Descriere & specificații

Video Encoding by the Numbers teaches you to optimize the quality and efficiency of your streaming video by objectively detailing the impact of critical configuration options with industry-standard quality metrics like PSNR and SSIMplus. This takes the guesswork out of most encoding decisions and allows readers to achieve the optimal quality/data rate tradeoff. Since all videos encode differently, the tests detailed in the book involve eight different videos, including movie footage, animations, talking head footage, a music video, and PowerPoint and Camtasia-based videos. The book walks the reader through quality testing, basic encoding configurations, encoding with H.264, HEVC, and VP9, and and encoding for adaptive streaming. When appropriate, the chapters conclude with a section detailing how to configure the options discussed with FFmpeg, a preferred tool for high-volume video producers, including packaging into HLS and DASH formats (the latter with MP4Box). You'll also learn how to use key Apple HLS creation and checking tools like Media File Segmenter and Variant Playlist Creator. Here's a chapter-by-chapter description. Chapter 1: Technology Fundamentals. Encoding basics like codecs and container formats for newbies, or for a quick refresher for advanced users. Chapter 2: Basic File Parameters. File parameters like data rate, resolution, frame rate, and bits-per-pixel defined at a high level. Chapter 3: Essential Tools. Identifies the tools you'll need to deliver file
