• Quality: Pure comedy tone maintained. Audio/Video in sync.
• Action: Production complete. Initiating retros.

[2026-05-17 21:58] - Step 7 Friction: Pixel Format Bug

• Bug: Video hangs after opening title; audio continues.
• Root Cause: Identified pix_fmt mismatch (yuv420p vs yuv444p) via ffprobe.
• Action: Instructed iota-editor to re-encode main film to yuv420p and re-concat.

[2026-05-17 22:08] - Detailed Technical Note: Pixel Format Normalization Fix

• Issue: Final concatenated video (opening + main + closing) would hang on the last frame of the opening title card while audio continued.
• Root Cause Analysis:
  • Opening/Closing segments were rendered as yuv420p (standard for H.264/AAC distribution).
  • Main film (Step 7 rough cut) was rendered as yuv444p (likely due to high-fidelity defaults in the synthesis-to-assemble path).
  • The genmedia-assemble concat tool uses the ffmpeg concat demuxer, which expects uniform stream properties. When the decoder encountered a change from 420p to 444p mid-stream, it stalled the video pipeline while the audio clock remained in sync.
• Resolution Path:
  1. Identfied the mismatch via ffprobe -show_entries stream=pix_fmt.
  2. Re-encoded the main film to the distribution standard: ffmpeg -i ... -pix_fmt yuv420p -c:v libx264 -crf 18 -c:a copy ...
  3. Re-ran the concatenation.
  4. Performed a 4-point ffprobe audit (Title, Start, Middle, End) to confirm uniform yuv420p throughout.
• Lesson Learned: Always normalize pixel format (standardizing on yuv420p) before the final concatenation step to ensure player compatibility and prevent demuxer stalls.

[2026-05-17 22:12] - Editorial Convention Note (from Preston)

• Observation: It would be good convention to have a narrator introduce some opening context for most films.
• Impact: Helps provide immediate narrative grounding and ensures subsequent scenes “fall into place” for the viewer.

[2026-05-17 23:12] - Review Update: External Reviewer

• Status: Preston is working with an external reviewer.
• Action: Standing by for a message and instructions from the external reviewer. Team is alerted.

[2026-05-17 23:16] - Selective Reshoot Initiated

• Status: Executing dialogue/narration alignment reshoot based on external review.
• Scope: Reshooting Shot 6 & 16; inserting one new compound dialogue shot.
• Goal: Resolve visual-audio conflicts and improve conversational realism.

[2026-05-17 23:26] - Reshoot Assets Verified: Final Render Initiated

• Success: 3 new video clips (720p, 8s) and 4 audio stems verified.
• Action: Instructed Editor to integrate assets and render Final Master v2.
• Coordination: Messaged Preston and coordinator with the final stretch update.

[2026-05-17 23:33] - Production Milestone: DEFINITIVE WRAP

• Success: FINAL MASTER v2 rendered, verified, and approved.
• Improvement: Reshoots successfully resolved narrator/visual conflicts and added conversational depth.
• Technical: Uniform yuv420p distribution standard confirmed.
• Action: Production concluded. Releasing team members.

[2026-05-18 01:30] - Playbook Integration: Dialogue & Narration Guidelines

• Task: Integrated findings from the Iota dialogue analysis into the global video production playbook and role-specific guides.
• Updates Made:
  • Playbook: Added “Visual-Audio Agreement” global constraint and Appendix Checklist.
  • Idea Person: Added classification system ([DIALOGUE], [VO], etc.), dialogue quality guidelines, and timing hint requirements.
  • Tech Lead: Added motion prompt alignment rules (VO-safe rule).
  • Editor: Added temporal mapping and sync requirements using timing hints.
• Goal: Codify the “Iota Breakthrough” (Tone as a Safeguard) for all future teams.

[2026-05-18 02:42] - Action Item: Built-in Audit Logging

• Observation: Generation prompts were lost when sub-agents were cleaned up (truncated gen.log).
• Decision: Tools should internally handle prompt logging to a persistent central location.
• Action: Instructed tool-maker to implement built-in audit logging and require a TEAM_NAME env var.

[2026-05-18 02:44] - Update: Audit Logging Implementation

• Decision: TEAM_NAME env var will be strictly required. Tools will error if unset.
• Scope: genmedia-image, genmedia-video, genmedia-voice, genmedia-music.
• Log Target: Centralized GCS prompts.jsonl + local fallback.
• ETA: ~2 hours.

[2026-05-18 02:46] - Action Item: Automatic pix_fmt Normalization

• Decision: Standardize all output on yuv420p for maximum compatibility.
• Action: Instructed tool-maker to build auto-normalization into genmedia-assemble.

[2026-05-18 02:49] - Status Update: Audit Logging Verified

• Success: Verified that generation tools now error if TEAM_NAME is missing.
• Verification: Successful voice generation test correctly logged prompt and parameters to /workspace/tools/audit/iota/prompts.jsonl.
• Action: Standing by for tool-maker to complete Auto-Normalization in genmedia-assemble.

[2026-05-18 02:51] - Update: Auto-Normalization Verified

• Success: genmedia-assemble successfully standardized yuv444p input to yuv420p output.
• Resolution: The video playback hang bug is now permanently mitigated through tool-level automation.

[2026-05-18 02:57] - Playbook Integration: Safety Filter Guidelines

[2026-05-18 03:05] - Playbook Integration: The Scene-Shard Strategy

• Task: Integrated multi-subagent workload sharding into the Editor role guide.
• Guideline: Limit sub-agents to one scene (max 12 frames/6 shots).
• Outcome: Context isolation and parallel verification to prevent agent stalls.

[2026-05-18 03:25] - Playbook Integration: Working Directory Mandate

• Task: Integrated pathing requirements into global and role guides.
• Outcome: Explicit mandates for Editors to set the correct working directory before assembly to ensure relative path resolution.

[2026-05-18 03:26] - Action Item: Automatic Audio Padding
