Episode notes
Limitation of Frame-by-Frame Video Processing
- Current multimodal LLMs treat video by processing many separate frames independently, missing temporal context.
- This approach leads to inefficiency and loss of understanding of video dynamics over time.
Temporal Encoder Builds Dynamic Memory
- The temporal encoder uses a state space model to fuse frames over time, building a dynamic memory.
- This enriches tokens with temporal information before entering the language model, improving video understanding.
Balance Token Efficiency and Info
- Use token reduction strategies that prune less important tokens while preserving critical video information.
- This compression reduces computational load without sacrificing understanding of the video's story.
