Person used in video verbal contract

[That playdough]

Hello, I do YouTube videos and I did one with a girl who on camera gave me verbal consent to using our interaction for my video and to post it online. However after posting it and it getting some attention she’s asking me to take her part out of the video. This means for me to potentially lose money and any growth for my channel. I’m wondering do I need to take it out and are they I’m breach of contract?

I’m located in California, usa
Thanks

Do you make so much money with the video that it's really worth a confrontation with her? I mean there is always the chance that a post of her complaining about you with a catchy hashtag goes viral ...
