I'll steal a bit of Mr. Keller's thunder. He notes, among other things, that the font in the title is inconsistent with that used in the 1960s, and further that the titles were added by the television stations -- not by NASA.

I added that the font is also anti-aliased, which was not a feature of the early video toasters. This suggests it was added with modern software techniques, i.e., Photoshop. But it's clearly intended to be part of the "original" so the author must answer for how his 1965 video contains modernly rendered text.

Further, the text is not monospaced, as was the requirement in the early video toasters. It's proportionally-spaced, centered text. It was clearly added with a software tool.

There is no doubt in my mind that this video clip is a modern production, perhaps using an older vidicon camera. Clearly a lot of thought and effort went into it, but not nearly enough to have it passed off as a "genuine fake".
