• Low Noise - try between 0.5 to 1 strength (I2V). Lower strength if you are experiencing face changes. Closer to 1 for (T2V).
• This model technically works without the Low Noise model (I2V) because the base model is trained on kissing to some degree.
• May need to bring the faces closer otherwise could do some air french kissing. "the man leans towards the woman" type of thing.
• Try prompting like this for longer french kissing scenes:

(AT 0-1s) the woman leans towards the woman and begins french kissing her

(AT 2-4s) the woman continues to french kiss the woman.
