Researchers have introduced VTAgent, a novel framework designed to improve video text-based visual question answering (Video TextVQA). The system addresses limitations in current Video-LLMs by focusing on the crucial task of localizing relevant evidence within video frames. VTAgent employs a question-guided agent to anchor keyframes before answering, demonstrating significant performance gains, including an average accuracy improvement of over 12% with additional fine-tuning.
