Film and TV technology to fake it existed, the man on the video is wrong, quality of the landing footage was so bad you could make it on the fly with static camera filming screen in projection room instead of telecine. Did they fake it? Highly unlikely.
I'm often surprised people question moon landing, which would require a lot of effort and staff to fake but rarely anyone doubts Gagarin's flight, which as a story not only has less material proof (in terms of media coverage), more conspiracy adaptable "issues" and "plot holes", but historically, in part is also 100% proven to be far from truth (as in Russians at the time said the flight ended in manned landing as it wouldn't count otherwise, then decades later officially admitted they lied, the capsule was in fact empty when it slammed and plowed the ground plummeting from the sky).
Why is it always only the events that would require superb precision, surgical finese and mastery, all of which American government desperately lacks, generate so many conspiracy theories, but the obvious eye brow lifting, highly unlikely news "true stories" outside of US never attract as much attention?
