Start-end-to-video

Vidu Q2-Pro-Fast Start-end-to-Video is an advanced AI video generation model that brings static images to life. Upload a reference image and describe the motion you want — the model generates high-quality video with smooth animation, optional audio, and cinematic quality up to 1080p.

Vidu Q2-Pro-Fast Start-End-to-Video

Vidu Q2-Pro-Fast Start-End-to-Video is a high-speed, professional-grade AI video generation model that creates smooth video transitions between two images. It delivers the visual quality of Q2-Pro at significantly faster generation speeds — giving you precise start-to-end frame control without the wait, ideal for iterative and production workflows.

Why Choose This?

  • Faster speed Significantly reduced generation time compared to Q2-Pro, without sacrificing transition quality.

  • Precise frame control Define exactly where the video begins and ends with two reference images.

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

  • Flexible duration Create videos from 1 to 10 seconds in length.

  • Audio generation Optional synchronized audio and background music.

  • Prompt Enhancer Built-in tool to automatically improve your transition descriptions.

Parameters

ParameterRequiredDescription
promptYesText description of the transition, motion, and action between frames
start_imageYesThe first frame image (URL or upload)
end_imageYesThe last frame image (URL or upload)
resolutionNoOutput quality: 540p, 720p (default), 1080p
durationNoVideo length in seconds (1-10, default: 5)
generate_audioNoGenerate synchronized audio (default: enabled)
bgmNoAdd background music (default: enabled)
seedNoRandom seed for reproducibility

How to Use

  1. Upload your start image — provide the image representing the first frame of the video.
  2. Upload your end image — provide the image representing the last frame of the video.
  3. Write your prompt — describe the transition, motion, and how the scene evolves between frames.
  4. Set resolution — choose 540p for fast previews, 720p for standard quality, or 1080p for premium output.
  5. Adjust duration — set video length up to 10 seconds.
  6. Configure audio (optional) — enable/disable audio generation and background music.
  7. Run — submit and download your video.

Best Use Cases

  • Iterative Workflows — Rapidly prototype and refine transition concepts between start and end frames.
  • High-Volume Production — Generate large sets of frame-to-frame transitions efficiently.
  • Marketing & Ads — Quickly produce dynamic before-and-after or product-reveal videos.
  • Social Media Content — Create polished transition clips at scale for Reels, TikTok, and Stories.
  • Agency Pipelines — Fit professional-quality video transitions into tight production schedules.

Pro Tips

  • Use the Prompt Enhancer to refine your transition descriptions efficiently.
  • Ensure start and end images share a compatible composition for the most natural transition.
  • Be specific in your prompt about how the motion or transformation should unfold between frames.
  • Keep subject framing consistent between start and end images for smoother interpolation.
  • Use 540p or 720p for rapid iteration and switch to 1080p only for final deliverables.
  • Enable generate_audio for synchronized sound effects that complement the transition.

Notes

  • All three fields — prompt, start_image, and end_image — are required.
  • Maximum video duration is 10 seconds.
  • The model interpolates motion and scene content between the two provided frames.
  • Audio generation adds synchronized sound effects and ambient audio.
  • BGM adds background music appropriate to the scene mood.
  • Ensure uploaded image URLs are publicly accessible.
