Features

PixVerse V4.5 Text-to-Video Fast

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.
