Pixverse v4.5 turns text prompts into high-quality videos with multiple resolutions, aspect ratios, and motion modes. Ready-to-use REST inference API, best performance, no coldstarts, affordable pricing.

Features

PixVerse V4.5 Text-to-Video is a high-quality text-to-video generation model with support for resolutions up to Full HD 1080p. Generate detailed, cinematic videos from text descriptions with flexible aspect ratios and multiple resolution options.


Why It Stands Out

  • Up to 1080p Full HD: Generate crisp, high-resolution videos for professional use.
  • Multiple resolutions: Choose from 360p, 540p, 720p, or 1080p based on your needs.
  • Prompt Enhancer: Built-in AI-powered prompt optimization for better results.
  • Flexible aspect ratios: Wide range from 16:9 widescreen to 9:16 vertical.
  • Negative prompt support: Exclude unwanted elements for cleaner outputs.
  • Reproducibility: Use the seed parameter to recreate exact results.

Parameters

ParameterRequiredDescription
promptYesText description of the video you want to generate.
aspect_ratioYesOutput aspect ratio: 16:9, 4:3, 1:1, 3:4, 9:16.
resolutionYesOutput resolution: 360p, 540p, 720p, 1080p.
durationNoVideo length: 5 or 8 seconds (default: 5).
negative_promptNoElements to avoid in the output.
seedNoSet for reproducibility; leave empty for random.

Supported Resolutions

ResolutionBest For
360pQuick previews, drafts, low-bandwidth use
540pSocial media, balanced quality and speed
720pHD output, general professional use
1080pFull HD, premium quality, final delivery

Supported Aspect Ratios

Aspect RatioBest For
16:9YouTube, widescreen displays
4:3Classic format, presentations
1:1Instagram posts, social media squares
3:4Portrait photos, Pinterest
9:16TikTok, Instagram Stories, Reels

How to Use

  1. Write a prompt describing the scene, action, and style you want. Use the Prompt Enhancer for AI-assisted optimization.
  2. Select aspect ratio — choose the format that fits your platform.
  3. Select resolution — choose 360p for drafts, 1080p for premium output.
  4. Set duration — choose 5 or 8 seconds.
  5. Add a negative prompt (optional) — specify elements to exclude.
  6. Click Run and wait for your video to generate.
  7. Preview and download the result.

Best Use Cases

  • Cinematic Content — Generate 4K-style cinematic shots and scenes.
  • Social Media Content — Create platform-optimized videos for any channel.
  • Marketing & Advertising — Produce high-quality promotional videos.
  • Sci-Fi & Fantasy — Generate detailed, imaginative scenes.
  • Rapid Prototyping — Use lower resolutions for quick concept testing.

Pro Tips for Best Quality

  • Be detailed in your prompt — describe subject, action, environment, lighting, and style.
  • Include quality keywords like “4K,” “cinematic shot,” or specific visual descriptions.
  • Use 360p or 540p for quick iterations, then generate final version at 1080p.
  • Use negative prompts to reduce artifacts like blur or distortion.
  • Match aspect ratio to your target platform before generating.

Notes

  • Processing time varies based on resolution, duration, and current queue load.
  • For faster generation at lower cost, consider PixVerse V4.5 Fast.
  • Please ensure your prompts comply with content guidelines.
