Maybe there's not much value in editing what someone said after all
criminal value... maybe?
There are absolutely scams right now that use deepfakes to trick people.
Of course there is commercial value. The cost of reshooting video materials is huge. You made an advert mentioning 3 features, but by the time the product is about to be released one of them got dropped or even worse changed? Congrats, you need to get the talent and the studio rebooked, you need to find a new tech crew, who need to set up again. Probably things won't cut seamlessly so you need to re-record the whole thing.
