a3-mascot-beat

name	A3-mascot-beat
description	motion-graphic scene archetype — oversized character / googly-eyes / face element on flat bg with looping micro-animation. wordless personality breath between content-heavy scenes. composes googly-eye-loop or character-loop on a single hero element.

A3 — mascot beat

Composes

• googly-eye-loop (the most common case) OR character-loop (for any other looping figure)
• bg-swap on entry (hard-cut into the mascot's bg)

Layout

canvas: 1080x1920 (or pack-specified)

mascot_zone:
  anchor: center
  origin: { x: canvas_w/2, y: canvas_h/2 }
  size_pct_of_canvas: 0.7         # mascot is BIG (eats 60-80% of frame)
  align: center
  bleed_off_canvas: true          # mascot often clips edges; that's intentional

Choreography

phase_1_appear:
  start_frame: 0
  effect: pop-in or hold (depends on pack)
  duration_frames: 4              # quick reveal — mascot scenes are mostly hold

phase_2_loop:
  start_frame: 4
  effect: googly-eye-loop OR character-loop
  loop: true
  cycle_frames: pack-specific (default 75 for eyes)

phase_3_hold:
  start_frame: last - 4
  duration_frames: 4              # let the loop settle before scene cut

Style pack compatibility

supported: [SP-A, SP-B, SP-E, SP-G]
preferred_in: [SP-A, SP-G]
incompatible: [SP-C, SP-D, SP-F]

Pack-specific overrides

SP-A (marshmallow)

• Default: googly-eye-loop with asymmetric_pupil_offset: 4 for the "alive" feel.
• Sclera #FFFFFF, pupils #0F0F0F.
• Bg: alternating pink/cream per pack rhythm.
• No text overlay.

SP-B (pinterest-saturated)

• Mascot is usually a hand-drawn doodle character (squiggle-driven, not eyes).
• Bg: saturated swatch from rotation pool.

SP-E (chaos-card)

• Character-loop on a 3D character (skating, dancing, jumping).
• Source asset required (mp4 or svg-animation).
• Slight ±5° tilt + music-beat-anchor.

SP-G (riso-illustration)

• Illustration character with illustration-bob + grain overlay.
• Often paired with a hand-drawn motion-line if the character is in motion.

Duration

duration_seconds: [1.4, 2.0]
default: 1.6

Mascot beats should NOT linger. Long enough for ~2 loop cycles, no more.

Quality Checks

• No text overlay on the mascot. The scene is wordless by definition.
• Mascot bbox can bleed offscreen (intentional — implies "personality larger than the frame").
• Loop cycles for at least 2 full cycles inside the scene duration.
• For googly-eyes: asymmetric_pupil_offset ≥ 2 so the eyes don't look like a "doll".

Failure Modes

• Mascot looks like a stamp. Missing the bob/loop. Verify character-loop or illustration-bob is wired.
• Scene feels too long. Reduce duration to 1.4-1.6s.
• User adds copy. Mascot beats are wordless — text breaks the archetype. Move copy to an adjacent A1 scene.
