MiniMax H3 Max: Generate AI Videos in Just 22 Seconds

Create your own AI videos with MiniMax H3 Max: https://yb.digital/art
MiniMax H3 Max is incredibly fast! In this video, I test its video generation speed using four character references to create a 15-second vertical AI video for social media.
Using OpenArt, I select MiniMax H3 Max, add my characters and script, and generate a 480p video. The first generation takes around 30 seconds, demonstrating how quickly the model can produce a scene with multiple characters.
But speed isn't everything. The first video mixes up two female characters, assigning the wrong character to the scene. I then modify the video prompt, correct the character references, and generate it again.
The second attempt takes just **22 seconds**. This time, the characters are correctly assigned, showing how important accurate character references are when generating AI videos.
In this test, I explore:
* MiniMax H3 Max video generation speed
* Text-to-Video and character reference workflows
* Generating 15-second vertical videos at 480p
* Correcting character mix-ups with better references
* How quickly you can regenerate a video after fixing a prompt
The key takeaway: correcting the prompt can take longer than generating the video itself.
Try MiniMax H3 Max with OpenArt and experiment with your own AI videos.
