📖 Abstract

Large Language Models (LLMs) have been widely used in various tasks, motivating us to develop an LLM-based assistant for videos. Instead of training from scratch, we propose a module to transform arbitrary well-trained image-based LLMs into video-LLMs (after being trained on video data). To better adapt image-LLMs for processing videos, we introduce two design principles: linear transformation to preserve the original visual-language alignment and representative information condensation from redundant video content. Guided by these principles, we propose the Linear Video Tokenizer (LinVT), which enables existing image-LLMs to understand videos. We benchmark LinVT with six recent visual LLMs: Blip-3, Molmo, Mipha, InternVL2, Qwen2-VL and Aquila, show-casing the high compatibility of LinVT. Extensive experiments illustrate the effectiveness of LinVT in multi-modal video understanding while preserving the original image-comprehension capabilities.
