Will wait for Alvaro to run some tests and then merge.

@sayakpaul The t2v ghibli one works now without a problem, but the other one for I2V has uncoverted layers so it doesn't work. Not sure if it's a musubi trained one though so also not sure if it corresponds to this PR.

Thanks for testing @asomoza! I will look into it.

@asomoza fixed.

I would like to request you to host the CivitAI checkpoints in some temporary repository on the Hub for testing if possible. Speeds up my development time.

Sure, no problem, I'll surely do it if this issue happens again but this is probably the only one from me since now I can use the loras I needed for the guide.

the I2V one works now, thanks a lot!
