LtxvApiTextToVideo - ComfyUI Built-in Node Documentation

The LTXV Text To Video node generates professional-quality videos from a text description. It connects to an external API to create videos with customizable duration, resolution, and frame rate. You can also choose to have AI-generated audio added to the video.

Inputs

Parameter	Description	Data Type	Required	Range
`model`	The AI model to use for video generation. “LTX-2 (Pro)” offers higher quality, while “LTX-2 (Fast)” is optimized for speed.	COMBO	Yes	`"LTX-2 (Pro)"` `"LTX-2 (Fast)"`
`prompt`	The text description that the AI will use to generate the video. This field supports multiple lines of text.	STRING	Yes	-
`duration`	The length of the generated video in seconds (default: 8).	COMBO	Yes	`6` `8` `10` `12` `14` `16` `18` `20`
`resolution`	The pixel dimensions (width x height) of the output video.	COMBO	Yes	`"1920x1080"` `"2560x1440"` `"3840x2160"`
`fps`	The frames per second for the video (default: 25).	COMBO	Yes	`25` `50`
`generate_audio`	When enabled, the generated video will include AI-generated audio matching the scene (default: False).	BOOLEAN	No	-

Important Constraints:

The prompt must be between 1 and 10,000 characters long.
If you select a duration greater than 10 seconds, you must also use the "LTX-2 (Fast)" model, a resolution of "1920x1080", and an fps of 25. This combination is required for longer videos.
