Experts also claimed there was a network connections between Trump Tower and Russia's Alpha Bank servers in 2016. Turned out that was completely false and a low grade network analyst could see it was false. So I take everything so-called experts say with a grain of salt.
The analysis does not show that anything in the video was actually changed or that the video is not real. Conspiracy theorists love to come up with all kinds of superfluous arguments to support their theories.
Consider the issue they made out of the one minute gap in the videos that Pam Bondi did such a horrible job of explaining. Who knows what the real; explanation is, but I can state with absolute certainty that no one broke into that prison, entered Epstein's cell, strangled him and made it look like suicide, then absconded, in 60 seconds. It is not physically possible. It takes longer than that for a human do die from strangulation.
If there is an objective expert out their who can look at the video and give an honest assessment of its authenticity, then I would love to see what he has to say. Otherwise, I choose to ignore these self-appointed experts identified by media like Wired.
