Tutorial — Capturing Idle Takes

What to capture so the figure looks alive while waiting, listening and thinking. The Q&A tutorial layers base idles, fidgets, breathing, gaze and hand poses. This page is the shot list and directing notes that feed those layers.
Draft. Written from our Q&A idle design and Epic's capture guidance. The director and technical animator validate it after the first idle session. Correct any setting names here.
1. The shot list
Per figure, per posture (standing; seated at a desk or table):
| Item | Count | Length | Layer it feeds |
|---|---|---|---|
| Waiting takes | 3–6 | 30–60 s each | Base idle (random sequence) |
| Fidgets | 8–12 | 2–6 s each | Additive fidgets, every 8–25 s |
| Breathing | 2 | 20–30 s | Additive breathing on spine and clavicles |
| Weight shifts | 4–6 | 3–6 s | Transitions between waiting takes |
| Look-arounds | 4–6 | 3–5 s | Gaze variety; the Look At node does the rest |
| Thinking / considering | 4–6 | 1–2.5 s | Thinking state before first audio |
| Listening posture | 2–3 | 10–20 s | Listening state |
| Turn to visitor | 2 | 1–2 s | Waiting → Listening |
Thinking clips must be short. First audio should arrive within about 1.5 s (AI Mind — Process), so a thinking clip that runs longer will be cut off.
2. Fidgets per figure (historian approves the list)
| Maria Mitchell (1847) | Whaling captain | Lucretia Mott |
|---|---|---|
| Glance at the telescope | Glance at the sky or the window (weather) | Hands resettle in the lap |
| Straighten papers on the desk | Thumb along the waistcoat edge | Small nod, as if hearing a thought |
| Adjust shawl on the shoulders | Weight onto the back foot, hands behind back | Smooth the apron or skirt |
| Touch the pen, not pick it up | Check a pocket watch (non-metal proxy on suit days) | Turn a page |
Avoid modern habits: checking a phone-like object, tight crossed arms, hair-flicks, stretching the arms overhead.
3. Directing the waiting takes
- Give the performer a reason to wait. "You have come to the Atheneum early; the hall is filling." A waiting take without a situation turns into posing.
- Low energy, but not asleep. Blinks, small breaths, eyes that settle and move on.
- No big events. Save big actions for fidgets, so they can be timed separately.
- Stay near the mark. Feet may shift; they must come back within a few centimetres.
- Posture holds. In stays the torso stays upright; the performer rests by shifting weight, not by slumping (Tutorial — Period Movement Coaching).
- One long take is better than many short ones. Ask for 90 s and cut the best 30–60 s.
4. Loopability rules
- Start and end every base idle on the rest pose (
rest_standorrest_seat, shared with Tutorial — Gesture Library and Tags).- Call "back to rest" 5 s before the end of the take.
- Hold still for 2 s at each end. Cleanup trims to matching frames.
- Same foot placement at start and end. Mark the floor.
- Fidgets and weight shifts: start and end on rest; these are additive or short full-body pieces.
- Breathing clip: capture a quiet, even stretch; cleanup cuts one breath cycle-aligned loop (inhale start to inhale start).
5. Listening and thinking
- Listening: turned towards the visitor, still, a slight lean in, a small brow lift. Hands stop moving. Capture a version that holds for 20 s without looking frozen: tiny nods, a blink rhythm.
- Thinking: a look aside, a touch of the chin, a glance down at the desk, a slight intake of breath. No mouth movement and no sound; filler speech is not allowed.
- Record each thinking clip starting from the listening pose and ending ready to speak.
6. Recording notes
- Same costume proxy and props as the monologues, so posture matches.
- Slate each take as idle:
Mitchell_20261014_IDLEstand_T03(Tutorial — Running a Capture Day). - Face: record face on waiting and listening takes too. Blinks and small eye moves are what sell "alive".
- Suit drift: long takes show inertial drift. Recalibrate before each 60 s block.
- Markerless route: idles are a good first use of Tutorial — Single-Camera Body Capture, but check the feet; floating feet show badly on a still figure.
7. Delivery
- Naming:
AS_<Figure>_Idle_<Posture>_Wait_<##>AS_<Figure>_Idle_<Posture>_Fidget_<name>AS_<Figure>_Idle_<Posture>_Think_<##>,_Listen_<##>,_Breath
- Cleanup: loop points, locked feet, hands from the hand pose library (Tutorial — Hand Pose Library for Gestures).
- Additive settings on fidgets and breathing as in Tutorial — Gesture Library and Tags.
- Hand to the Unreal engineer with a short CSV: name, layer, length, posture, historian approval date.
- The Animation Blueprint and State Tree in Tutorial — Authoring a Q&A Experience with Ambient Idle take it from there.
8. Practice exercise
Capture three 60 s waiting takes for Maria Mitchell seated at a desk, plus four fidgets and two thinking clips. Build the idle in a test Animation Blueprint and leave it running for 30 minutes. Note every moment a loop or a repeat is visible, and capture replacements for the worst two.
