The Sandra project was done almost entirely with MiniMax H3 for creating video and Qwen for creating still images to guide the video.

While some people seem to be getting somewhat decent gore out of MiniMax H3, I was unable to convince MM to do a decent gutting.

On the venice.ai web site, however, a commercial website that lets you get away with gore (in some cases and with some AI models), I was definitely able to get Wan 2.7 to do a fairly decent gutting for me.

The problem was that venice.ai definitely won't allow you to create content of any kind with a character like 9 year-old Sandra. So, what to do?

Using Wan 2.7, I created this video using adult characters as a start: https://file.garden/aecQ3YtN8glaOMdJ/gc-posts/pull-out-guide.mp4

I tried to use the above video itself as a reference video for MM, but unfortunately MM just kept importing the video whole rather than using it to guide different characters.

What helped was using DaVince Resolve to mask off the appearance of the demo characters to make a video focused just on the intestines and the hand movements I needed.

That worked! (There are probably more sophisticated workflow techniques to get the same result, but I haven't learned them yet.) With the extraneous video content hidden MM happily transferred the gutting action to my Sandra and Sandra's mother characters.
