Pixverse c1 Start-End-to-Video API by PIXVERSE

pixverse/c1/start-end-to-video
Start-end-to-video

Pixverse c1 Start-End-to-Video model. High-quality video generation from image prompts.

PixVerse C1 Start-End-to-Video

PixVerse C1 Start-End-to-Video gives you precise control over video generation by letting you define both the first and last frames. Upload a start image and an end image, describe the transition, and the model generates a smooth cinematic video connecting the two frames.

Why Choose This?

  • Full frame control Define exactly where the video starts and ends.

  • Smooth transitions Generate natural, fluid motion between two keyframes.

  • High resolution output Generate videos in 360p, 540p, 720p, or 1080p quality.

  • Flexible duration Create videos from 1 to 15 seconds in length.

  • Audio generation Optional synchronized audio that matches your scene.

Parameters

ParameterRequiredDescription
promptYesText description of the desired motion and transition
imageYesStarting frame (from image upload API)
end_imageYesEnding frame (from image upload API)
modelYesModel name (default: c1)
durationNoVideo length in seconds (1-15, default: 5)
qualityNoOutput resolution: 360p, 540p, 720p (default), 1080p

seedNoRandom seed for reproducibility

How to Use

  1. Upload start image — call the image upload API to get the start frame.
  2. Upload end image — call the image upload API to get the end frame.
  3. Write your prompt — describe the motion and transition between the two frames.
  4. Set quality — choose resolution based on your quality and speed requirements.
  5. Adjust duration — set video length up to 15 seconds.
  6. Configure audio (optional) — enable or disable synchronized audio generation.
  7. Run — submit and download your video.

Best Use Cases

  • Controlled Transitions — Create precise scene transitions between two specific moments.
  • Product Showcases — Animate between product states (before/after, open/closed).
  • Story Sequences — Connect two story moments with smooth animation.
  • Camera Movements — Define start and end compositions for cinematic shots.
  • Visual Effects — Generate transformation effects between two states.

Pro Tips

  • Describe intermediate motion explicitly in the prompt (e.g., "the door slowly swings open").
  • Use images with matching lighting conditions for natural-looking transitions.
  • Keep duration proportional to the complexity of the motion between frames.
  • Upload both images via the upload API before submitting the generation request.
