FAQs

1
1. Why do users find Seedream's generated images unsatisfactory?

Most dissatisfaction comes from vague prompts. For example, "a girl in a park" is too broad. You can include additional context or constraints in your image-to-text prompt, such as environment, lighting, style, or mood, to narrow the AI generator's focus and avoid unwanted results. For instance: "A cinematic portrait of a young woman in a red dress, smiling softly, sitting on a park bench at sunset with golden light, realistic 4K."

Users can also explore CapCut's Seedream showcases, which provide sample prompts with effect images that can be directly reused or adapted.
