Region Callout
他を暗くし、その領域を光らせ、コールアウトに名付けさせます。
地図、図表、画像のひとつの領域へ注意をズームします。その領域がハイライトされ、他が暗くなり、コールアウトの線が詳細を記したラベルカードへと伸びます。

Region Callout
When to use
- You are presenting a map, diagram, chart, screenshot, or photo and one region carries the point (a neighborhood, a chart spike, a UI element, a defect)
- Saying "in the top right" loses half the audience; you want the region itself to light up and name itself
- The clip is a 10–25 second beat inside a longer explainer, a lesson, a report video, or a product walkthrough
- The base image is busy — without a callout the viewer scans everywhere and finds the point late or never
- You need to chain callouts: first region A, then region B, building an argument across one image
Workflow
- Choose the region (input: base image → output: one bounded region)
Draw the region as a simple shape: rectangle, ellipse, or a freehand-style rounded outline following the region's natural boundary. One region per callout — if two regions compete, that is two callouts in sequence. The region must be big enough to see at phone size (at least ~8% of frame width); if it is smaller, you need a zoom step (step 4), not a bigger outline. Name the region in 1–5 words; write its one-line detail (≤12 words) now, not during animation. - Dim the rest (input: base image + region → output: focus composition)
Drop the whole base image to 35–50% brightness/saturation except the region, which stays full-strength — or overlay a 55–70% dark scrim with a hole cut for the region. Either way the effect is the same: everything else recedes, the region owns the frame. Add the region outline (3–5 px at 1080p, accent color, slightly rounded corners) — the outline draws the eye before the label does. - Draw the callout (input: focus composition → output: callout keyframes)
From the region's edge, draw a leader line (2–3 px) outward to a label card placed in the nearest clean space — never over the region itself, never over another key detail. Leader line: 0.3–0.4 s draw, ease-out, with a small dot (6–8 px) anchoring it at the region edge. Label card: rounded rectangle, one title line (the region name, bold) + one detail line (≤12 words), fading/sliding in 0.35 s (ease-out, 10–14 px slide toward the region). Card background: solid, high contrast, readable at phone size. Total callout build: under 1 s. - Zoom if the region is small (input: callout → output: zoom keyframes; only when needed)
If the region is under ~8% of frame width, add a zoom: scale the base image 1.0 → 1.5–2.0 over 0.7–0.9 s (ease-in-out), centered on the region, BEFORE drawing the callout — zoom first, then outline, then leader, then card. The zoom is a dolly toward the evidence, not a gimmick: after the zoom the region must fill 25–40% of the frame. For chained callouts, zoom back out (0.6 s) before moving to the next region so the audience re-orients. - Hold, release, chain (input: complete callout → output: finished 10–25 s clip)
Hold the callout 2–2.5 s so the detail can be read. Release: fade the card and outline out over 0.3 s and restore the base image to full brightness — or chain to the next region (fade out 0.3 s, move to next region, repeat steps 2–4). For the final callout, hold 2.5 s then fade the whole frame 0.4 s. Export 1920×1080 or 1080×1080, 30 fps. Keep a still of each called-out state for slides and thumbnails.
