| # ------- Regarding the issue that I2V tends to produce very slow motion at the beginning: | |
| # ------- During training, we did not construct the corresponding history context format (i.e., first-frame anchor + last-frame), | |
| # ------- which means the current I2V inference relies heavily on the model’s zero-shot capability. | |
| # ------- Incorporating this data format during training should significantly improve performance. | |
