Well, as far as some of the stuff in that video goes:
1) The first scene with the bubble coming up—the video says that such a thing could only happen in the underwater training tanks. How do we know that that part of the video wasn’t just that: archival film of the Chinese training in the water tanks before going into space?
2) The other scenes with “bubbles” moving from the one hatchway—those could be something other than bubbles. Little bits of debris, for example, being knocked out into space.
3) The flag waving—okay, that flag did not wave “like it is underwater”.
4) The mysterious reflected lights—camera lights?
5) The astronauts (I forget what the Chinese call them) don’t let go of the spacecraft—gee, perhaps they didn’t want to go floating off helplessly into space? Maybe they actually had work to do?
6) The Earth is always in the same position—that’s the way it often works with orbiting spacecraft, unless you put spin on the vessel. You have one side of the spacecraft always facing towards the Earth. You’d always have the Earth occupying the same space in the sky if you look at it from the same angle. When the narrator writes disbelievingly “Somehow the craft’s movement matches the Earth’s exactly? For hours?”, that’s just showing how little he knows about such things. There are satellites up there that have matched the Earth’s movement for years.
7) The clouds on the planet are moving too quickly—you also have to add in the speed of the spacecraft; unless it’s locked in a geosynchronous orbit, then it can be flying around the planet at a rather considerable speed.
8) The clarity of the video in comparison to other space missions—technology changes. And is the quality really any better?
9) The incriminating official websites—even if I could read Chinese, those images of the websites would be far too blurry to read
All in all, I don’t see any of these claims proving anything. The spacewalk footage could be faked, sure, but none of this evidence conclusively shows that to be the case.
