Didn't work with the 2.3 - i2v

First of all, kudos for giving a general dance loras a try. There are not many of those around.

Ran the same workflow with and without the lora:

I would say the lora is overfitted. The dance seems to become more fluent and flexible but they are dancing less to the beat, the "white room" comes through once and in general the faces and clothes morph more with the lora.

Like, check the beginning where the bottom video is more or less "on beat" while the top seems to move closer to half the beat.

RuneXXs musicvideo workflow was used. 5 segments, 887 frames each
