| Medium | GrooveSquid.com (original content) | Medium Difficulty Summary Our research proposes an innovative approach to enhance text-to-video (T2V) models by distilling a consistency model from a pre-trained T2V model. We introduce T2V-Turbo-v2, which integrates various supervision signals, including training data, reward model feedback, and conditional guidance, into the distillation process. Our ablation studies highlight the importance of tailoring datasets to specific learning objectives and learning from diverse reward models for enhancing visual quality and text-video alignment. We also explore the design space of conditional guidance strategies, which involves designing an effective energy function to augment the teacher ODE solver. By extracting motion guidance from training datasets and incorporating it into the ODE solver, we demonstrate the effectiveness of this approach in improving motion quality with improved metrics from VBench and T2V-CompBench. Our proposed method achieves a state-of-the-art result on VBench, surpassing proprietary systems like Gen-3 and Kling, with a Total score of 85.13. |
| Low | GrooveSquid.com (original content) | Low Difficulty Summary We’re trying to make video generation better by using an old model as a teacher to learn from a new one. We call this new approach T2V-Turbo-v2. It’s like getting a superpower boost that helps the new model create more realistic videos with good motion and alignment. To do this, we use different types of guidance, like having the new model try to match what the old model did. This makes the new model learn from its mistakes and get better at making videos. We tested it and it worked really well! It even beat some other systems that are usually pretty good at video generation. |
