AI Video Generator
Describe a shot or start from an image, pick a model and get an MP4.
Compare the video models
Four models, one form. MiniMax H3 is the fastest and cheapest; prices are for each model’s default clip.
From a prompt to an MP4 clip
- Step 1
Describe the shot
Say what moves and how the camera follows it, for example "a knight walks through a burning village, slow tracking shot".
- Step 2
Add a first frame
Optional: attach a character, a scene or a screenshot of your game and the clip opens on it.
- Step 3
Generate and download
See the price before it starts. The MP4 lands here and in My assets, ready for a cutscene, a menu or a trailer.
AI video questions
Which AI video models can I use?
MiniMax H3 Max Turbo, the default and the fastest and cheapest, plus Kling 4, Veo 3.1 Fast and Seedance 2.5. Kling and Seedance give the smoothest, most cinematic motion, and every model makes sound.
Can I turn an image into a video?
Yes. Attach a first frame, such as a character, a scene or a screenshot of your game, and the clip opens on it. The image sets the clip’s shape, so you only pick an aspect ratio without one.
Do the clips have sound?
Yes, every model generates sound that matches the clip. MiniMax H3 and Kling 4 always include it. Veo 3.1 Fast and Seedance 2.5 let you turn it off under Clip options, and Veo costs less without sound.
How long can a clip be?
Up to 10 seconds. MiniMax H3 makes 1 to 10 seconds, Kling 4 makes 3 to 10, Seedance 2.5 makes 4 to 10, and Veo 3.1 Fast makes 4, 6 or 8.
How much does it cost?
Generating uses Rosebud credits, and you see the price before a clip starts. MiniMax H3 is the cheapest and Seedance 2.5 the most expensive; longer and higher-quality clips cost more, and Veo is cheaper without sound. Free accounts get credits every week.
What format are the clips?
MP4, which plays in browsers and imports into Unity, Godot, Unreal and video editors. Every clip is also saved to My assets.
Can I use the clips in my game?
Yes, in games on Rosebud or anywhere else: cutscenes, menu backgrounds, trailers and social posts. Paid plans include commercial rights.
