The evaluation of Zeroscope-v2-XL involved generating videos directly at 1024x576 resolution and upscaling from lower resolutions. Direct generation showed mixed results, with some videos exhibiting noise and artifacts, especially in complex scenes like urban environments with multiple moving objects. However, simpler scenes, such as underwater shots, displayed better stability and clarity.

Direct Generation at 1024x576

Direct generation at 1024x576 resolution produced videos with variable quality. While some scenes, like underwater sequences, were stable and clear, others, such as urban chase scenes, suffered from noise and inconsistent motion. The model struggled with fluid character movements and dynamic camera work, though colors remained vibrant. Memory constraints were a significant challenge, with optimal performance requiring at least 16GB VRAM.

Challenges in Complex Scenes

Complex scenes, particularly those with multiple moving elements, posed difficulties for the model. For example, a chase scene in a crowded market had recognizable elements but lacked fluidity in character movements. The model's sensitivity to prompt complexity was evident, as simpler prompts yielded better results compared to intricate scenarios.

Upscaling from Lower Resolution

Upscaling videos from 576x320 to 1024x576 using Zeroscope-v2-XL improved detail and reduced noise compared to direct high-resolution generation. However, artifacts and inconsistencies from the lower resolution, such as jerky movements, persisted but were less noticeable due to the higher resolution. This method proved more efficient in handling resource constraints while maintaining visual quality.

Benefits of Upscaling

Upscaling provided a balance between resource usage and output quality. By generating at a lower resolution and then upscaling, the model could handle more complex scenes without exceeding memory limits. The upscaled videos showed enhanced details and smoother transitions, though the initial generation quality still influenced the final output.

Conclusion & Next Steps

The evaluation highlights the strengths and limitations of Zeroscope-v2-XL. Direct generation at high resolution is resource-intensive and inconsistent for complex scenes, while upscaling offers a more practical approach with better results. Future improvements could focus on optimizing the model for complex prompts and reducing memory requirements to enhance performance across all scenarios.
