SCAIL-2 video generation looks strong, but a 9-second clip took 30 minutes
A user tested SCAIL-2 (Wan2gp) for the first time and said the output quality was impressive, including a convincing simulation of a dress lifting when the feet were obscured.
Performance report
- 9-second video
- Generated at 384p, 16:9, 60 fps
- Took about 30 minutes at 10-step inference
- The user compares this with LTX2, which reportedly takes 2–5 minutes at similar resolution on a 4070 Ti Super with 64 GB RAM
The post asks for tips to improve render time, suggesting the current bottleneck is runtime rather than visual quality.
