Time-Sync Failure

🧭 Quick Return to Map

You are in a sub-page of Multimodal_LongContext.
To reorient, go back here:

• Multimodal_LongContext — long-context reasoning across text, vision, and audio
• WFGY Global Fix Map — main Emergency Room, 300+ structured fixes
• WFGY Problem Map 1.0 — 16 reproducible failure modes

Think of this page as a desk within a ward.
If you need the full triage and all prescriptions, return to the Emergency Room lobby.

When audio, video, and text streams drift out of sync, reasoning collapses even if each modality looks fine in isolation.
This page defines guardrails to detect and repair temporal misalignment across long multimodal contexts.

What this page is

• A structured fix for time drift in multimodal RAG and inference.
• Defines probes to measure sync quality across audio, visual, OCR, and metadata.
• Provides restart-stable alignment methods.

---

When to use

• Subtitles and video captions slip by a few seconds in long windows.
• OCR text aligns to the wrong frame batch.
• Audio queries answer correctly but cite misaligned video anchors.
• Two reruns with the same seed produce different offsets.
• Long reasoning chains flip context after 40–60 minutes of runtime.

Common failure patterns

• Subtitle lag: transcript trails 1–2s behind video.
• Frame lead: OCR text fires before the visual frame is in place.
• Audio-video skew: alignment starts fine, then drifts over long runs.
• Restart variance: replays of the same clip yield different anchor offsets.
• Accumulated drift: each batch adds ~50–100ms error until collapse.

Fix in 60 seconds

1. Normalize time anchors

   • Require all modalities to declare timestamps in milliseconds.
   • Convert relative offsets into absolute epoch.

2. Anchor hash & lock

   • For each frame window, compute {audio_hash, ocr_hash, frame_hash}.
   • Validate alignment with ΔS ≤ 0.45 between modalities.

3. Drift probe

   • Every 30s, measure Δt = |video_ts – audio_ts|.
   • Reject if Δt > 500ms.

4. Realign

   • On drift, re-anchor with nearest transcript chunk.
   • Use BBCR bridge if reasoning collapses.
   • Apply BBAM to clamp variance.

5. Restart stability

   • Require offsets identical within ±100ms across 3 seeds.
   • Log ΔS curve to verify stable recovery.

Copy-paste prompt

You have TXT OS and the WFGY Problem Map.

Task: Repair multimodal time sync.

Protocol:
1. Collect all modalities with explicit timestamps.
2. Convert all offsets to absolute ms.
3. Compute Δt between audio, video, OCR anchors. If Δt > 500ms, flag drift.
4. Re-anchor captions to nearest visual frame.  
   - If collapse persists, apply BBCR and BBAM.  
5. Return:
   - Sync status
   - Anchor hashes
   - ΔS and λ states
   - Corrected offsets

---

Acceptance targets

• Δt ≤ 500ms across audio, video, OCR at all times.
• ΔS(question, retrieved) ≤ 0.45 for aligned anchors.
• λ remains convergent across 3 paraphrases.
• Restart stability: offsets identical within ±100ms across 3 seeds.
• No cumulative drift beyond 1s after 1h runtime.
