Description
Hi, thanks for your great work! I’m using the model for video super-resolution with a fixed 1.5× upscale ratio(480p -> 720p), which I can’t change due to task requirements. The overall results are good, but local facial expressions and text sometimes appear distorted (similar to the issue in #25). I’ve already experimented with several hyperparameters (such as sparse ratio and local range), but the results didn’t show much difference. Are there any other settings or parameters I could adjust to improve detail fidelity in this case?

Research direction
No file, test, or entry point is identified in the issue. Reproduce the fixed 1.5× 480p-to-720p case, compare the facial and text distortions with issue #25, and review the reported sparse-ratio and local-range experiments. Done means identifying a supported setting that improves detail fidelity or documenting that the limitation remains.
