How to use Text-to-video

The Text-to-Video API transforms textual descriptions into dynamic video content. This guide will walk you through the process of generating videos from text prompts.

Overview

The Text-to-Video endpoint allows you to create videos by providing a text description (prompt) and various customization parameters. Our AI model interprets your text prompt and generates a video that matches your description.

Endpoint: POST https://app-api.pixverse.ai/openapi/v2/video/text/generate
API Reference : https://docs.platform.pixverse.ai/text-to-video-generation-13016634e0

Prerequisites

Before you begin, make sure you have:

A valid PixVerse API key

A different Ai-trace-id for each unique request

An active subscription plan with available credits or purchased credits

A clear text description of the video you want to generate

Step-by-Step Guide

1. Craft Your Text Prompt

The quality of your prompt significantly impacts the generated video. Here are some tips:

Be specific and descriptive

Include details about scene, movement, lighting, and atmosphere

Keep prompts between 25-200 words for optimal results

Examples of Effective Prompts:

✅ Good prompt: "A serene mountain lake at sunrise, with mist rising from the water. The camera slowly pans across the lake, capturing the golden sunlight reflecting on the surface. Birds fly overhead as the morning unfolds."

❌ Less effective prompt: "Mountain lake sunrise"

2. Prepare Your API Request

Construct your API request with the appropriate parameters:

3. Parameter Details

Parameter Name	Required	Type	Description
model	Required	string	v3.5
prompt	Required	string	=< 2048 characters
negative_prompt	Optional	string	=< 2048 characters
template_id	Optional	integer	Must activate effects in effects management before use. Some effects don't support certain resolutions, please check effects management
camera_movement	Optional	string	Add your camera_movement on your videos(supports v4/v4.5 model) supports value: "horizontal_left","horizontal_right","vertical_up","vertical_down", "zoom_in","zoom_out","auto_camera","crane_up", "quickly_zoom_in","quickly_zoom_out","smooth_zoom_in", "camera_rotation","robo_arm","super_dolly_out","whip_pan","hitchcock", "left_follow","right_follow","pan_left","pan_right","fix_bg"
style	Optional	string	"anime" "3d_animation" "day" "cyberpunk" "comic" Do not include style parameter unless needed
motion_mode	Optional	string	Default - "normal" "fast"(only allows 5-second duration) 1080p doesn't support "fast". If not provided, defaults to normal
duration	Required	integer	5,8 1080p doesn't support 8
quality	Required	string	"360p"(Turbo model), "540p", "720p", "1080p"
seed	Optional	integer	Random seed, int32 random number between 0 - 2147483647

4. Handle the API Response

The API returns a JSON response with a video_id:

{
  "ErrCode": 0,
  "ErrMsg": "success",
  "Resp": {
    "video_id": 0
  }
}

5. Check Generation Status

After creating the task, you will receive a video_id

Query periodically Get Video Generation Status API using this video_id

The status will change from 5 to 1 when processing is complete

  {
 "ErrCode": 0,
 "ErrMsg": "string",
 "Resp": {
   "create_time": "string",
   "id": 0,
   "modify_time": "string",
   "negative_prompt": "string",
   "outputHeight": 0,
   "outputWidth": 0,
   "prompt": "string",
   "resolution_ratio": 0,
   "seed": 0,
   "size": 0,
   "status": 5,
   "style": "string",
   "url": "string"
 }
}

6. Download the Generated Video

You can access a generated video with "url"

  {
 "ErrCode": 0,
 "ErrMsg": "string",
 "Resp": {
   "create_time": "string",
   "id": 0,
   "modify_time": "string",
   "negative_prompt": "string",
   "outputHeight": 0,
   "outputWidth": 0,
   "prompt": "string",
   "resolution_ratio": 0,
   "seed": 0,
   "size": 0,
   "status": 1,
   "style": "string",
   "url": "string"
 }
}

Common issue

Your video is stuck in "Generating" status and hasn't completed after a long wait.

Please check if you're using the same AI-trace-ID for every request. This is the most common cause of this issue.

Status codes: 1: Generation successful; 5: Waiting for generation; 7: Content moderation failure; 8: Generation failed;

If you encounter status code 7, it means your generated video was filtered by our content moderation system. Please modify your parameters and try again. Any credits used for filtered videos will be automatically refunded to your account.

Common error codes

400/500 status : Incorrect code

400013 : Invalid binding request: incorrect parameter type or value

400017 : Invalid parameter

500044 : Reached the limit for concurrent generations.
