Low quality video is often caused by: (1) selecting a lower resolution tier — switch to 720p or 1080p for sharper output; (2) overly complex prompts with too many competing elements; (3) prompts that describe fast, chaotic motion — simplify the action for cleaner frames. Add 'high quality, sharp focus, cinematic, 4K' to your prompt. Also ensure your internet connection is stable during generation as interruptions can affect output quality.
