V1 Pro vs V1 Lite (Image‑to‑Video)

V1 Pro — Higher control

Pick a resolution (480p/720p/1080p), set 3–12s duration, and optionally fix the camera. Designed for quality marketing shots.

  • • Inputs: prompt, image_url, resolution, duration, camera_fixed
  • • Credits per second by resolution (6/10/16)

V1 Lite — Fast iteration

A streamlined flow for quick concepts. Set 3–12s duration; pricing starts at 20 credits (3s) and increases by 5 per extra second.

  • • Inputs: prompt, image_url, duration, resolution
  • • Credits: 3s=20, then +5 per extra second
Try Seedream Studio

How it works

  1. Write a clear prompt (use the Enhance button for better motion and detail).
  2. For video, paste an image URL and choose V1 Pro or V1 Lite with duration and resolution.
  3. Submit. We process async via webhook + polling; results render inline when ready.

FAQ

Do I need to host the input image?

Yes, provide a public https URL (png/jpg/webp ≤10 MB). For privacy‑sensitive assets, use temporary links.

Can I disable the safety checker?

Image Studio enables it by default; via API you can toggle with enable_safety_checker.

What happens on failures?

Failures are marked in the app and credits are automatically refunded to your balance.
