How Start Frame + End Frame Video Works
Step 1
Upload start frame
Choose a 16:9 first-frame image that defines how the clip opens.
Step 2
Upload end frame
Choose a 16:9 last-frame image that defines how the clip should finish.
Step 3
Write a motion prompt
Describe action, camera path, lighting, and the transition between both frames.
Step 4
Generate the video
MiniMax H3 interpolates motion between the start and end frames into a short AI video.
What Is MiniMax H3?
MiniMax H3 is an AI video generator workflow on the Grok AI platform for image-to-video creation with first-frame and last-frame control. Instead of animating a single still image, you define both the opening shot and the closing shot, then let MiniMax H3 generate the in-between motion.
This start and end frame approach is useful when you need smoother transitions, stronger character consistency, and more cinematic camera movement across a short clip.
Best Uses for MiniMax H3 Video Generation
Cinematic scene transitions
Move from one composed shot to another with controlled camera motion and lighting continuity.
Character animation
Keep the same subject identity while changing pose, expression, or position across the clip.
Product videos
Reveal a product from a hero angle to a detail shot with polished, ad-ready movement.
Social media clips
Create short start-to-end videos for Reels, Shorts, and TikTok-style storytelling.

FAQ
What is MiniMax H3?
MiniMax H3 is an AI video generator on the Grok AI platform focused on start frame and end frame image-to-video creation.
What is start frame + end frame video generation?
You upload a first-frame image and a last-frame image, then MiniMax H3 generates the motion that connects them into one video.
How is this different from regular image to video?
Standard image to video usually starts from one still. Start and end frame video lets you control both the opening and closing shots.
Can MiniMax H3 keep character consistency?
That is one of the main reasons to use first-frame and last-frame control: the subject can stay visually consistent while the scene changes.
Is this the official MiniMax website?
No. This is a MiniMax H3 video generator page on the Grok AI platform, not an official MiniMax company site.
Do I need both a start frame and an end frame?
Yes. This workflow is built around two keyframes so the model can interpolate a smoother, more directed transition.
What kind of videos can I create?
Short cinematic scenes, product reveals, character animations, scene transitions, and social media clips.
What image size should I upload?
Upload 16:9 landscape images for both the start frame and the end frame. This workflow does not use a separate aspect-ratio picker.
How long can the generated video be?
You can choose a clip length from 3 to 10 seconds. The start and end frames stay the same; only the generated motion duration changes.
