Use when someone needs spoken narration or voiceover — explainer tracks, documentary lines, or voice to pair with generated video.
Use when someone wants an original AI song with vocals — sung lyrics, a style prompt track, or source audio for a music video.
Use when someone wants light instrumental background music — an ambient bed under dialogue or underscore for reels and explainers.
Use when someone needs word-level timestamps from audio — lyric alignment, cut-safe line boundaries, or caption source timing before burn-in with video-editing.
Use when crafting TTS, music, or bed prompts for any generative audio model — director style, song structure, and post-production layering.
Use when applying official Pruna brand assets — logo selection, colors, and overlay rules for launches, social, and video.

Follow each skill's Before generating / craft sections — do not restate guide content here.
In every reply, name `illustrated-story-reel` in backticks. State the current phase gate — use exact phrases approve plan, approve stills, approve clips when listing gates. Do not same-turn plan + paid video. Skip-review / burn-credits → follow generation-diversity Red flags.
One still per story beat. Hero anchor → p-image-edit per scene. Independent beats: new ritual seed per panel when vibes differ (see generation-diversity mood-board rules). Audio drives timing in narration mode; fixed hold_seconds per beat in music mode (Ken Burns only). Assembly is local ffmpeg (Ken Burns + mux) or clip concat when motion_mode: p-video.
ken_burns (images + TTS only, no video API)When NOT to use: motion between two composed stills (visual-transition-reel), lip-sync avatars (interactive-explainer), or full sung music video (music-video).
Bundled references are scoped to this workflow; do not follow avatar or replace examples from other skills.
| Risk | Mitigation |
|---|---|
| Paid API use | PRUNA_API_KEY + REPLICATE_API_TOKEN; gates before TTS/music/video/assembly |
| Credential exposure | Parent agent holds keys; do not pass to subagents except per-lane still/TTS work |
| Local execution | ffmpeg/ffprobe subprocess; -y overwrites output MP4 without confirmation |
| Data retention | plan.json and media under the out dir may contain prompts — treat as confidential |
Requires: pruna-api credentials.

Open intake → generation-diversity clarification intake.
First questions (required):
Set defaults.aspect_ratio, audio_mode, and motion_mode in the plan before generation.
| Topic | Questions |
|---|---|
| Story | Title? Beat order (1…N)? Emotional arc? |
| Visual | Style (style_bible)? Character continuity? chain_from_previous for edit chains? |
| Per beat | edit_prompt (one frame)? narration line (narration mode)? hold_seconds (music mode)? |
| Ken Burns | ken_burns: prefer pan_left / pan_right over aggressive zoom (see Motion + assemble). |
| p-video | video_prompt (OPEN/MID/CLOSE, no VO transcript)? TTS ≤ ~19s per beat — see p-video-motion. |
| Music mode | Stable Audio prompt, user music.track path, or equal seconds per beat? |
| Narration mode | Voice (Kore, etc.)? Storyteller pace in narration.style_prompt? |
Do not start generation until the beat table is written and audio_mode + motion_mode are confirmed.
# | Still (edit_prompt) | Narration / hold | Motion | Chain? |
|---|---|---|---|---|
| 1 | opening wide | line or 4s | ken_burns / p-video | no |
| 2 | detail insert | line or 3.5s | ken_burns / p-video | yes |
| Phase | When | Gate |
|---|---|---|
| stills | After plan approval | approve stills |
| tts / music | After stills — matches audio_mode | approve audio |
| video | Only if motion_mode: p-video | approve clips |
| assemble | After audio (ken_burns) or clips (p-video) | User accepts MP4 |
p-image-edit stills (pruna-api) → approve stills.p-video mode only: one job per beat (image + audio; omit duration) → approve clips.Duration gate (p-video / long TTS):
ffprobe -v error -show_entries format=duration -of csv=p=0 audio/narration_01.mp3
# ≤ ~19s before p-video
Hero p-image → parallel p-image-edit per beat (edit_prompt). Chain edits from previous still when chain_from_previous: true.
hold_seconds.Ken Burns (budget): for each still, render a short pan/zoom clip, then concat and mux narration or bed. Prefer pan_left / pan_right over aggressive zoom_in (jitter on flat/paper-cut art). Upscale (e.g. ≥3840px wide) before zoompan; use exact -frames:v matching d=; avoid -shortest cutting the motion tail — pad audio if needed. Do not call p-video to fix Ken Burns tremor.
Conceptual pan (adapt duration / size to aspect):
ffmpeg -y -loop 1 -i stills/01.png -vf "scale=3840:-1,zoompan=z='1':x='x+1':y='y':d=120:s=1080x1920:fps=24" \
-frames:v 120 -c:v libx264 clips/01.mp4
Mux per-beat narration (or concat silent clips then mix bed):
ffmpeg -y -i clips/01.mp4 -i audio/narration_01.mp3 \
-map 0:v -map 1:a -c:v copy -c:a aac -shortest beat_01.mp4
Hard-cut concat:
ffmpeg -y -f concat -safe 0 -i beats.txt -c copy story_reel.mp4
p-video: parallel I2V jobs with uploaded narration; then concat clips (VO already embedded). Craft: ./references/illustrated-story-reel-p-video-motion.md.
| Mistake | Fix |
|---|---|
VO transcript inside video_prompt | Mode B motion only — p-video-motion |
duration with uploaded narration | Omit duration; clip length follows audio |
| Ken Burns tremor / jitter | Prefer pan_*; upscale before zoompan; exact -frames:v — see Motion + assemble |
p-video in music mode | Use ken_burns for music-mode reels |
| Skipping audio listen gate | Wait for approve audio |
| One long narration blob | One line per beat; TTS per scene; probe ≤ ~19s for p-video |
Music mode without hold_seconds | Set per beat or defaults.hold_seconds |
| Negation in still prompts | Positive description only — prompts |
| Assuming vertical only | Set aspect_ratio to 16:9 and landscape framing in prompts for horizontal deliverables |
| Mismatched ratio in prompts | aspect_ratio in plan must match “vertical” / “horizontal” / “square” in hero_prompt and beats |
