### Input Schema

The API accepts the following input parameters:

  Prompt
  Enter desired video effects like 'smooth zoom'. For creativity, try 'vibrant kaleidoscope'.
  - Default: `"A beloved community figure moves through a 1920s street carnival, warmly interacting with attendees. Vintage cars, dancing performers, and striped carnival tents fill the scene. Camera follows closely in a handheld cinematic style, capturing intimate smiles and connections, shallow depth of field, 4K UHD, golden warm lighting."`
