11/8/2023 0 Comments Advanced video codec frame count![]() ![]() Currently, there’s H.264, VP6, Windows Media and Sorenson Spark in the streaming space, with MPEG-2 dominating the DVD and Blu-ray spaces. There are still image codecs (like JPEG), audio codecs (like MP3) and more video codecs than you could shake a digital stick at. As the nifty capitalization in the previous sentence suggests, the term codec is a contraction of the two words encoder and decoder. CodecsĬodecs are compression technologies with two components an en coder to compress the file in your studio or office and a decoder to decode the file when played by the remove viewer. ![]() For this reason, in this introductory article on streaming media concepts, I define file related terms like codecs, bandwidth, frame rate, data rate and resolution, and then delivery options like streaming and progressive download. However, though many of us use streaming-related terms like data rate and bandwidth every day, there may be some residual lack of certainty as to what they precisely mean and why they are important. The ability to produce streaming media has suddenly become a critical skill set for many web producers. Streaming 101: The Basics – Codecs, Bandwidth, Data Rate and Resolution ![]() If you’re finding this article helpful, note that the author of this post now has a book out entitled.Streaming 101: The Basics – Codecs, Bandwidth, Data Rate and Resolution.Thanks for coming and we hope you find it useful. You’ll also learn how to use key Apple HLS creation and checking tools like Media File Segmenter and Variant Playlist Creator. ![]() 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). The book walks the reader through quality testing, basic encoding configurations, encoding with H.264, HEVC, and VP9, and and encoding for adaptive streaming. 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. This takes the guesswork out of most encoding decisions and allows readers to achieve the optimal quality/data rate tradeoff. 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.
