•required

Text describing the prompt or requested edit.

aspect_ratio default 16:9

Aspect ratio for the output.

default 848

Longer-edge pixel setting: editing uses it as a size ceiling for source/reference media, while generation uses it to set output size.

default 81

Frame count, adjusted internally to the form 4k+1.

default 16

Frame rate of the output, in frames per second.

Advanced negative_prompt · acceleration · num_inference_steps · seed · enable_prompt_expansion · enable_safety_checker

Negative prompt, using Wan2.2's standard negative prompt when unspecified.

acceleration default none

Degree of acceleration to apply.

default 30

Count of denoising steps to perform.

Seed that enables reproducible results; chosen randomly if omitted.

About Bernini-R Text to Video

Text-only member of the Bernini-R family: write a `prompt` and choose an `aspect_ratio` of 16:9, 9:16 or 1:1. `num_frames` runs from 5 to 121, `frames_per_second` from 4 to 30 and `num_inference_steps` from 1 to 50. `max_image_size` sets the long edge between 256 and 1280. Optional `negative_prompt` and prompt expansion.
