I have not taken the time to verify where the videos came from, but I have seen many of the moon hoax and flat earth documentaries and I will admit, as a glober who thinks the moon landings happened largely as described, that those videos are obviously evidence that NASA passes off CGI to the public. The only explanation for the astronauts going static and blinking in and out while the background remains steady is that it is CGI.

So there is an "out" that those videos are themselves faked. To be thorough, I would have to verify that they did come from NASA as supposed ISS feed. But assuming they are real, IMO that does not prove that the space program is fake. Like I have said elsewhere, a few weeks ago there were a bunch of obviously fake videos of Netanyahu, leading to theories about his death. Now, most everyone says he is probably alive. So those videos were released for a different reason. I can think of a few reasons why the government might try to pass off CGI as real video to the public other than hiding a secret.

Other than that, overall I have found the various conspiracy documentaries about NASA and especially the Apollo program to be pretty weak. Some are flat earth of course. But even those that agree with the size and shape of the earth and distance to the moon and just say that the landing was fake tend to appeal to things that are just wrong. Like the "phone call on the moon" for example, or the rocket "turning sideways and going out (and falling into) the ocean." No one ever explains why the phone call on the moon is impossible. And in addition to the rocket turning sideways being the correct (i.e. most efficient) way to get to space, NASA even says that the first stage falls into the ocean.

So, if I am going to take someone claiming that all of NASA is a hoax seriously, they need to be serious enough to not say stupid stuff like this.
