Tips

  • Best value for character animation. Wan handles human and cartoon motion well at a fraction of Kling/Seedance cost.
  • Preview variant is good for quick iteration at even lower cost.
  • Combine with Soul for consistent character generation — use Soul to create the character image, then Wan to animate.
  • Audio input can drive motion — provide an audio_url in provider options for music-driven animation.

Kling V3

Higher quality, more expensive. Best for hero content.

Minimax

Similar price point, different motion characteristics.

LTX

Even cheaper at 50 credits. Fastest generation.
