    Important Information

    • Regarding the customization quality and effects of Video and Image Digital Humans

      • Video Digital Human: Based on the provided real-person video, AI training generates a Digital Human with expressions, movements, and facial expressions that rival real people — a "1:1 replica". Therefore, the quality of the video materials directly affects the customized Digital Human effect. Please ensure the quality of your recorded materials.
        If this is your first time recording, please strictly control the recording quality. Refer to the Video Digital Human Shooting Guide for video recording. Please carefully control the model's appearance, makeup, expressions, and manage factors such as on-site lighting, set design, green screen, and equipment to produce the best recording materials. If your model is not a professional, it is recommended to practice in advance by referring to the sample videos to ensure the best results during recording.
      • Photo Digital Human: Based on your provided photo materials, AI training can bring the image to "life" and generate a Digital Human avatar. Photos support real people, cartoons, virtual characters, and other styles. The generated avatar has clear speech, natural expressions, and supports a certain range of body movements, making it lively and vivid.
        To customize the best Image Digital Human, please strictly refer to the Image Digital Human Production Guide. Providing high-quality photos will produce better Digital Human results.

    • Regarding whether green screen background materials are required:
      If you need to change the Digital Human avatar background or generate a transparent background Digital Human avatar, please record in a green screen environment. If you do not need to change the background or use a transparent background, and only need to modify the person's lip movements, you can provide fixed background materials. Digital Humans with green screen backgrounds incur higher costs when generating content. Choose based on your actual scenario needs.

    • Regarding the output specifications of customized Digital Humans:
      Please note that the materials you provide directly determine the output specifications of your Digital Human. For example, if your Digital Human material is a 16:9 image, the content output when driving the Digital Human will also be 16:9. Outputting other specifications may affect the Digital Human effect.
      Therefore, before providing materials, confirm the subsequent Digital Human usage effect based on your UI layout (landscape, portrait, aspect ratio, resolution, etc. For detailed specification information, please refer to the Image Digital Human Production Guide and Video Digital Human Production Guide). You can use images first to replace the Digital Human to confirm the UI effect, ensuring the final customized Digital Human meets expectations.
