Welcome to D7 Studio - Generation Guide
This guide helps you choose the right generation mode and write a useful prompt. It does not present specific brands or technologies: it explains the logic of each mode available on the platform.
The essential idea :Your prompt should add only the information that your text, image, or video does not already provide.
How to use this guide
- If you are new: start with "Choose the right mode," then read only the section that matches your input.
- If you already know the mode: use the quick formula, copy-ready example, and checklist in that section.
- If you need a very precise result: review the limitations and common mistakes before generating.
Prompt language
You can write your prompt in English or another language. English often provides the greatest precision for camera and cinematic terminology, but clear descriptions in other languages work very well when the structure is simple.

The foundations of a good video prompt
July 29, 2026
A good prompt describes a shot that could realistically be filmed. It states what is visible and what moves, without piling up abstract intentions or contradictory constraints.
The six useful elements
| Element | Simple question | Example |
|---|---|---|
| Framing | What does the camera see? | Wide shot, medium shot, close-up, aerial view. |
| Subject | Who or what is filmed? | A woman, a vehicle, a product, a landscape. |
| Action | What happens? | Walks, turns around, opens a door, places an object. |
| Camera | How does the camera move? | Push-in, lateral tracking, locked camera. |
| Lighting | How is the scene lit? | Warm morning light, cool neon, backlighting. |
| Mood | What feeling is visible or audible? | Calm, tension, understated luxury, café ambience. |
Match complexity to duration
| Duration | Recommended scope | Example progression |
|---|---|---|
| 2 to 4 s | One action and one camera move. | The product rotates slowly during a gentle push-in. |
| 5 to 8 s | One main action and a brief reaction. | The character enters, places the product, and looks at the camera. |
| 9 to 12 s | Two coherent stages or one reveal. | The camera follows the subject, then reveals the setting. |
| Over 12 s | Keep a simple progression; split complex ideas. | Create several shots or use video extension. |
What belongs in the prompt
- Useful actions, movement, lighting, mood, and sound.
- The role of each reference when several assets are uploaded.
- What must be preserved when a video is transformed.
- The exact dialogue in quotation marks when audio is available.
What belongs in the settings
- Duration, aspect ratio, resolution, and quality when the interface provides a dedicated field.
- The number of outputs, cost options, and selected mode.
- Uploaded files and their order.
Tip.Do not write a long list of negative constraints. Describe the intended result positively and add only the essential elements to preserve.
