Workflow Overview: Lightspeed Wan Series
These workflows are optimized for the Lightspeed Wan 2.1 and 2.2 Image-to-Video (I2V) models by darksidewalker. They are categorized into the streamlined SVI-V2-Pro series and the feature-rich Standard (v12 and below) series.
1. SVI-V2-Pro-I2V (Barebone Series)
The SVI series is designed for users who want a clean workspace without unnecessary overhead. It focuses on the core I2V logic with two critical utility modules.
A. Resolution Management (Resolution Master)
To ensure compatibility with Wan 2.2’s specific latent requirements, the source image must be precisely resized.
Step 1: Load the source image into the Load Image node.
Step 2: Use the dropdown (next to the TV icon) to select a target resolution (e.g., 480p, 720p).
Step 3: Click the TV Icon to activate the selection.
Step 4: Under 'Actions', set the slider to 16 and click the Snap button.
Note: This "snapping" ensures the dimensions are multiples of 16, preventing tiling artifacts or model errors.
B. Temporal Smoothing (Interpolation)
Located in a dedicated group, this module handles frame rate conversion.
Primary Use: Converting low-FPS raw generations (e.g., 16 FPS) into smooth, high-fidelity output (e.g., 60 FPS).
2. Standard Wan Workflows (v12 and Below)
The legacy/standard workflows are "all-in-one" solutions, containing a broader suite of post-processing and utility tools:
Image to Video
The core generative engine for Wan 2.1/2.2.
FLF Loop
Facilitates seamless looping by utilizing First-Last Frame logic.
Downscale Image
Safely shrinks oversized source images to prevent VRAM OOM (Out of Memory) errors.
Extract Last Frame
Pulls the final frame of a generation to be used as a starting point for the next clip (Storyboarding).
Combine Videos
Merges multiple generated clips into a single sequence.
Interpolation
Increases frame rate for smoother motion.
Upscale Video
Increases the spatial resolution of the final video output.
Description
Release Notes: Wan 2.2 I2V (SVI V2 Pro Edition)
This is a streamlined, "no-frills" version of the Wan 2.2 Image-to-Video workflow, specifically rebuilt to utilize SVI V2 Pro for generating (potentially) stable, longer-duration videos.
Key Features
6-Stage Sampler Architecture: The workflow is divided into six distinct sampler groups.
Granular Prompt Control: Each sampler group contains its own CLIP Text Encode node, allowing for precise positive prompt adjustments across different stages of the generation.
The "Lazy Positive Prompt" Option: * For a simplified experience, a primitive node labeled "Lazy Positive Prompt" is connected to all stages.
Usage: Simply enter your prompt here to apply it globally. To use individual prompts per sampler instead, just delete this node.
Dedicated Interpolation: The only additional feature included is a separate group dedicated to video interpolation.
Important Disclaimer
Please note that this workflow was updated by request. I have no prior experience with SVI (Stable Video Interpolation) before this build.
If you require a workflow with advanced "bells and whistles" or a more seasoned implementation of SVI logic, I strongly recommend exploring more established community workflows. This version is intended for those who prefer a transparent, manual setup without hidden complexities.
