition: stagger the sound and picture with audiolead in the EDL. Reaching for a dissolve to soften a choppy dialogue cut is the classic wrong fix — see cutting-rhythm. Seamless join, no visible effect (hide a hard cut) → the existing splice command (uv run video-agent splice a.mp4 b.mp4 -o out.mp4) — a fixed 0.04s crossfade. Effect on the footage itself (smoke, recolor, restyle) → grok-video-edit skill. xfade overlaps the end of clip A with the start of clip B. The offset is where the transition begins in the combined timeline = durationofA − transitionduration. Total output duration
