Try it on WaveSpeedAI!Pixverse v4.5 Fast 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 Fast is a versatile text-to-video generation model optimized for speed. Generate high-quality videos from text descriptions with multiple resolution options — from quick 360p previews to crisp 720p HD output.
Why It Stands Out
- Fast processing: Optimized for quick video generation.
- Multiple resolutions: Choose from 360p, 540p, or 720p based on your needs.
- Prompt Enhancer: Built-in AI-powered prompt optimization for better results.
- Flexible aspect ratios: Support for various aspect ratio presets.
- Negative prompt support: Exclude unwanted elements for cleaner outputs.
- Reproducibility: Use the seed parameter to recreate exact results.
Parameters
| Parameter | Required | Description |
|---|---|---|
| prompt | Yes | Text description of the video you want to generate. |
| aspect_ratio | Yes | Output aspect ratio: 16:9, 9:16, 1:1, etc. |
| resolution | Yes | Output resolution: 360p, 540p, 720p. |
| duration | No | Video length: 5 seconds (default: 5). |
| negative_prompt | No | Elements to avoid in the output. |
| seed | No | Set for reproducibility; leave empty for random. |
Supported Resolutions
| Resolution | Best For |
|---|---|
| 360p | Quick previews, drafts, low-bandwidth use |
| 540p | Social media, balanced quality and speed |
| 720p | HD output, final delivery, professional use |
How to Use
- Write a prompt describing the scene, action, and style you want. Use the Prompt Enhancer for AI-assisted optimization.
- Select aspect ratio — choose the format that fits your platform.
- Select resolution — choose 360p for drafts, 720p for final output.
- Set duration — 5 seconds.
- Add a negative prompt (optional) — specify elements to exclude.
- Click Run and wait for your video to generate.
- Preview and download the result.
Best Use Cases
- Social Media Content — Create platform-optimized videos for TikTok, Reels, and Shorts.
- Rapid Prototyping — Use 360p for quick concept testing.
- Marketing & Advertising — Produce promotional videos and ad creatives.
- Action & Sports — Generate dynamic slow-motion and action sequences.
- Creative Projects — Bring imaginative concepts to life.
Pricing
| Resolution | 5 seconds |
|---|---|
| 360p | $0.50 |
| 540p | $0.50 |
| 720p | $0.70 |
Pro Tips for Best Quality
- Be detailed in your prompt — describe subject, action, environment, lighting, and style.
- Use 360p or 540p for quick iterations, then generate final version at 720p.
- Include motion keywords like “slow motion,” “dynamic,” or “cinematic.”
- Use negative prompts to reduce artifacts like blur or distortion.
- Match aspect ratio to your target platform before generating.
Notes
- Processing time is optimized for speed — expect quick turnaround.
- Please ensure your prompts comply with content guidelines.
