Can MiniMax H3 Generate Video with Audio?

Overview

Yes. Native stereo audio is one of MiniMax H3’s headline features: it generates sound together with the video in a single pass, rather than needing a separate text-to-speech or scoring step. The audio can include dialogue, sound effects, and ambient room tone.

That changes a typical workflow. For many clips — a quick ad, a social spot, a mood test — you get picture and synchronized sound from one generation, which removes a whole pipeline stage. Describe the audio in your prompt as deliberately as the visuals: name the ambient soundscape, any specific sound events, and the dialogue tone if speech is involved.

Set expectations by content. Ambient sound and simple audio tend to be reliable; precise lip-synced dialogue over a longer clip is the hardest case and can drift, so test your specific lines before depending on them. Keeping clips short helps sync hold.

Native audio can replace a separate TTS-and-lip-sync stage when it holds up, but validate quality on your own hardest lines before retiring a fallback. This capability runs through the current hosted API.
