Multimodal Pipeline for Long-Horizon Gameplay Analysis

Long-form gameplay analysis breaks when we treat context size as the only scaling lever. A better strategy is systems-oriented: separate perception, indexing, retrieval, and reasoning.

Pipeline Summary

The architecture uses dedicated components for each modality and keeps expensive perception off the critical response path.

Video -> Segmentation/Temporal Features -> Timeline Index
Audio -> ASR/Embeddings -------------> Retrieval Layer
Text Query -> Hybrid Search ---------> Reasoning Model

This makes long-horizon question answering feasible without saturating a single model with raw frames.

Key Design Principles

1. Keep perception modular so components can be upgraded independently.
2. Index once, retrieve many times.
3. Tune reasoning models on structured evidence, not raw timelines.

Outcome

The result is better temporal coherence and more stable multi-turn reasoning over 10+ minute gameplay sessions.
