Best for: Quick drafts and testing ideas.

The Standard tier of Kling 3.0 delivers solid results at a lower cost. It supports durations up to 15 seconds and produces 1080p output. If you're iterating on ideas and don't need the highest quality, this is your go-to.

  • 8 credits per second — most affordable Kling option
  • Native audio generation supported
  • Good motion consistency
  • Durations: 3s, 5s, 10s, 15s

Kling 3.0 Pro

Best for: Production-quality videos with character consistency.

Kling Pro is the default model on Veblo.ai for good reason. It delivers the best balance of quality, consistency, and features. It supports character references for keeping faces consistent across scenes, making it ideal for storytelling and Cinema Mode.

  • 12 credits per second
  • 4K resolution output
  • Character consistency via reference photos
  • Native audio generation
  • Best for: product videos, social media, marketing content

Veo 3.1 Fast

Best for: High-quality results when you need speed.

Google's Veo 3.1 Fast is a strong alternative to Kling. It generates high-quality video quickly and includes native audio. The trade-off: max 8 seconds and no character reference support.

Veo 3.1 (Premium)

  • 40 credits per second — premium pricing
  • 4K resolution
  • Best-in-class realism and physics
  • Stunning native audio
  • Durations: 4s, 8s

Wan 2.6

Best for: Budget-friendly testing and high volume.

Alibaba's Wan 2.6 is the most affordable option. Quality is a step below Kling Pro, but at 6 credits per second it's hard to beat for rapid prototyping or generating large batches of content.

  • 6 credits per second — cheapest option
  • 2K resolution
  • No native audio (pair with Text to Voice)
  • Durations: 5s, 10s

FAQ

Can I switch models mid-project?

Yes. Each block in the Veblo Planner has its own model selector. You can use Wan 2.6 for draft clips and re-generate the final version with Kling Pro or Veo 3.1.

Does the model affect credit cost?

Yes. Credits are calculated as: duration (seconds) × credits per second. The model selector shows the per-second rate so you always know the cost before generating.

Which model has the best audio?

Veo 3.1 produces the most realistic ambient audio. Kling Pro is a close second. Wan 2.6 does not generate audio — you can add voiceover separately using the Text to Voice block.

Is Seedance 2.0 coming?

Yes! ByteDance's Seedance 2.0 model will be added to Veblo.ai as soon as the API becomes available. It's already listed in the model selector as "coming soon".
