What language and length limits apply to a video prompt?

Without Higgsfield: Write video prompts in English, since models are trained mostly on English, though Chinese-developed models such as Seedance and Kling sometimes respond better to Chinese for nuanced motion. Earlier, Seedance 2.0 capped prompts at 3000 characters, which made compact Chinese prompts useful (one to two characters a word against five to ten in English); longer prompts now work.

Axis: English within the cap … another language (Chinese) to fit more
