When to choose Kling

• Character and people shots where you want readable motion and expressions.
• Image-to-video from an approved still, so composition and styling stay locked.
• Higher-resolution deliverables when the 4K variant is available for your settings.
• Short product, fashion and lifestyle clips cut into social edits.

When to choose Seedance

• Reference-to-video: keep a character, product or outfit consistent by giving reference images.
• Fast, low-cost drafts on the lighter tiers while you search for the idea.
• Multi-shot social content where several clips need to feel like one campaign.
• Image-to-video for stylised and illustrated looks.

How to run a fair comparison

1. Use the same prompt, the same start image and the same aspect ratio on both models.
2. Match duration and resolution where both models support them; the tables above show the overlap.
3. Generate two or three takes per model. One take of each says more about luck than about the model.
4. Judge at full size on the screen it is made for: motion quality, subject stability, prompt adherence and artefacts.
5. Compare cost per usable take, not cost per generation.
