LTX-Video

Generate videos from text prompts or input images with configurable aspect ratio, resolution, and inference steps. LTX-Video works best with long, descriptive prompts.

Quick Start

Requires an each::labs API key. Get one at eachlabs.ai.

curl -X POST https://api.eachlabs.ai/v1/prediction \
  -H "Content-Type: application/json" \
  -H "X-API-Key: $EACHLABS_API_KEY" \
  -d '{
    "model": "ltx-video",
    "version": "0.0.1",
    "input": {
      "prompt": "best quality, 4k, HDR, a tracking shot of a beautiful coastal scene with waves rolling onto sandy beach at golden hour",
      "aspect_ratio": "16:9",
      "length": 97,
      "steps": 30,
      "cfg": 3
    }
  }'

Parameters

Parameter	Type	Default	Description
aspect_ratio	string	3:2	Output aspect ratio. enum: 1:1, 1:2, 2:1, 2:3, 3:2, 3:4, 4:3, 4:5, 5:4, 9:16, 16:9, 9:21, 21:9
cfg	number	3	How strongly the video follows the prompt
image	string	-	Optional input image to use as the starting frame
length	integer	97	Number of frames
negative_prompt	string	low quality, worst quality, deformed, distorted	Things you do not want to see in your video
prompt	string	best quality, 4k, HDR...	Text prompt for the video. Works best with long descriptive prompts
seed	integer	-	Set a seed for reproducibility. Random by default
steps	integer	30	Number of steps
target_size	integer	640	Target resolution size
