About

Faster slight quality reduction compared to LTX-Video 13b

Example Output

Prompt:

"A woman with light skin, wearing a blue jacket and a black hat with a veil, looks down and to her right, then back up as she speaks; she has brown hair styled in an updo, light brown eyebrows, and is wearing a white collared shirt under her jacket; the camera remains stationary on her face as she speaks; the background is out of focus, but shows trees and people in period clothing; the scene is captured in real-life footage."

Input Parameters

fps Type: integerDefault: 24Range: 1 - 60: Frames per second for the output video.
seed Type: integer: Random seed for reproducible results. Leave blank for a random seed.
image Type: string: Input image for image-to-video generation. If provided, will generate video from this image.
video Type: string: Input video for video-to-video generation. If provided, will generate video from this video. Takes precedence over image if both are provided.
prompt (required) Type: string: Text prompt for video generation
go_fast Type: booleanDefault: true: Enable fast mode with skip layer strategies (20-40% faster but slightly lower quality).
num_frames Type: integerDefault: 121Range: 9 - 257: Number of frames to generate.
resolution Default: 720: Resolution for the output video (height in pixels).
aspect_ratio Default: match_input_image: Aspect ratio for the output video.
guidance_scale Type: numberDefault: 3Range: 1 - 10: Guidance scale. Recommended range: 3.0-3.5.
negative_prompt Type: stringDefault: worst quality, inconsistent motion, blurry, jittery, distorted: Negative prompt for video generation.
denoise_strength Type: numberDefault: 0.4Range: 0 - 1: Denoising strength for final refinement step.
downscale_factor Type: numberDefault: 0.667Range: 0.1 - 1: Factor to downscale initial generation (recommended: 2/3 for better quality).
conditioning_frames Type: integerDefault: 21Range: 1 - 50: Number of frames to use for video-to-video conditioning (only used when video input is provided).
num_inference_steps Type: integerDefault: 24Range: 2 - 50: Number of denoising steps for initial generation.
final_inference_steps Type: integerDefault: 10Range: 1 - 50: Number of inference steps for final denoising.

IMAGEIO FFMPEG_WRITER WARNING: input image is not divisible by macro_block_size=16, resizing from (853, 480) to (864, 480) to ensure video compatibility with most codecs and players. To prevent resizing, make your input image divisible by the macro_block_size or set the macro_block_size to 1 (risking incompatibility).
