Quickstart

Get started by following our API guide or jump right into the example of using the Gen-4.5 model below:

Node
Python

import RunwayML, { TaskFailedError } from '@runwayml/sdk';

const client = new RunwayML();

try {
  // Create a new text-to-video task using the "gen4.5" model
  const task = await client.imageToVideo
    .create({
      model: 'gen4.5',
      promptText: 'A serene mountain landscape at sunrise with mist rolling through the valleys',
      ratio: '1280:720',
      duration: 5,
    })
    .waitForTaskOutput();

  console.log('Task complete:', task);
  console.log('Video URL:', task.output[0]);
} catch (error) {
  if (error instanceof TaskFailedError) {
    console.error('The video failed to generate.');
    console.error(error.taskDetails);
  } else {
    console.error(error);
  }
}

from runwayml import RunwayML, TaskFailedError

client = RunwayML()

try:
  task = client.image_to_video.create(
    model='gen4.5',
    prompt_text='A serene mountain landscape at sunrise with mist rolling through the valleys',
    ratio='1280:720',
    duration=5,
  ).wait_for_task_output()

  print('Task complete:', task)
  print('Video URL:', task.output[0])
except TaskFailedError as e:
  print('The video failed to generate.')
  print(e.task_details)
