Reference the video in your prompt using `@Video1`. **Features:** - Use a reference video (3-10s) to guide motion and style - Combine with an image for start frame control - Faster generation at slightly lower quality **Use case:** Create videos that follow motion patterns from a reference video while applying your creative prompt. **Duration:** 3-15 seconds **Quality:** Standard mode offers faster generation at slightly lower quality. **Tip:** For text-to-video or image-to-video without a reference video, use the `/ai/video/kling-v3-omni-std` endpoint instead. ## OpenAPI ````yaml post /v1/ai/reference-to-video/kling-v3-omni-std openapi: 3.0.0 info: description: >- The Magnific API is your gateway to a vast collection of high-quality digital resources for your applications and projects.
