The modern tendency is, readers being unfamiliar with "belied" and "compare" as a noun, is to think it's "Than any [that] she belied with false compare." We are also unfamiliar with the use of "she" here.
Since this thread is current again after nine months away, I'll come back with something sensible to add alongside my silly response to Ann. I just watched these (about the first 10 at least) for the first time. Very nice. I love Maddy's hip-hop rendition! There are a lot of Sonnet 18 aren't there? I imagine they were allowed to choose and many stuck with the familiar. But it's all lovely to see and very heartening. Belated thanks for posting Sam.
