AI in the film industry Artificial intelligence has now arrived in many areas of audio and image processing, even editing is already partially supported with AI.

As early as the 90s, people believed that AI would change and make everything easier, but the limitations imposed by the computing speed were simply too great. Today we find AI in numerous tools and applications, and more and more in the field of sound and image processing, and thus also...

What is Rec. 2020 really? When it comes to HDR, there is no getting around Rec. 2020 as the color space to be used, that is clear as far as it goes. It is also clear that there is no display that can actually reproduce this color space. So far nothing new. HDR-capable displays, such as consumer OLED TVs, can only display DCI-P3.

Embedding static metadata in HDR10 videos offers several advantages, but also disadvantages. Static metadata such as MaxCLL and MaxFALL can in some cases even degrade the image if you don't pay attention to certain points. One reason for this are so-called outliers.

As a result, the picture is darker and weaker than "planned". When analyzing the metadata, such outliers are often not recognized correctly. The reasons for this are very different. Today we look at one of the possibilities with...

(or: A journey into the wonderful world of colors) LUTs LUTs are great when they're done right. Ultimately, everything in the digital world is based on math, including color grading. All the better if you know and understand a few basic simple relationships.Let's take a look at some very simple models and calculations using the example of transforming from RGB to HEX and from RGB to HSL. HEX On the web, HEX is a very well-known and used format for defining colors. The name is derived from the term hexadecimal. HEX is used by us humans to shorten the binary...
