πŸ” Comparison of New and Old Models Using Various Images

This paragraph presents a detailed comparison between the new Stable Video Diffusion 1.1 model and the previous model using different images. The speaker first discusses an image of a hamburger, noting that the old model performed better in this instance due to the consistency in the background and the static nature of the image. They then move on to an image of a floating market, which proved challenging for both models, but the new model maintained a slightly better consistency. The speaker also comments on the slower zooms and movements in the new model, which helps in maintaining consistency. The comparison concludes with an image of a cherry blossom tree, where the new model clearly outperforms the old one by keeping the scene more consistent, despite some imperfections.
