- Input

- Typical cost
- 720p/5s drafts start around 5 credits

Start with a 720p/5s draft, then raise quality or length after the direction works.
| Decision point | Text to video | Image to video |
|---|---|---|
| Best starting point | Only a creative brief or script exists | A product, character, or poster image already exists |
| Control focus | Camera, pacing, setting, and action | Subject consistency, material, composition, and style |
| Recommended next step | Generate prompt variants, then save the strongest direction | Upload a clear reference image, then keep motion constrained |
Do text-to-video jobs need an uploaded image?
No. You can start with text only; switch to image-to-video or multimodal references when you need fixed subjects or style.
How long should the prompt be?
Use 1 to 3 sentences covering subject, action, setting, camera, lighting, and format while avoiding conflicting style instructions.
Can I test direction at lower cost first?
Yes. Start with a 720p/5s or lighter draft, then upgrade quality or duration once the direction works.
