Beyond H.264

These provide the best, easily consumable, compression ratios and as such became the format of choice for mobile device designers and manufacturers. While H.264 does a very efficient job of compressing video, making larger sizes and higher quality possible at lower bit rates than previous formats, there’s always room for improvement. That’s where H.265, or HEVC (High Efficiency Video Coding), comes in. Continue reading
