•SentrySearch utilizes a novel contrastive learning approach that aligns visual temporal features directly with vector space, bypassing the latency and error propagation associated with traditional OCR or ASR-based indexing.
•The tool leverages Qwen3-VL's native multi-modal architecture, which was specifically fine-tuned on high-density video-text pairs to maintain semantic coherence across long-form video sequences without needing frame-by-frame captioning.
•The implementation includes a proprietary 'Temporal-Aware Chunking' algorithm that dynamically adjusts clip boundaries based on visual scene changes, optimizing the precision of the auto-trim feature before vector insertion into ChromaDB.

Architecture: Utilizes Qwen3-VL's vision encoder (ViT-based) coupled with a temporal pooling layer to compress video segments into fixed-length embeddings.
Indexing: Employs ChromaDB's HNSW (Hierarchical Navigable Small World) index for sub-millisecond retrieval of video segments.
Memory Optimization: Uses 4-bit quantization (GGUF/EXL2) to fit the 8B model into 18GB VRAM/RAM, allowing for local inference on consumer-grade hardware.
Input Handling: Supports common video formats (MP4, MKV, AVI) via FFmpeg integration, which handles the initial frame extraction and temporal segmentation.
