Delve into the nuances of photo and video editing with Metal, a framework from Next Generation GPU APIs. Right now, the demand for media editors is growing exponentially, with multiple applications needing some form of image processing, including messengers, social networks, marketplace, and banking applications. This book provides detailed guidelines for reimplementation instruments from one of the more popular photo and video editors.

Begin your journey by reviewing the rationale for using Metal, and an overview of the reasons why this this is the best performance solution. Rasterization is then covered to provide a basis for understanding how image editing in Metal works. Yoüll look at aspects of image processing such as rendering, image transformations, and working with textures. This knowledge then leads you to image editing, where it is applied to make basic color adjustments, shadows, blur, vignette, and color correction with LUT filters. These are fundamental aspects of any media editing software.

Layers make up the final section of the book, including different compositions and blend modes, both essential tools for any image editor. Yoüll conclude the journey with a look at video editing with Metal. Through hands-on projects in each chapter, you will learn how to apply these techniques directly in real-world scenarios, giving a great starting point to implement any kind of media processing in your own applications.
