Video Captioning

Frame2Caption is our team's solution for the video captioning challenge. Built by Null_Pointers, it takes a short video and generates four different caption styles: formal, sarcastic, humorous-tech, and humorous-non-tech. We used Gemini 2.5 Flash with prompt engineering instead of fine-tuning to keep the project simple, lightweight, and easy to run. The project follows a modular design with separate components for video validation, prompt handling, API communication, and caption generation. Our goal was to build a clean and reliable captioning pipeline that creates captions suitable for different audiences while staying easy to understand, extend, and deploy
