MiniMax H3

MiniMax H3 is a general-purpose multimodal video model launched by MiniMax. It can interpret text and reference media, plan camera movements, and generate videos with synchronized dialogue, sound effects, and ambient audio. Compared with its predecessor, it adds native synchronized audio, richer multimodal reference control, longer instruction support, higher native resolution capability, and open weights. It is designed to help users easily and quickly generate high-quality videos from text or images, and it suits any scenario that requires video content. On access, users can try it for free, and new accounts have 20 credits, which can be used for two default 480P, five-second video generations.

- Generate short videos from text or first and last frames

- Add synchronized dialogue, sound effects, and ambient audio

- Plan camera movement through text and reference media

- Output at 480P, 720P, or 1080P depending on your needs

- Creators who need short videos with built-in synchronized audio

- Users exploring multimodal text and frame based generation

- Anyone testing video generation with free starting credits

The 20 free credits only cover a couple of short generations, so the free tier is for evaluation rather than sustained production. Longer or higher-resolution videos will consume more credits, so costs scale with use. Audio and motion quality still benefit from human review, since generated dialogue and ambient sound may need adjustment. Credit rules and free allowances can change, so confirm the current details before you rely on them. For best results, start with a small test file and review the output carefully before working on anything important.
