VIW AI - Seedream 4K Cinematic Video

Can Seedream 4.5 preserve facial features and expressions when I edit a reference image?

Yes. Seedream 4.5 is built to maintain facial features, lighting, and color tones across edits, which is one of its core strengths for e-commerce and portrait work. This reference consistency extends to material transformations (changing metal to glass or water, for example) and area-specific edits, so you can modify parts of an image without losing the original character of a subject.

How does Seedream handle text in posters and designs when I ask for changes?

Seedream 4.5 offers designer-level text localization and can translate text while preserving layouts, which makes it useful for multilingual campaigns and poster design. The model is trained to keep typography clear and readable, though you should verify the output matches your exact requirements before using it in production.

What file size and batch limits should I know about when uploading reference images?

Seedream accepts images up to 10MB per file and processes up to 10 images per batch. If you hit these constraints, you'll need to split larger jobs into multiple uploads or compress reference files before sending them to the model.

How do I use the free credits as a new user, and what happens if I run out?

VIW AI gives new users free credits to start. Once those are spent, you can buy additional credits or subscribe for ongoing access. The platform auto-refunds failed jobs, so you won't lose credits to generation errors.
