Let's talk about adding prompts to the templates. I have had some success. I've been doing lesbian videos of moms with their 18-20 yo daughters. I used OmniCreator to remove their clothes and put them in suggestive poses.
So with a kiss template where the women's hands aren't doing anything, I used a photo where the mom is grabbing her daughter's bare ass. I added a prompt that the older woman massages the younger woman's butt cheeks throughout the kiss, and MotionMuse complies.
I've had the same success with a photo of a mother in the middle and her two nude teen daughters touching each of her bare breasts. With a three way tongue kiss, I added a prompt that the women on the sides massage the middle woman's breasts throughout the kiss. I had the same success adding a breast massage to a French kiss template by adding a prompt. As the original template doesn't have the women doing anything with their hands, it works.
So I think you can add prompts that don't override the laws of physics or the behaviors in the template. For example, you can add a wedding ring to a finger that is hidden in the original photo but comes into view in the video.
I have a problem with character drift with MotionMuse, especially with longer videos. This especially occurs with MILFS where MotionMuse beautifies and de-ages them. I added this instruction with some success:
Keep the woman on the right identical to the source image. Maintain her age (42), facial proportions, wrinkles, skin texture, hairstyle, eye shape, nose, jawline, and overall identity. Do not beautify or de-age her.
I'm using OmniCreator to remove clothes and create suggestive poses. With the latter, it's hit or miss. Has anyone used OmniCreator to make NSFW videos?
