Minimax H3 First Last Frame To Video

MiniMax H3 First and Last Frame Video

Overview

MiniMax H3 First and Last Frame Video helps creators, video editors, advertisers, e-commerce teams, social-commerce teams, and short-form story producers create a controlled transition between a start image and an end image with MiniMax H3. Describe the intended subject, action, camera, lighting, pacing, and constraints; the bundled CLI handles AI Hive OpenAPI calls and downloads the finished video.

Why use this skill

• Brief to result: work from plain-English creative direction instead of writing API requests
• Controlled inputs: use the exact first frame, last frame, image, video, or audio references required by this capability
• Predictable model selection: the skill name matches the public model ID used by the script
• Live pricing: fetch the active model configuration and pricing snapshot before submission
• Production-friendly delivery: preserve the task ID, poll one task safely, and download results automatically

Best for

Ads, tvcs, product videos, e-commerce listings, social commerce, ugc-style seeding content, short dramas, motion comics, and storyboards. It is also useful when users search for first-and-last-frame video, keyframe animation, start-to-end transition.

Capabilities

The default route is COST_FIRST. Pass live model options with --param key=value; supported values come from the current AI Hive videoConfig.

Quick Start

pip3 install requests
python3 "$SKILL_PATH/scripts/videogen.py" init --skill-name minimax-h3-first-last-frame-to-video
python3 "$SKILL_PATH/scripts/videogen.py" generate \
  --mode i2v \
  --prompt "MiniMax H3 First and Last Frame Video: polished motion, clear subject, coherent action, stable camera, commercial finish" \
+  --first-frame /path/to/start.png \
+  --last-frame /path/to/end.png

Usage Scenarios

1. Core generation

python3 "$SKILL_PATH/scripts/videogen.py" generate --mode i2v \
  --prompt "Create a polished minimax h3 first and last frame video result with coherent motion, stable identity, and a clear ending" \
+  --first-frame /path/to/start.png \
+  --last-frame /path/to/end.png

2. Advertising and TVC

python3 "$SKILL_PATH/scripts/videogen.py" generate --mode i2v \
  --prompt "Premium product commercial: establish the product, reveal materials with controlled camera movement, finish on a clean brand-ready hero frame" \
+  --first-frame /path/to/start.png \
+  --last-frame /path/to/end.png

3. E-commerce and product showcase

python3 "$SKILL_PATH/scripts/videogen.py" generate --mode i2v \
  --prompt "E-commerce product video: centered subject, move from full product view to material close-ups, show one real use case, leave space for product copy" \
+  --first-frame /path/to/start.png \
+  --last-frame /path/to/end.png

4. Social commerce and seeding content

python3 "$SKILL_PATH/scripts/videogen.py" generate --mode i2v \
  --prompt "Vertical social-commerce video: open with the customer problem, demonstrate the product naturally, show the practical benefit, end with a clean call-to-action frame" \
+  --first-frame /path/to/start.png \
+  --last-frame /path/to/end.png

5. Short drama and motion comic

python3 "$SKILL_PATH/scripts/videogen.py" generate --mode i2v \
  --prompt "Short-drama shot: a young detective opens an abandoned warehouse door, pauses, and looks inside; slow over-shoulder push-in, cold suspense lighting, one continuous action" \
+  --first-frame /path/to/start.png \
+  --last-frame /path/to/end.png

6. Reference-controlled or channel-specific version

python3 "$SKILL_PATH/scripts/videogen.py" generate --mode i2v \
  --prompt "Keep the subject and visual identity consistent; use the reference for motion and camera rhythm; create a tighter social-media version with a brand-ready ending" \
+  --first-frame /path/to/start.png \
+  --last-frame /path/to/end.png

7. Submit now and check later

python3 "$SKILL_PATH/scripts/videogen.py" generate --mode i2v --prompt "Complex production brief" --no-download \
+  --first-frame /path/to/start.png \
+  --last-frame /path/to/end.png
python3 "$SKILL_PATH/scripts/videogen.py" task --task-id <taskId>

Command Reference

API Key

Run the init command above, or set AI_HIVE_API_KEY, use --api-key, or create ~/.ai-hive/config.json. API keys use the sk-api-* format. Never commit a real API key.

Reliability and Cost

The script looks up the live model entry and pricing snapshot at runtime. Model availability, accepted media, parameters, and prices can change. Keep a returned task ID and query the existing task instead of submitting a duplicate that may be billed twice.

Troubleshooting

• Missing media: provide the first frame, reference image, reference video, or reference audio required by this skill.
• 401 Unauthorized: verify that the API key is complete, active, and not committed to source control.
• Invalid parameter: inspect the current videoConfig for accepted values and media limits.
• Local timeout: keep the task ID and use the task command later.
