Short answer: Video settings affect generation time, visual quality, model availability, and credit cost.
Steps
Choose a duration supported by your selected model.
Choose a resolution supported by the model and your intended use.
Review the credit estimate.
Start the generation and keep the page open or return to your library later.
Notes
Video generation can take longer than image generation.
Higher resolution and longer clips can require more processing time.
Some models support 480p, 720p, or 1080p, while others expose a smaller set in the app.
Troubleshooting
If processing takes longer than expected, avoid starting duplicate generations immediately.
If a setting is unavailable, switch models or choose another supported option.
