Features

NVIDIA ChronoEdit — Physics-aware Image Editing

ChronoEdit performs edits by reasoning through a short “imagined motion” between the original and the requested change. That temporal reasoning helps keep geometry, lighting, shadows, and contacts consistent in the final image.

Highlights

• Consistency-first edits: pose, lighting, reflections, and shadows stay believable.
• Works with one input image plus a natural-language instruction.
• Reproducible results with seed control; quick iteration for creative teams.
• Production-friendly outputs in JPEG, PNG, or WEBP; optional BASE64 and sync return.

Parameters

• prompt: Describe the change you want, not general style fluff. Example: replace the plastic mug with a clear glass half-filled with tea; keep same angle and morning light.

• image: Source image URL or upload. Use a clean, well-lit photo for best fidelity.

• seed: Integer for determinism. Same prompt + image + seed gives the same result. Use −1 to randomize.

• output_format: jpeg for compact distribution, png for lossless editing, webp for web delivery.

How to Use

1. Upload the source image.
2. Write a concrete prompt that states the target edit and what must be preserved.
3. Set seed if you need reproducibility.
4. Choose output_format.
5. Run and review. If something drifts, tighten the prompt and fix the seed.

Prompting Tips

• Be explicit about conservation: keep camera angle, keep morning sunlight, keep the person’s pose.
• State the edit as a physical change: swap, add, remove, change material, change color.
• If lighting must change, say it clearly; otherwise the model will preserve the original light.
• For faces or text areas, crop tighter to the region before editing for crisper results.

Per run: $0.02

Quality Notes

• Input quality sets the ceiling. Soft, noisy, or heavily compressed sources limit realism.
• For large pose or object changes, iterate with fixed seed and small prompt adjustments.
