Video: "Irrefutable Proof for Moon Landing - Lunar Gravity"
I would say that this video
Irrefutable Proof for Moon Landing contains evidence of the opposite.
Here the description of the video:
Lunar gravity as determined from official NASA Apollo footage provides irrefutable proof for being filmed on the moon. In addition to the Apollo 14 SEQ Bay Pendulum the Apollo 16 Flying Bag is analyzed to provide g = 1.54 and 1.57 m/s2 in agreement with lunar gravity (g = 1.62 m/s2) and distinct from earth gravity (g = 9.81 m/s2). Therefore, both, pendulum and free fall motion confirm lunar gravity within a 5% error margin. Moon landing conspiracy theorists have accused NASA to simulate lunar gravity by using wires and decreasing playback speed, but failed to recognize that there is only ONE physically correct playback speed for such an operation: 41% = √(1/6) – as seen by using the equation P = 2π ∙ √(L / g) for the pendulum or t = √(2y / g) for free fall.
Consequently, it should be possible to restore the alleged original 1 g conditions by increasing the playback speed to 246% = √6. Under these conditions objects move as if accelerated by earth gravity (g = 9.81 m/s2) but movements of the astronauts become incredibly fast, showing the impossibility to simulate lunar gravity by slowing down footage recorded on earth.
All NASA footage obtained from public domain, AS14 SEQ Bay Pendulum cropped, AS16 Flying Bag animation with timer reproduced at 80% playback speed. All other footage reproduced at 100% (for lunar gravity) or 246% (for earth gravity) playback speed.
It is true that by reducing playback speed to 1/√6 ≈ 41%
= 9n41 we can transform the film of a terrestrial pendulum into a
lunar pendulum. The argument brought forward against such a playback speed reduction: "
movements of astronauts become incredibly fast". The quality of the film is so incredibly bad that at best we can say that the movements of the astronauts are
unnaturally fast. Yet it is far from impossible to perform or fake such unnatural movements on Earth.
Even more revealing is the
flying bag, reaching a height of only 4.1 m and a distance of probably less than 10 meter. Such a throw is certainly easy to perform on Earth, at least if the "bag" has (somewhere) enough weight. For comparison: Hammer throw world record is more than 80 m; on the moon such a hammer throw would result in more than 6 ∙ 80 m = 480 m.
Due to 1/6 gravity and lack of atmospheric friction, height and distance of a throw are at least 6 times bigger on the moon than on Earth. Therefore such a bag would easily have reached a height of 25 m and a distance of 60 m, if the throw actually had happened on the moon.
Again, the film quality is very poor, and the angle of the throw with respect to the camera has been chosen in such a way that we cannot verify whether the bag follows a genuine parabola or whether its longitudinal speed is decelerated by air friction.
However, there is a
smoking gun: Rotation of the bag is continuously slowing down, due to air friction. Here the corresponding sequence further slowed down:

We also get the impression that the part of the bag which first touches the soil after the throw is heavier than the rest of the bag. At t = 3.7 this heavy end becomes the lowest part of the bag. Because of more weight and/or less air friction, it then seems to pull the rest of the bag downwards. Thus, the heavy end remains the lowest part, and rotation has essentially stopped when the bag touches the soil at t = 4.5 with a vertically elongated shape (probably also created by air friction).
