It was also a mainstream news story for days that the White House spread a doctored video which was sped up to make it look like a CNN reporter attacked a White House intern. Thing is, it was trivial to verify that wasn't at all true: if you actually compare the speed with the original frame by frame it's not sped up anywhere. The artifacts some reporters claimed were from it being sped up are actually frame rate upconversion from the exact, specific 15 FPS GIF its original poster claimed as his source.[1] On the other hand, there was a super-viral video about this on Twitter that was really obviously doctored. It "proved" that parts had been sped up by overlaying the video on a 7-frame-behind version of the original. Unless you paused the video this desync was only noticable in faster-moving sections, creating the illusion those sections were sped up. Not one news reporter spotted this. People like Captain Disillusionment happily spread it as fact. If we based our decisions about what's doctored and should be blocked from spreading and what isn't on the media reporting, it'd mean treating truth as lies and lies as truth. [1] Seriously. You can replicate the incredibly simple frame rate conversion (just blending the frames on either side) in a few lines of Python and get every single one of those artifacts out: https://www.makomk.com/2018/11/16/recreating-that-white-house-video-in-14-lines-of-python/ https://www.makomk.com/2018/11/16/recreating-that-white-hous... From what I can tell this is the default setting in Sony Vegas, which is what the guy used.
