Context-Aware Video Captioning

Created by team purpleCat on July 12, 2026

Antigravity Qwen3-VL OpenAI Gemini 3 pro Gemini AI

Video Captioning

This project is an adaptive AI video captioning agent that transforms raw video into distinct, personality-driven text. To prevent API timeouts on longer videos, the agent dynamically samples frames based on the video's total duration. It then feeds those frames to Fireworks AI using strict prompt engineering to generate four unique caption styles: formal descriptions, dry sarcasm, relatable internet humor, and cynical developer jokes. Finally, a bulletproof JSON extraction layer ensures the output is always formatted perfectly for production environments.
