📄 About Ovi Image-to-Video

Uniquely, this model supports special prompt tags that allow fine control over speech, voice style, and environmental audio details, elevating the realism and emotional impact of generated content.
With Ovi Image-to-Video, users can upload any image and craft a text prompt that specifies not only what the avatar will say but also how it will sound. By embedding tags such as <S>speech<E> for spoken phrases and <AUDCAP>audio description<ENDAUDCAP> for nuanced audio cues, users can direct the model to produce ASMR-style voices, soft whispers, or any desired vocal effect. This flexibility makes the tool ideal for creating personalized, engaging videos where the avatar’s audio and visual cues are perfectly aligned.
The model intelligently animates facial features, mouth movements, and head gestures to match the input speech, ensuring a high level of realism and emotional expressiveness. The synchronized audio is not only clear and natural but can also be customized to include room acoustics, voice tones, and subtle audio effects, making the output suitable for a wide range of creative and professional applications. Additionally, Ovi Image-to-Video includes negative prompt options for both video and audio, allowing users to avoid unwanted artifacts such as jitter, blur, distortion, robotic sounds, and echoes.

Whether you are producing video explainers, virtual spokespersons, AI-driven ASMR content, or enhancing multimedia presentations, this model streamlines the workflow by eliminating the need for manual animation or professional voice recording. Its pay-as-you-go credit system also ensures that users only pay for what they use, making cutting-edge video generation technology accessible and scalable for projects of any size.

Frequently Asked Questions
High-resolution, clear images with a visible face and neutral background yield the most realistic and expressive results. Avoid blurry or heavily obstructed images for optimal output.
Use the specialized prompt tags:
speech to specify the words and audio description to detail voice style, tone, and environment. This allows for fine-tuned customization of the audio output.
Yes, the model is ideal for commercial applications such as marketing videos, virtual presenters, and branded content. The generated videos can be used in a variety of professional settings.
Pricing varies by model and is based on a pay-as-you-go credit system. This offers flexibility and scalability, so you only pay for the resources you use.
Yes, you can use the negative prompt fields to specify attributes you want the model to avoid, such as jitter, blur, distortion for video, or robotic, echo, or muffled for audio.
Credit costs for Ovi Image-to-Video depend on generation parameters like inference steps and video length, but typically range from 15-30 credits per video. The model's 30-step default setting balances quality and speed efficiently. Higher inference steps (up to 50) produce smoother animations but increase both generation time and credit cost. Compared to models like
Kling AI Avatar Pro, which may cost more per generation due to higher resolution output, Ovi offers competitive pricing for standard talking-head content. Since JAI Portal uses pay-as-you-go credits with no subscription, you can test different settings and only pay for successful generations. Monitor your credit usage in your account dashboard to optimize your budget across multiple projects.
Yes, all content generated with paid credits on JAI Portal, including Ovi Image-to-Video output, comes with full commercial-use rights. You can use the videos in advertisements, client projects, social media campaigns, product demos, and any other commercial application without additional licensing fees. This makes Ovi ideal for agencies, marketers, and freelancers who need to deliver professional talking-avatar content to clients. Just ensure your input image has appropriate usage rights—if you're animating a photo of a person, you should have permission or rights to that image. The AI-generated animation and audio are yours to use commercially once created with credits.
Ovi Image-to-Video generates videos at standard definition optimized for web and social media use, typically in MP4 format with H.264 encoding. The exact resolution depends on your input image dimensions, but output is generally suitable for 720p-1080p display. If you need higher resolution for large-screen presentations or broadcast, you can upscale the output using dedicated video enhancement models available on JAI Portal. For native high-resolution avatar generation, consider
Kling AI Avatar v2 Standard which supports larger output dimensions. The MP4 format ensures broad compatibility with video editors, social platforms, and presentation software, making post-production integration straightforward.
Ovi Image-to-Video's speech synthesis is primarily optimized for English, but the model can handle various accents and speaking styles through detailed
descriptions. While you can't directly specify non-English languages in the current version, you can describe accent characteristics like "British accent, received pronunciation" or "American Southern drawl, warm tone" in your audio caption tags. For multilingual avatar projects, you might generate the video with English as a placeholder, then replace the audio track in post-production with professionally recorded foreign-language audio. Alternatively, explore Bytedance Omnihuman v1.5 for broader language support if your project requires native non-English speech generation with lip-sync.
If you encounter unnatural facial movements, first verify your input image meets quality standards: clear face, good lighting, neutral expression, front-facing angle. Blurry or low-resolution images often produce jerky animations. For audio sync issues, simplify your speech prompt—remove complex punctuation, keep sentences short, and avoid run-on phrases. The model performs best with natural speech patterns and clear pauses. Add specific problem descriptions to your negative prompts: "stiff jaw, frozen expression" for video or "delayed sync, audio lag" for audio issues. If problems persist after optimizing your input, try
Stable Avatar as an alternative that may handle your specific image characteristics better. Generation time can also affect quality—if the platform is busy, retry during off-peak hours for potentially better results.
