Researchers have developed a novel method for training AI models to understand video content using only text descriptions, bypassing the need for paired video-text data during training. This approach adapts existing Large Language Models (LLMs) like Qwen3_8B using text embeddings from models such as CLIP or LLM2CLIP. To bridge the modality gap between text and video at inference time, they introduced Nearest Entity Replacement (NER), a technique that maps video frames to text embeddings, significantly improving temporal localization performance on benchmarks like Charades-STA and QV-Highlights.
