LTX-2 19B ControlNet

LTX-2 19B ControlNet

LTX-2 ControlNet is a video-to-video transformation model that applies pose, depth, or edge guidance to generate new video content while preserving motion structure from the input. Built on the 19B DiT architecture, it supports synchronized audio handling with options to preserve original audio, generate new audio, or output silent video.

Why Choose This?

• ControlNet guidance modes Choose from pose, depth, or canny edge detection to guide video generation while preserving motion structure.

• Flexible audio handling Preserve original audio, generate new synchronized audio, or create silent output.

• High-fidelity output Leverages the 19B-parameter DiT architecture for detailed, temporally consistent video.

• Character-driven transformation Use a reference image to drive the appearance while the input video controls motion.

• Prompt Enhancer Built-in tool to automatically improve your prompts for better results.

Parameters

Parameter	Required	Description
video	Yes	Input video providing motion and structure
image	No	Reference image for appearance guidance
prompt	No	Text description of desired output
mode	No	Control mode: pose (default), depth, or canny
audio_mode	No	Audio handling: preserve (default), generate, or none
resolution	No	Output resolution: 480p, 720p (default), or 1080p
seed	No	Random seed for reproducibility (-1 for random)

Control Modes

Mode	Description
pose	Skeleton/pose guidance for human motion (default)
depth	Depth map guidance for scene structure
canny	Edge detection guidance for shape preservation

Audio Modes

Mode	Description
preserve	Keep original audio from input video (default)
generate	Create new synchronized audio
none	Output video without audio

How to Use

1. Upload your video — the input video providing motion structure.
2. Upload your image (optional) — reference image that defines appearance.
3. Write your prompt — describe the desired transformation.
4. Select control mode — pose, depth, or canny based on your needs.
5. Select audio mode — preserve, generate, or none.
6. Set resolution — 480p for speed, 720p for balance, 1080p for quality.
7. Run — submit and download the transformed video.

Pricing

Resolution	5s	10s	15s	20s (max)
480p	$0.15	$0.30	$0.45	$0.60
720p	$0.20	$0.40	$0.60	$0.80
1080p	$0.30	$0.60	$0.90	$1.20

Billing Rules

• Base price: $0.20 (720p, 5 seconds)
• Resolution multiplier: 480p = 0.75×, 720p = 1×, 1080p = 1.5×
• Minimum charge: 5 seconds
• Maximum billed duration: 20 seconds
• Total cost = (duration / 5) × $0.20 × resolution_multiplier

Best Use Cases

• Character Animation — Animate a character image with motion from reference video.
• Style Transfer — Apply a reference style to existing video content.
• Motion Preservation — Maintain motion structure while changing appearance.
• Video Editing — Transform video subjects while keeping movement.
• Dance Transfer — Apply dance moves to different characters.

Pro Tips

• Match the subject pose in your image to the starting pose in the video.
• Use pose mode for human/character motion, depth for scene structure, canny for edge-based guidance.
• Preserve audio for lip-sync scenarios, generate for new content.
• Iterate at 480p, then render final at 720p or 1080p.

Notes

• Maximum video duration is 20 seconds per job.
• Videos shorter than 5 seconds are billed as 5 seconds.
• For best results, ensure the reference image matches the subject type in the video.
