How'd they do that? Special Effects question

My daughter was watching the Rob Thomas video for “Her Diamonds” and was asking me how they made it look as if the woman was embedded in ice. I had to allow as I had no idea.

Any thoughts on this - either if you know or have an idea of how you could make it look as if someone were covered in slowly melting ice?

Feel free to use this thread to ask other similar questions if you like.

It looks like, when she’s completely covered, there are cgi-created full body shots from a distance and close-up face shots with the woman behind a plastic covering. When she’s melting, it could just be gels and such. There are some shots that look like water running down hard plastic (2:05) and some shots that look like she’s covered in some gelatin (2:08). Probably some cgi tossed in there too.

This question is less “how did they do it” than “how does it look”…

I’ve never been in the live audience of Saturday Night Live, but on a board like this, I have no doubt someone has. I’ve always wondered, when I see special effects on screen - like, for example, a wavy-lines “entering a dream sequence” effect, or a face in a cloud above someone’s head to indicate an imaginary dialog - how does the live audience see such things? Or are any sketches with such effects all pre-recorded and shown on a big screen to the live audience?

I’ve never seen SNL in person, but I believe they have several monitors scattered around the stage/audience viewing area. When special on-screen effects are used, the audience is probably told to watch the monitors in addition to the action on stage.
