Wan SCAIL-2 adds segmentation control with better auto-extend and less color shift
External_Trainer_213 · reddit · 2026-07-25
This post shares an update to a Wan SCAIL-2 segmentation-control workflow.
What changed
- The author says SCAIL Auto Extend has become the favorite sampler
- It appears to reduce color shifts
- It also no longer needs the separate Color Match option because that is now integrated
Features in the workflow
- Image Analyzer
- LoRA support
- Interpolate / Upscale / Color Match
- Color correction
- Image sharpener
- Sage Attention
- Two sampler choices
- Background remover to preserve the source video background
- SCAIL-2 Identity Tracker
- Optional alternate audio input
- Input-video interpolation
Usage notes
For multi-character scenes, the author recommends leaving object indices blank, switching the tracker to Point mode, and clicking characters directly in the image. Box mode can work, but may fail when more people are present. The workflow is framed as useful but not perfect, with seed changes or sampler switches often fixing issues.
