What Went Well
- Rhythmic Framework: The 5-phase “Pacing Guide” defined early in the process served as a successful source of truth for the entire team, ensuring visual and audio consistency.
- Technical Mentorship: Providing specific FFmpeg filter chains and technical debugging hints to the Tech Lead (Riggs) allowed us to bypass initial duration limitations and endpoint errors quickly.
- High-Signal Coordination: Maintaining a tight communication loop with the Creative Director (Idea) and Documentary Producer (Miller) kept the narrative focused on “The Sensory Core.”
What Didn’t Go Well
- Duration Latency: The initial 8s limit on raw video clips created a significant bottleneck, requiring a complex “extension + stitch” workaround for every scene to hit the 15s standard.
- Mograph Render Failures: The attempt to render HTML/Hyperframe code into MP4 containers hit environment-specific FFmpeg constraints (“Unrecognized option preset”), which delayed the final assembly.
Failure Modes & Bottlenecks
- Polling Loops: I initially fell into a directory-listing loop while waiting for assets. Breaking this with a “blocked” status and shifting focus to the Go assembly rig helped maintain progress.
- Static vs. Dynamic Rendering: The mismatch between the mograph agent’s dynamic HTML output and the assembly rig’s requirement for static containers (MP4) was the primary final-stage bottleneck.
Key Decisions Made
- The Static Pivot: Decided to pivot from dynamic MP4 renders to static PNG placeholders for titles and credits to bypass the FFmpeg “preset” error and ensure a timely delivery of the rough cut.
- The “Overhang Principle”: Mandated a 15s+ duration for all foundations to ensure frame-accurate sync for the 60 BPM “Clockwork Heartbeat” act.
Suggestions for Improvement
- Pre-Built Presets: Include a library of pre-validated FFmpeg filter strings (Noir, Jitter, Grain) in the
delta-assemblerrig from the start to reduce runtime logic complexity. - Standardized Durations: Establish the 15s+ temporal standard at Step 1 to avoid the need for manual extensions in later steps.
- Mograph Native Export: Ensure the mograph agent has a validated static export path (PNG/JPEG sequence) as a primary fallback for HTML rendering.
