Instead, it gives you a well-structured starting point that you can quickly review, tweak, and customize before sending it to MiniMax.Simple idea → Enhanced prompt → Your edits → Video generation💡 Tip: The generated prompt is a starting point. Read through it and adjust the details, actions, camera movement, timing, and style to match your exact vision.Feel free to use, modify, and integrate this workflow into your own projects. If you create something with it or improve the prompting method, share your results and prompting tips in the comments so the community can keep improving it!If you use this workflow in your own workflow pack, a quick mention would be greatly appreciated. ❤️
