# Pixverse > Use the latest pixverse v5.6 model to turn your texts and images into amazing videos. ## Overview - **Endpoint**: `https://fal.run/fal-ai/pixverse/v5.6/transition` - **Model ID**: `fal-ai/pixverse/v5.6/transition` - **Category**: image-to-video - **Kind**: inference **Tags**: image-to-video ## Pricing For a 5s video without audio, your request will cost $0.35 for 360p and 540p, $0.45 for 720p, and $0.75 for 1080p. Enabling audio adds $0.45 for 360p/540p/720p, and $0.75 for 1080p. For 8-second videos, costs are 2x the 5-second base; for 10-second videos, costs are 2.2x the 5-second base for 360p/540p and 720p (1080p not supported for 10s).

const result = await fal.subscribe("fal-ai/pixverse/v5.6/transition", { input: { prompt: "Scene slowly transition into cat swimming under water", first_image_url: "https://v3.fal.media/files/zebra/owQh2DAzk8UU7J02nr5RY_Co2P4boLv6meIZ5t9gKvL_8685da151df343ab8bf82165c928e2a5.jpg" }, logs: true, onQueueUpdate: (update) => { if (update.status === "IN_PROGRESS") { update.logs.map((log) => log.message).forEach(console.log); } }, }); console.log(result.data); console.log(result.requestId); ``` ## Additional Resources ### Documentation - [Model Playground](https://fal.ai/models/fal-ai/pixverse/v5.6/transition) - [API Documentation](https://fal.ai/models/fal-ai/pixverse/v5.6/transition/api) - [OpenAPI Schema](https://fal.ai/api/openapi/queue/openapi.json?endpoint_id=fal-ai/pixverse/v5.6/transition) ### fal.ai Platform - [Platform Documentation](https://docs.fal.ai) - [Python Client](https://docs.fal.ai/clients/python) - [JavaScript Client](https://docs.fal.ai/clients/javascript)
