Been trying to figure out why I'm so obsessed with this story. I think it's because it symbolizes how this administration disregards expertise, whether that's scientists, historians, engineers, public health officials, electricians, plumbers, everybody. It's all about the grift.
A few seconds later, this shot has a bright glowing effect. In the our release version (left), the glow is around 99% brightness, nearly the maximum possible. But on the right it's now clipped, which is what happens when you try and exceed the video limit.
If we adjusted our newly released CC (left) to this new example brightness, it would look more like what's on the right. This image may look nice an eye catching, but there's a problem...
But how do you know how much leveling you should do? It isn't always obvious. Let's say for example we wanted our levels to match the source material. In these examples, Roshi's beard is around 95% brightness.
Clipping is, of course, generally bad. Notice how not only are the eyes blown out, but the glow around the eyes and pupil details look worse.
This is why leveling can be a dangerous procedure when done hastily or without consideration of the source material.
You can measure the levels of video objectively to ensure your results are consistent. The brightness of a section of video can range from 0% (totally dark) to 100% (completely bright). In the early example, Roshi's beard goes from 70% to about 88%.
