Fast Workflow Using Skyreels 2 I2V 1.3B

This is currently my preferred workflow, aside from Wan 2.1 FP8. The main reason is that it's three times faster than the 14B variant, while offering better quality than LTX—striking a great balance between speed and performance. That makes it my go-to choice for i2v tasks.

I'm using an RTX 4080 Super, and with Wan 2.1 running optimal settings, I can generate a video in about 5 minutes without frame smoothing. However, with this workflow, I can produce the same video in just 1 minute.
