Master Photo and Video Editing with Metal: A Practical Approach to Leveraging Metal Media Editing Software

GPU-Accelerated Photo and Video Editing on Apple Platforms 💻

Metal gives Apple developers direct access to the GPU, and this book shows how to use that power for real media-editing work. Bogdan Redkin and Victor Yaskevich take a practical route through the framework, starting with rendering fundamentals and building toward complete image and video processing pipelines. The focus stays on understanding what happens under the hood: shaders, pipelines, textures, layers, and the commands that turn data into visible results.

From Rasterization to Shader-Driven Effects

The opening sections establish the Metal rendering pipeline. Readers work through render pipeline states, shader functions, vertex assembly, coordinate spaces, transformations, matrix operations, and perspective projection. Textures and images enter the picture early enough to connect the theory with practical loading and display tasks. The book does not treat these topics as isolated theory; each concept supports the later editing effects.

Image Editing with Compute Shaders 🎨

Part II moves into image editing using compute shaders. The book covers basic color adjustments, including contrast, brightness, and saturation, then moves to vignettes, blur effects, and lookup-table color grading. The material explains how effects are structured, how compute grids and thread groups are dispatched, and how shader components combine. For developers building photo filters or custom image tools, this section provides a grounded path from simple adjustments to more advanced GPU effects.

Layers, Blend Modes, and Video 🎬

Multilayer rendering introduces image composition, layer transformations, alpha compositing, blending, and layer effects. The final part applies the same foundation to video: customizing video processing with AVFoundation, handling frames with Metal, and setting up video layers. The result is a coherent view of how photo and video editing features can share a common Metal-based architecture.

Who This Book Is For

This Apress title is aimed at iOS and macOS developers, graphics programmers, and technically inclined creators who want to implement media editing rather than rely only on high-level frameworks. Comfort with programming and a willingness to work through graphics concepts will help readers get the most from the material. If you want to understand how Metal can drive image and video effects from the GPU up, this book is a focused technical guide.
