Animate (A-Roll)

Turns first frames into talking head clips with synced lip movement and audio. Image-to-video is the default — text-to-video is the fallback.

Fallback chain: Sora 2 (fal.ai) -> Kling 3 (fal.ai) -> Kling 3 (Replicate). Use --provider kling to skip Sora entirely (for when Sora is sunset).

Prerequisites

• First frame approved (from /first-frame)
• Script with [A-ROLL] segments tagged (from /persona)

Motion Prompting

Read references/motion-prompting.md for the structured prompt format. Use labeled fields — not prose paragraphs:

• Camera — handheld energy, micro-shake, slight reframe
• Subject — keep generic (first frame defines appearance). Detailed facial descriptions trigger content safety filters
• Dialogue — include actual script lines. Sora generates synced lip movement + audio
• Audio — describe the RESULT not the gear. "Clean natural podcast audio, voice close and present, subtle room tone" works. Naming specific mics doesn't.
• Environment & light — practical light, deep focus, real-world setting
• Style & mood — iPhone selfie-camera realism, not cinematic

Generation

USE THE SCRIPTS. DO NOT construct API calls manually. Scripts handle provider routing, field names, polling, downloading, and error handling.

# Image-to-video (RECOMMENDED — first frame locks the face)
bash scripts/generate-clip.sh \
  --provider fal \
  --image workspace/campaigns/<slug>/frames/frame1.png \
  --prompt-file workspace/campaigns/<slug>/motion-prompt.txt \
  --output workspace/campaigns/<slug>/clips/a-roll-01.mp4 \
  --log-file workspace/campaigns/<slug>/output-log.md \
  --label a-roll-01 \
  --seconds 8 --aspect-ratio portrait

# Text-to-video (fallback — no first frame)
bash scripts/generate-clip.sh \
  --provider fal \
  --prompt-file workspace/campaigns/<slug>/scene-prompt.txt \
  --output workspace/campaigns/<slug>/clips/a-roll-01.mp4 \
  --log-file workspace/campaigns/<slug>/output-log.md \
  --label a-roll-01 \
  --seconds 8 --aspect-ratio portrait

# Kling direct (skip Sora — use when Sora is sunset)
bash scripts/generate-clip.sh \
  --provider kling \
  --image workspace/campaigns/<slug>/frames/frame1.png \
  --prompt-file workspace/campaigns/<slug>/motion-prompt.txt \
  --output workspace/campaigns/<slug>/clips/a-roll-01.mp4 \
  --log-file workspace/campaigns/<slug>/output-log.md \
  --label a-roll-01 \
  --seconds 8 --aspect-ratio portrait

# Replicate Sora (legacy — may stop working when Sora is sunset)
bash scripts/generate-clip.sh \
  --provider replicate \
  --image workspace/campaigns/<slug>/frames/frame1.png \
  --prompt-file workspace/campaigns/<slug>/motion-prompt.txt \
  --output workspace/campaigns/<slug>/clips/a-roll-01.mp4 \
  --log-file workspace/campaigns/<slug>/output-log.md \
  --label a-roll-01 \
  --seconds 8 --aspect-ratio portrait

API Reference

Read references/sora-api.md for endpoint details, queue workflow, field names, and duration options. Sora fal.ai supports 4/8/12/16/20s. Kling supports 3-15s (durations >15s are auto-clamped). Replicate Sora is limited to 4/8/12.

Content Filter Handling

Sora's content filter runs AFTER generation — can fail at 99%. If blocked:

• Soften the motion prompt (keep first frame)
• Remove any potentially sensitive descriptions
• Retry with adjusted prompt
• Or use --provider kling — Kling has no content safety filter

Key Findings

• Include actual script in Dialogue field — Sora generates synced lip movement
• For podcast audio: describe the RESULT, not the gear
• Keep Subject descriptions generic — the first frame already defines appearance
• fal.ai is primary provider; Kling 3 is auto-fallback when Sora fails or is sunset
• Use --provider kling to skip Sora entirely

File	Purpose
workspace/campaigns/<slug>/frames/frame1.png	Canonical face — fed to Sora i2v to lock creator identity
workspace/campaigns/<slug>/scripts/<format>-script.md	A-roll segments, dialogue, shot timing

workspace/creators/creator-<name>.md	Fallback if no campaign-specific profile exists

Context loading

🎥 Animate context loaded:
  ✓ First frame: workspace/campaigns/ridge-q1/frames/frame1.png
  ✓ Script: talking-head (A-roll segments: 3)
  ✓ Creator: Maya
  ✓ Campaign: ridge-q1

Contract

Input

• Required: approved frame1.png plus a script with [A-ROLL] segments
• Optional: creator profile details, alternate prompt file, fallback provider
• Format: workspace image and markdown files plus motion prompt text
• Source: /first-frame, /persona, and references/motion-prompting.md

Output

• Produces: one A-roll clip per [A-ROLL] segment plus append-only generation logs
• Format: MP4 files in workspace/campaigns/<slug>/clips/ and rows in output-log.md
• Default behavior: use Sora image-to-video with the approved first frame; use text-to-video only as a fallback when no usable frame exists
• Downstream use: /b-roll and /assemble

Validation

• Pre-conditions: first frame is approved, script is tagged correctly, and the prompt includes the actual dialogue
• Post-conditions: local MP4 is saved, creator identity holds, and lip movement/audio feel believable enough to cut into a final video
• Failure checks: reroll or adjust the prompt if content filters fail, the hands/face break realism, or the clip is too synthetic to pass downstream

Output

• A-roll clips (MP4) in workspace/campaigns/<slug>/clips/
• Each clip named a-roll-<segment>.mp4 corresponding to an [A-ROLL] script segment
• Generation params logged to workspace/campaigns/<slug>/output-log.md

Next Step

A-roll done → run /b-roll for environment shots, or /assemble if no B-roll needed.
