AI Solutions for Video Generation by LLMs
Practical Solutions and Value:
Video Generation by LLMs is a growing field with potential for long videos. Loong is an auto-regressive LLM-based video generator that can create minute-long videos.
Loong is trained uniquely from text and video tokens together, using short-to-long training and loss reweighing for balanced training. It can generate long videos based on text prompts.
To address challenges like imbalanced loss and error accumulation, the model uses progressive short-to-long training, video token re-encoding, sampling strategies, and super-resolution techniques.
Loong’s architecture includes a video tokenizer and a decoder-transformer system for predicting video tokens. It uses 3D CNN for video compression and transformer for autoregressive predictions.
The model produces videos with consistent appearance, motion dynamics, and natural transitions, making it valuable for visual arts, film production, and entertainment. However, it also raises concerns about potential misuse for generating fake content.
AI technologies like Loong can redefine workflows, enhance customer interactions, and improve efficiency. By implementing AI solutions in a phased manner and focusing on business KPIs, companies can leverage the benefits of automation opportunities.
