I'm sure you've noticed, given your keen observational skills, that the edited footage in the second half of the video has a stretched, more pixelated look to the original and has greatly increased linear jitters.
I think we must question the degree to which this youtuber (or whoever he stole the footage from) has "corrected" the image. How did he decide how much distortion to "remove" or "correct"? He gives zero details. How much fish eye effect was present in the original film? Does he know what exact type of lens was used? Was it a careful calculation to compensate for the exact amount of distortion in the lens...?
Or did he just keep going till the horizon looked flat?
My guess is it's the latter, especially given all the Flat Earth links he lists in the description, where he really should have detailed his calculations.
Wrong. The information in the description is exactly the same. He doesn't demonstrate that he knew the measurements of the "fish-eye" lens that he is "correcting" to look like "35mm", nor does he demonstrate that such "corrections" better reflect reality and do not result in further distortion, which given the state of the footage in the 2nd half of the video, they clearly seem to.
Furthermore, the "35mm" number refers to film negative, not a camera lens measurement:
He stats this in a comment in the video, if it is of any help.
Any good video editing software can remove the fisheye. I use Adobe After Effects for film editing and what was used for this video. Gopro's own Software now provides a tool to remove the fisheye effect. So anyone can do this.
His talk of 35mm shows he has no clue what he's doing and has simply edited the footage to make the horizon flat throughout.
When you do such auto effects on Adobe software you are asked what lens was used to video the original footage, and there are many lenses to choose from all with different measurements. Based on their measurements the algo will make adjustments. If you don't know the original lens measurements, and I doubt this clown did, you can do it arbitrarily instead of choosing an exact measurement. This is probably what he did, arbitrarily edited the horizon to be flat throughout.

Right. Here is the original video of how we can remove the Fisheye Camera effect that is seen in 99% of all Space Agency footage.

Actually 6 years old, from 2017.

A camera that takes 35mm film can often use different lenses of a variety of sizes and types. Including, indeed, a fish eye lens, ironically enough.
It's funny that, as a filmmaker (as he describes himself) he is not aware of such things.
