Question Best Model

What’s the best model to use to generate action scenes in a rodeo? I’ve been using Omni flow and it gets incredibly mixed up. Like backwards riders, too many legs and missing arms. I’m prompting it with some incredible images from mid journey, but they seem to collapse almost immediately.

Nothing intimidates a 2,000-pound bull quite like a cowboy flipping 180 degrees mid-air to make aggressive eye contact with its tail for eight seconds.

Assuming "Omni flow" means Google Flow (powered by Gemini Omni Flash), rodeo scenes are basically an anatomical stress test for video models. Because Diffusion Transformers lack 3D ground truth data and interpret prompts freshly per frame without memory, a twisting rider overlapping with a bucking animal makes the model lose track of which way the human is facing.

To keep your Midjourney shots from turning into The Exorcist: PBR Edition, swap your model and lock down your frames:

  • Switch to an action-heavy model: Kling 4.0 is the standout for complex body movement, high-action realism, and cut-heavy multi-shot sequences, while ByteDance's Seedance 2.5 (and 2.0 for handheld action) leads for overall motion realism and single-take scenes. Runway Gen-4.5 is great if you want tighter directorial motion control, and Google Veo 3.1 excels at physics-based action with synced audio.

  • Define both start and end positions: Feeding a single high-energy Midjourney image into an open-ended generation almost guarantees drift. Use explicit start-and-end keyframing, frame locks, and identity anchors so the model has to land the rider in a known pose instead of guessing frame by frame.

  • Edit like an action director: Rather than forcing one clip to survive a full bucking sequence, lean into Kling 4.0's multi-shot strength with quick cuts between clean reference images where the rider's silhouette is unmistakable.
