I am also having trouble getting a liquify effect to follow the motion of an actress accurately.
My footage is slightly similar to the demon face, but instead, a model opens her mouth ridiculously large and devours another model like a snake. I can get only a small section to look good using the “demon face” demo. I am using the eyes as tracking points, but as the models mouth trembles, the effect looks terrible because it effects the chin rather than just the mouth- any suggestions?
Thank you so much from the heart of a newbie,
