Create polished 2K videos with MiniMax H3 from prompts and references.
Use MiniMax H3 for text-to-video, first and last frame animation, or multimodal reference generation. Choose a 4–15 second duration, aspect ratio, and optional AIGC watermark before rendering.
CharaVox brings MiniMax H3 video generation into the same studio as voice, music, and stories. Start with a written scene, anchor motion with a first or last frame, or combine visual and audio references when a prompt alone is not precise enough.
The workspace is designed for creator handoff rather than one-off demos: it estimates credits before submission, keeps task state across refreshes, stores successful MP4 files privately, and provides playback, download, failure details, and generation history.
Capabilities
Text-to-Video
Describe the subject, camera movement, lighting, and action, then generate a 4–15 second 2K clip in a fixed aspect ratio.
First and Last Frames
Upload a first frame, a last frame, or both to guide composition and motion while MiniMax H3 adapts the output ratio to the source.
Multimodal References
Guide a scene with up to nine images, three videos, and three audio clips, with no more than twelve reference files in one task.
Private Generation History
Track queued and running jobs, preview completed MP4 videos, download the result, and review clear failure details from one workspace.
Why creators choose it
Move from script, voice, and music into video without leaving the CharaVox studio.
Choose text, frame, or multimodal reference workflows instead of forcing every idea into one input format.
See the maximum credit reservation before submission and pay only after a successful result is finalized.
Keep uploads and finished videos in private storage with plan-based retention and signed playback links.
Use cases
Frequently asked questions
The first release uses MiniMax-H3 at 2K resolution. The model and resolution are fixed so prompts, credit estimates, and output behavior stay consistent across the Studio workflow.
Each output can be set from 4 to 15 seconds. Text-to-video supports fixed aspect ratios, while frame-guided generation automatically adapts the ratio to the uploaded first or last frame.
Multimodal reference mode accepts up to nine images, three videos, and three audio clips, with a total limit of twelve files. Audio must be paired with at least one image or video reference.
Yes. You can upload supported media directly to private storage or provide an HTTPS URL. The server validates file type, size, ownership, and network safety before MiniMax receives the reference.
CharaVox reserves the maximum estimate when a task is created, then settles against MiniMax usage only after the video succeeds. Unused reserved credits are released, and failed tasks are not charged.
Video generation is available to Creator and Pro subscribers. The public page can be viewed without signing in, but a supported paid plan is required before a generation task can be submitted.
