    Error Handling

    Content Policy Warnings

    Generation Failures

    Timeout Errors

    Long videos or complex prompts may take extra time. Wait or try a shorter duration.

    Troubleshooting

    Video generation is taking too long

    Video generation typically takes 1-3 minutes depending on duration and quality. HD+ (1080p) videos take longer to generate.

    Video generation failed

    Try simplifying your prompt, reducing duration, or trying a different actor/template. If issues persist, contact support.

    Lip sync doesn't match perfectly

    Use shorter sentences and avoid complex words. The AI works best with natural, conversational language.
