WAN 2.2 I2V - Crotch JOI

Concept

Sometimes the simplistic actions have amazing goon effect. This is a JOI(jerk off instruction) hand gesture, where the woman puts her hand in front of her crotch and pretends to be a man masturbating. A bit more traditional then my usual stuff on civ but hopefully equally enjoyable.

Usage

Base prompt is:

A video of a woman making a JOI gesture with her hand. She makes a fist with her hand and moves it up and down near her crotch.

You can then add one of :

The woman moves her hand fast.

The woman moves her hand slow.

How much difference this part of the prompt makes I'm still not sure, it definitely has some impact but maybe not as much as I'd like.

Making the video longer than 5 seconds often helps as it takes a few seconds for her to get her hand into position. If the woman's crotch isn't visible and the prompt doesn't tell the camera to move to show it, she'll jerk it around her navel, like in one of my example videos.

Training

The model was trained on 25 videos, 13 fast motion and 12 slower motion, all 5 seconds long and 16 fps. High noise was trained at 256 resolution with 6 frame buckets get the motion as accurate as possible. Low noise was 640 resolution with 2 frame buckets. 50 Epochs at 4 batch for High. 14 epochs and 2 batch for low, thankfully WAN already knows what hands look like. All trained on diffusion pipe on 3x3090s and 1x5060ti.

Captioning was automated using JoyCaption and DarkAges Llama 70B.
