How many MiniMax H3 keyframes can I upload here?
The current First and Last Frame mode accepts two controlling keyframes: one opening image and one ending image. For more storyboard points, generate a sequence of connected shots.
MiniMax H3 Keyframes
Upload a first frame and a last frame, then describe the action, camera movement, and pacing that should connect them. This MiniMax H3 keyframe workflow controls two visual endpoints while the model generates the continuous transition between them.

MiniMax H3 Keyframes Example: Plan a Continuous Transition
This unmodified H3 Max output begins from a fixed wedding frame and develops one continuous action toward a deliberate ending beat. It demonstrates the motion, camera, continuity, and endpoint language to use when directing a first-and-last-frame transition.
What MiniMax H3 Keyframes Control Online
The current generator controls two keyframes: the opening image and the closing image. The prompt directs how the shot travels between those endpoints.
First Frame
Upload the exact opening composition. Use a clear subject, readable pose, intentional framing, and enough background detail to support motion.
Last Frame
Upload the intended destination of the shot. Keep the subject identity, aspect ratio, visual style, and scene logic compatible with the first frame.
Transition Prompt
Describe the action and camera path in time order, then state the continuity details that must remain stable from the opening to the ending.
How to Use MiniMax H3 Keyframes
Start in First and Last Frame mode, prepare compatible endpoints, and direct one achievable shot between them.
01
Upload the Starting Frame
Choose an image that clearly establishes the subject, environment, camera angle, lighting, and opening pose.
02
Upload the Ending Frame
Add the target composition in the last-frame slot. Match the aspect ratio and preserve the visual details that should remain consistent.
03
Describe the Transition
Write what changes first, next, and last. Include subject motion, camera movement, environmental motion, sound, and the intended arrival at the final frame.
04
Generate and Refine
Review endpoint similarity, motion continuity, identity, and pacing. Change one major input or direction at a time when creating the next version.
Plan Multiple Shots With MiniMax H3 Keyframes
The online tool accepts a first and last frame for one generation. For a multi-keyframe sequence, split the storyboard into connected shots and reuse each endpoint deliberately.
Divide the Storyboard
Turn a longer idea into short shots, each with one clear action arc and two endpoint frames instead of forcing several scene changes into one clip.
Share Boundary Frames
Use the last frame of one shot as the first frame of the next when you want visual continuity across the edit.
Assemble the Sequence
Generate each transition separately, select the strongest takes, then join them in an editor for precise timing, sound, and shot order.
MiniMax H3 Keyframes for Controlled Video Ideas
Two visual endpoints are most useful when the destination matters as much as the opening action.
Transformations
Define the before and after states of a character, object, material, season, or environment while directing the change between them.
Camera Transitions
Plan a push-in, orbit, crane, reveal, or match move that begins and ends on intentional compositions.
Storyboard Previsualization
Connect two storyboard panels to explore blocking, pacing, screen direction, and whether the planned shot reads clearly in motion.
Product Reveals
Start with a concealed or wide product view and finish on a deliberate hero angle while keeping shape, materials, and branding stable.
Pose-to-Pose Motion
Guide a character from one readable pose to another with a prompt that explains the physical action and camera behavior.
Multi-Shot Sequences
Build a longer piece as several first-and-last-frame generations with shared boundary images and consistent visual direction.
MiniMax H3 Keyframes Workflow Questions
Understand the current first-and-last-frame controls, input preparation, prompting, and storyboard approach.
Does MiniMax H3 reproduce both keyframes exactly?
The images strongly guide the endpoints, but exact pixel-level reproduction is not guaranteed. Compatible framing, identity, lighting, and scene structure usually create a more coherent transition.
What makes a good first-and-last-frame pair?
Use the same aspect ratio and subject design, keep the change physically achievable, and avoid contradictory viewpoints, lighting, object counts, or environments unless the transition explains them.
How should I prompt a MiniMax H3 keyframe transition?
Describe the opening action, intermediate movement, camera path, and final arrival in chronological order. Add concise continuity constraints for identity, wardrobe, props, style, and location.
Can I create MiniMax H3 multi keyframes in one video?
Not as separate uploaded control points in the current online form. Break the storyboard into adjacent first-and-last-frame shots, reuse boundary frames, and assemble the clips afterward.
Can I use only a first frame or switch to other modes?
Yes. The generator also supports text-to-video, first-frame generation, image references, and multimodal references. First and Last Frame appears first because it is the focus of this page.
