Wow, that "expert's" video is full of so many flaws.
1) First off, his stabilization of the video is crap. He couldn't even lock the horizon in place. You can see the entire video bouncing around. It looks like he used a half assed automatic warp stabilizer set to position, scale, rotate which had a very hard time finding a good point to stabilize. If this is a real "expert" it's not a very good one.
2) At 2:36 in the video he claims the "trees and grass are smearing around and moving around more than the UFO", and he says "this is because of compression". He says "you can't blame that on motion tracking, it could as well be compression for all I know"....
The guy doesn't know what he is talking about. The trees and grass were smearing around and moving around because he is looking at a very badly stabilized video that was originally shaking around.
That "smearing" is MOTION BLUR, not compression. When you shake a camera around it causes very small motion blur streaks on objects, and when you stabilize the video you still see the pixels making streaks, and it appears like smearing. Stabilization can't get rid of streaks/smear, all the pixel data remains the same.
Shaking a camera also makes light rays pass over the border between each pixel on the CCD, and that causes what looks to be like pixels flickering as the light rays are not exactly hitting 1 CCD pixel but are hitting the edge between 2 CCD pixels, and it makes them appear different for a split second.
What expert would blame that on compression? There is no such compression algorithm that "smears" things around. Compression algorithms only reduce the amount of unique colors in a video in order to reduce the size of the definition table and make the over all pixel data compression more simplified. Compression algorithms find the most commonly used colors in a video, and then changes the least common colors to the nearest common color it matches. This causes blocks to appear because it does this check in small blocks, and can sometimes appear like someone did a "flood fill" on some pixels. Compression WILL NOT cause something to smear around or jump around excessively.
My video is PROOF that the video is fake:
What you see is NOT a result of compression...
As you can see, the UFO jumps around to different positions when the girl's body passes over it. This is a VERY common mistake when people composite fake objects into a scene and try to make other objects pass in front of it. It's called "position consistency", or "inconsistency" in this case.
This error actually gives you a clue on how they motion tracked the video in order to "match move" the UFO into the video.
The UFO jumps around because the tracking point that was tracking the movement of the video was on the left tree. When the girls body blocked the left tree from view, this made the tracking point get lost, and jump around, and it even started to track the girls body so the UFO jumps down for a frame because the girl's body was moving down. Then when the girls body was no longer blocking the tree from view the UFO snaps back into place because it can now see the tree (the original tracking point) and know where it is supposed to be. The creater of the video either didn't notice or didn't take the time to fix it.
I highly doubt the guy in that video is an expert. I would put my money on him being the creator though! Only because he is in contact with the original uploader, he sucks at stabilizating video which is what caused the error above, and because he took this so personal and resulted to personal attacks (he didn't like people pointing out his errors).
