Very long paragraphs may have inconsistencies, and extremely complex layouts might require multiple iterations. Break complex text into simpler elements and generate multiple versions to select the best result.
Very small text sizes may lose clarity. For best results, use medium or large text sizes. If small text is necessary, consider using higher resolutions and clear font styles.
Mixed language text can be challenging. It's recommended to generate separately or use a primary language for best results. Consider creating multiple versions for different language audiences.
Some complex scenes may require multiple generations and prompt optimization to achieve ideal results. Use detailed prompts with clear style descriptions to improve first-generation quality and reduce iteration needs.
