Choosing a model and length

Start with what the clip must do. Length, resolution and sound decide the model. Length also decides how many credits a video costs.

How credits work

You pay in credits for each video. The price depends on the model, the length and settings such as resolution, and a longer clip costs more.

Your free videos use Senfers 1.0. See pricing for credit packs, and the model pages for the current price per clip.

Taken from the model pages. Open one for the price and example prompts.

Start from what the clip needs:

A quick first test: Senfers 1.0. Your free videos use it.
A product photo to animate: Senfers 1.0, Kling 3.0, Seedance 2.5 or Wan 3.0.
Sound in the video: MiniMax H3 includes it. Seedance 2.5 and Wan 3.0 have it as an option, and Kling 3.0 Standard and Pro have sound too.
Clips longer than 15 seconds: Seedance 2.5 or Wan 3.0, up to 30 seconds.
A clip in 1080p: Wan 3.0, or Kling 3.0 Fast.
A first and last frame: Senfers 1.0, Kling 3.0 Standard and Pro, Seedance 2.5 or Wan 3.0.

A short clip is the cheapest way to test an idea. Start at the shortest length that shows the action, then go longer if the clip needs it.

Senfers 1.0 goes up to 10 seconds, which fits short ads and hooks. For a longer story, plan the scenes as separate clips.

Test the idea on one model at a short length. Move to another model only when the clip needs something the first one cannot do.
