By name: daily-single-video-pipeline description: Step-by-step daily_single video build with modular QA gates, spoken↔visual sync, social comparison clips, pytest, and validate-sync. Use for Fable-style pilots, social-comparison videos, A/V sync fixes, or end-to-end daily-single orchestration.
daily_single video pipeline (step by step)
Agent contract: read repo root AGENTS.md first — full BUILD_PIPELINE, PUBLISH_GATE, and QA-between-steps matrix.
Orchestrate build commands and QA gates in order. Do not skip gates after a step fails — fix, re-run that step, then re-gate.
Script/ hook contract: .cursor/skills/daily-single-video/SKILL.md
Spoken↔visual sync (cue assembly, 178 s regression): spoken-visual-sync.md
Social / viral research (X, Reddit, last30days): social-research-last30days.md
Reference pilot: examples/videos/anthropic-claude-fable-5-mythos-5/
Trust audit: examples/videos/anthropic-claude-fable-5-trust-audit/
Social comparison (same-prompt clips): examples/videos/anthropic-claude-fable-5-social-comparison/ — download clips first: bash scripts/download_social_videos.sh
Stage details: reference.md
Environment
zsh -c "source $(conda info --base)/etc/profile.d/conda.sh && conda activate test && cd /path/to/praisonaippt"
PROJECT=examples/videos/<slug>
Requires OPENAI_API_KEY for s02 VLM and s10 visual audit (unless offline). Set PRAISONAIPPT_QA_OFFLINE=1 to skip VLM-only stages in CI.
Master checklist
Copy and tick as you go:
- [ ] 0. Project has manifest.json + create-news handoff + beat-map
- [ ] 1. write-scripts (if segments missing)
- [ ] 2. QA pre_build → validate-qa --when pre_build
- [ ] 3. sync-assets
- [ ] 4. synthesise-vo
- [ ] 5. QA post_vo → validate-qa --when post_vo
- [ ] 6. bookend-media (00-hook, 99-outro)
- [ ] 7. record-canonical-scroll --duration 5 (inspect merge/qa/canonical_capture/framing-diagram.png — no wide gutters)
- [ ] 8. validate-canonical-scroll → must PASS (margins ≤12%, fill ≥55%, scroll ≤100 px/s)
- [ ] 9. QA pre_assemble → validate-qa --when pre_assemble (includes s11-canonical-capture)
- [ ]10. build-captions (merge/final.srt — before assemble when cue-aligned beats)
- [ ]11. assemble-beats (writes merge/timeline.json; beat-06/beat-01 use final.srt)
- [ ]12. validate-display (per-cue midpoint → visual)
- [ ]12b. validate-spoken-visual (montage/windows/charts/coverage/transitions + plain language)
- [ ]12c. validate-slide-quality → validate-engagement-assets → validate-viral-readiness
- [ ]12d. pytest tests/test_cue_slide_sync.py tests/test_spoken_visual_sync.py tests/test_slide_design_audit.py -q
- [ ]13. validate-hook-attention (1s frames ×5, then 2s until hook end)
- [ ]14. QA post_build → validate-qa --when post_build (includes s12-hook-attention, s03 charts/plain)
- [ ]15. Legacy confirm → validate-all && validate-sync --runs 3
- [ ]16. Publish gate → mer-vin upload skill (optional)
Cue-aligned rebuild (after script or safeguard-slide fixes): steps 10 → 11 → 12 → 12b → 12c only, or:
.cursor/skills/daily-single-video-pipeline/scripts/run-spoken-visual-gate.sh $PROJECT --assemble

Step-by-step commands
Replace $PROJECT with the video project root (directory containing manifest.json).
| # | Step | Command | Pass criterion |
|---|---|---|---|
| 1 | Scripts | daily-single -p $PROJECT write-scripts |
All segments/*/script.md exist |
| 2 | Pre-build QA | daily-single -p $PROJECT validate-qa --when pre_build |
PASS N/N — see reference.md |
| 3 | Sync assets | daily-single -p $PROJECT sync-assets |
HD clips + canonical images on disk |
| 4 | Voice-over | daily-single -p $PROJECT synthesise-vo --skip-existing |
All segments/*/narration.mp3 |
| 5 | Post-VO QA | daily-single -p $PROJECT validate-qa --when post_vo |
s05: script + narration per segment |
| 6 | Bookends | daily-single -p $PROJECT bookend-media --skip-existing |
heygen.mp4 hook + outro |
| 7 | Pre-assemble QA | daily-single -p $PROJECT validate-qa --when pre_assemble |
s00: hook/outro script, VO, HeyGen |
| 8 | Captions | daily-single -p $PROJECT build-captions |
merge/final.srt |
| 9 | Assemble | daily-single -p $PROJECT assemble-beats |
merge/final.mp4, merge/timeline.json |
| 10 | Display sync | daily-single -p $PROJECT validate-display |
cues_pass == cues_total |
| 11 | Spoken↔visual | daily-single -p $PROJECT validate-spoken-visual |
PASS — merge/spoken_visual_sync_report.json ok:true |
| 12 | Post-build QA | daily-single -p $PROJECT validate-qa --when post_build |
PASS 6/6 — display, AV sync, visual audit |
| 13 | Legacy gates | daily-single -p $PROJECT validate-all |
Prints PASS |
| 14 | Idempotent sync | daily-single -p $PROJECT validate-sync --runs 3 |
3 identical runs, spoken_visual=True |
Single stage debug:
daily-single -p $PROJECT validate-qa s08-av-sync
daily-single -p $PROJECT validate-spoken-visual
python -m praisonaippt.video_qa --project $PROJECT run s10-final-composite

When a gate fails
- Read
merge/qa/summary.json→failed_requiredand per-stagechecks. - For A/V mismatch at a timestamp: read spoken-visual-sync.md → multi-agent validation table.
- Fix the root cause (script, asset, assembly,
VISUAL_META), not the validator. - Re-run from the lowest affected build step (see table in reference.md).
- Re-run only the QA
--whenphases that cover changed artefacts.
Common fixes:
| Failure | Fix |
|---|---|
| s06 sparse_assets | Add beat-map images/clips or shorten script |
| s02 generic B-roll | Swap handoff clip or disable in protocol |
| build-captions crash | Proportional captions OK — s05 marks degraded: whisper |
| s08 section_boundaries | Re-run assemble-beats or build-timeline; compare beats/*.mp4 to timeline |
| s10 visual audit | Fix beat B-roll; re-run assemble-beats → post_build QA |
| s11 / validate-canonical-scroll | Browser error or wide gutters in hook — re-run record-canonical-scroll; open framing-diagram.png |
| s12 / validate-hook-attention | Error page, margins, or static first 5s — fix scroll capture then assemble-beats |
| validate-spoken-visual FAIL @~178s | Beat-06 cue assembly — see spoken-visual-sync.md |
| transitions_fail, windows_pass | Extend slide VISUAL_META topics or fix equal-thirds assembly |
| charts_fail on stat overlay | Add visual_focus; ensure cue midpoint inside chart window |
Multi-agent orchestration
Use subagents only where parallel or deep investigation helps. The parent agent keeps the checklist and runs gates sequentially.
| Situation | Agent | Task |
|---|---|---|
| Unknown project state, missing files | explore |
Map $PROJECT/segments, merge/, handoff paths; return gap list |
| Reported A/V mismatch at timestamp T | explore |
timeline.json + spoken_visual_sync_report.json + segment script; PASS/FAIL at T with evidence |
| Validator/assembler code review | generalPurpose |
Review cue_slide_sync, spoken_visual_sync, assemble; flag false positives |
| One stage fails with opaque error | explore |
Read merge/qa/*_report.json + relevant source; return fix steps |
| After code changes to validators | software-tester |
Run pytest + $PROJECT validate-spoken-visual |
| Full pilot rebuild (Fable-scale) | Parent + optional software-tester |
Parent runs steps 8–14; tester runs pytest in parallel after assemble |
Do not launch multiple agents to run the same validate-qa --when post_build (s10 runs visual audit once; duplicate runs waste API spend).
