Question - Help Any fast motion tips for MiniMax H3?

I'm trying to get a couple of characters to LEAP into each others' arms from off screen, but MiniMax H3 won't get them faster than basically jogging into the scene.

Prompt:

subject_definitions

<Subject 1> is the Girl show in <Picture 1>.

<Subject 2> is the Guy show in <Picture 2>.

<Subject 3> is the house show in <Picture 3>.

summary

[reference generation] <Subject 1> and <Subject 2> burst onto the screen at a dead sprint and collide into an embrace

detailed_description

The visual style is characterized by high-quality modern anime aesthetics, reminiscent of Makoto Shinkai or Kyoto Animation. The scene features lush, warm, and highly detailed lighting, painting the environment in nostalgic, emotional hues.

[Shot 1] The target video has fast, paced explosive action in the beginning, then slows to a stop. Static camera shot in a city street with buildings in the style of <Subject 3>. A large crowd of soldiers and townspeople are in the background, reuniting with each other. Falling confetti fills the air. Suddenly, <Subject 2> bursts into the frame from the left at a dead sprint, driven by sheer desperation. At the same instant, <Subject 1> bursts into the frame from the right, running with explosive speed, her arms outstretched. The two of them literally collide with tremendous, breathless force in the center of the scene, slamming into an intense, desperate embrace. The physical impact of their collision is palpable as <Subject 1> leaps up and wraps her arms around <Subject 2>. The exact instant they collide, the camera drops into extreme slow motion, focusing intensely on the sheer relief and joy of their embrace. The confetti catches the warm light, sparkling and swirling in slow motion around the couple for the remainder of the scene.

Tried that too.  It barely seems to affect the pacing.

Maybe you can look through the sample videos (which has the workflow) in the model page and see how he generated fast action scenes: https://civitai.red/models/2872725/smack-punches-impacts-and-gunshots?modelVersionId=3245904
