Livepeer Agent iterates fast in FLUX.3 draft mode, then upgrades the chosen takes to final quality and ships a stitched campaign film. ## What you'll get - **A 3–6 shot campaign film** — coherent visual language, platform-ready export - **Draft takes you can pick from** — cheap iteration before committing spend - **A final-quality upgrade** — either “re-render final” or “enhance this exact draft” - **A stitched MP4** — real finishing (concat + export), not a folder of clips ## Tell the agent about the campaign film ```yaml campaign_goal: # 1 sentence: what the film must sell product_image_url: # OPTIONAL https URL (use as i2v first frame for the hero shot) script_beats: # 3–6 bullet lines (hook → proof → payoff → CTA) style_brief: # 1–2 sentences (lighting, camera, grade, typography) shot_count: 4 # 3–6 seconds_per_shot: 6 # 4–10 recommended aspect_ratio: 16:9 # "16:9" or "9:16" max_spend_usd: 12.00 # hard ceiling output_slug: # kebab-case filename prefix ``` ## Conventions (how the agent must run) 1. **Spend gates**: - STOP before the **draft batch** (cheap but still billable). - STOP before any **final upgrade** (can dominate cost). 2. **Identity gate**: after drafts, STOP and lock the visual direction (don’t “fix” by random re-rolls). 3. **Final review gate**: STOP before stitching/export. ## The stages ### Stage 0 — Confirm + shot plan (no render) Turn `script_beats` into `shot_count` shots (one line each): what we see + what text (if any) appears. **STOP**: “Plan looks right? (approve / edit [shot #])” ### Stage 1 — Cost preview for drafts (no render) Estimate draft spend: - Draft video is **$0.06 / second** (`flux-3-draft-t2v|i2v|transition|keyframes`) - Draft extend is **$0.12 / second** (`flux-3-draft-extend`) - Draft batch cost ≈ `shot_count × seconds_per_shot × 0.06` (plus any optional extends) If it risks exceeding `max_spend_usd`, propose fewer shots or shorter shots. **STOP**: “Approve spend to generate drafts? (approve / reduce / abort)” ### Stage 2 — Generate draft takes (FLUX.3 draft) Render each shot as a draft: - If `product_image_url` is set, use **one** hero shot as `flux-3-draft-i2v` from that image. - Other shots use `flux-3-draft-t2v`. **STOP**: “Pick drafts to upgrade: (upgrade [shot #…] / redo [shot #…] / abort)” ### Stage 3 — Identity + direction lock (no render) Summarize what’s now locked: - palette/grade (from `style_brief`) - product identity constraints (if any) - pacing (seconds_per_shot) **STOP**: “Direction locked? (approve / adjust style_brief)” ### Stage 4 — Upgrade to final quality (two options) For each selected shot, pick one upgrade path: - **Option A (cheaper, re-render final):** re-run with `flux-3-t2v` / `flux-3-i2v` at 1080p using the refined prompt. - **Option B (same motion, expensive):** `flux-3-draft-enhance` using the draft’s `draft_cache_url` from `structuredContent.draft_cache_url` (**$0.29 / second**). The agent must show a per-shot cost estimate before running upgrades. **STOP**: “Approve spend for final upgrades? (approve / switch option / skip a shot)” ### Stage 4B — Optional keyframes take (demonstrate precise control) When a shot needs **exact timing** (e.g. three beats in one 10s clip), run `flux-3-keyframes` instead of a free-form t2v. - Pick 3 stills (they can be your own images, or keyframes you generated earlier). - Use the proven frame indices from the registry example for a 10-second clip: 0, 120, 240. **STOP**: “Keyframes shot worth it, or stick to normal shots? (use keyframes / skip)” ### Stage 5 — Optional extend (only if needed) If the film is too short, extend a chosen clip with `flux-3-extend` (or `flux-3-draft-extend` for a cheap test). Pricing: `flux-3-extend` **$0.41 / second**, `flux-3-draft-extend` **$0.12 / second**. **STOP**: “Extension ok? (approve / undo extension)” ### Stage 6 — Stitch + export (deterministic) 1) `ffmpeg-concat` in order (hard cuts) 2) If `aspect_ratio: 9:16`, run `ffmpeg-export` with `preset:"tiktok-portrait"`. If `aspect_ratio: 16:9`, skip export (stitched output is already correct). **STOP**: “Export the final campaign film? (approve / reorder shots)” ### Stage 7 — Deliver Return: - final MP4 URL - per-shot URLs (draft + final) - the exact prompts and upgrade choices (so this is reproducible) ## FINAL OUTPUT Print exactly: ``` ✅ Final campaign film: ✅ Shots (final): ✅ Shots (drafts): ✅ Upgrade ledger: Total spent: $X.XX (ceiling $max_spend_usd) ``` ## AFTERCARE - If the film works: rerun with a different hook (only Shot 1) and keep the rest locked. - If you need a longer cut: use `flux-3-draft-extend` first (cheap), then upgrade only if the extension is worth it. ## Notes for the agent (exact calls; keep compact) - Draft: `mcp__livepeer-agent__run_capability({ capability:"flux-3-draft-t2v" | "flux-3-draft-i2v", prompt, source_url?, inputs:{ duration: seconds_per_shot } })` → read `structuredContent.draft_cache_url` (draft endpoints do not accept `resolution`) - Enhance: `mcp__livepeer-agent__run_capability({ capability:"flux-3-draft-enhance", inputs:{ draft_cache_url } })` - Keyframes: `mcp__livepeer-agent__run_capability({ capability:"flux-3-keyframes", prompt, inputs:{ resolution:"720p", duration: 10, keyframes:[{ image_url:"", frame_index:0 },{ image_url:"", frame_index:120 },{ image_url:"", frame_index:240 }] } })` - Draft extend: `mcp__livepeer-agent__run_capability({ capability:"flux-3-draft-extend", prompt:"continue seamlessly", inputs:{ video_url:"", duration:"auto" } })` (draft endpoints do not accept `resolution`) - Stitch: `mcp__livepeer-agent__run_capability({ capability:"ffmpeg-concat", inputs:{ clips:[...], transition:"cut" } })` - Export (9:16 only): `mcp__livepeer-agent__run_capability({ capability:"ffmpeg-export", inputs:{ source_url:"", preset:"tiktok-portrait", crop:"center-crop" } })`
