niftski certainly has the skill to pull this off, but does he have enough time?

To avoid another minecraft style fake I watched the full twitch stream frame by frame and noticed something unusual.

Multiple times there were fine adjustment of the keyboard position, niftski was more concerned with the keyboard placement than the touch, at one point, after a lot of keyboard adjustment and camera adjustment, he was satisfied with the keyboard position without first touching the keys again, sometimes the game was paused while keyboard was being adjusted.

I watched the RGB transition closely, only to have the camera violently shaked and I couldn't get a seamless transition, niftski has the eye and hand and technical skill to make overlay video run seamlessly.

When niftski pick up the cam to look at the chat window, the text were blurred and username color did not match.

In the stream, niftski demonstrated the ability to replay game video to overlay existing live stream.

There was a huge pause of video before face cam.

niftski paused for a few days before this run.

niftski said he wasn't watching chat in all this.

How can one be sure no offline "WR" video was overlayed and then cut to the live stream again?
