Workflow Testing and Usage Instructions:

1. In this round of testing, I tried different schedulers and sampling steps, and I ultimately preset it to use `flowmatch_distill` with 4 sampling steps. When using other schedulers, the reference character's consistency tends to degrade to varying degrees, which isn't ideal when the main goal is swapping the head. Of course, you can still experiment with other schedulers and sampling steps. 

2. The `lightx2v_elite_it2v_animate_face` Lora is a big help for maintaining the reference character's consistency. I recommend using a strength value between 1.2 and 1.5. However, using a higher strength can sometimes cause unpredictable textures in the swapped area. To solve this, I've preset a pixel restoration group that you can use to fix some of these video details. If you have enough VRAM on your local machine, or if you're using this workflow online, I also recommend using a 48G GPU to upscale the video for a clearer result.
