Define the deliverable before choosing parameters and task handling. For images, start with specifications and references; for video, start with submit, poll and save. Receiving a task ID means acceptance, not completed generation.
Prepare inputs and task handling
Section titled “Prepare inputs and task handling”- Choose image specifications — Plan aspect ratio, resolution and output format using the live schema.
- Preflight reference assets — Check permissions, direct URLs and file properties before submitting references.
- Submit, poll and save a video task — Save the task ID, resume polling and download results without forwarding your API key.
Deliver product images and designed assets
Section titled “Deliver product images and designed assets”- Write a product-image brief — Define what must stay faithful to the reference and how the asset will be accepted.
- Inspect GPT Image 2.5 transparent assets — Check alpha and edge quality on the final background, not only the PNG extension.
- Review poster lettering and layout — Check exact text and plan deterministic typesetting when lettering must be precise.
Deliver MiniMax H3 video
Section titled “Deliver MiniMax H3 video”- Plan storyboards and shot continuity — Keep a shot brief and review identity, camera movement and transitions.
- Review dialogue and audio — Check the words, timing and audio in the delivered clip.
- Deliver landscape and portrait variants — Choose cropping or separate composition, then inspect the entire motion path.
Select models, migrate and budget
Section titled “Select models, migrate and budget”- Compare GPT Image 2.5 and Nano Banana 2 controls — Match controls to the deliverable; this is not a measured quality ranking.
- Choose H3 or H3 Max Turbo — Check input modes, duration and resolution for the intended video task.
- Validate a GPT Image 2.5-to-2.6 migration — Keep a static-image baseline and inspect deliverables before changing versions.
- Budget image and video batches — Include attempts and rejected outputs when reconciling accepted-deliverable cost.
Model contracts and related guides
Section titled “Model contracts and related guides”- Nano Banana 2 integration · Model specifications and pricing
- MiniMax H3 integration · Model specifications and pricing
- Common API · LLM tutorials
To analyze an existing video instead of generating one, use the Gemini shot-log tutorial. Image and video input constraints and billing units differ. Check the live model contract, account access and budget before running examples. Keep the original task ID and do not automatically resubmit paid tasks when the outcome is uncertain.
