The default mental image of video compression involves unwanted video artifacts, like pixelation and blockiness in the image. This sells short, though, the complexity that actually goes into compressing video content. In particular, it overlooks a fascinating process called interframe, which involves keyframes and delta frames to intelligently compress content in a manner that is intended to go unnoticed.
This article describes this process in detail, while also giving best practices and ideal encoder settings that you can apply to your live streaming at IBM Cloud Video. Much of this specific advice relates to streaming due to adaptive bitrates.
Have you considered becoming a professional media server operator or user? Unsure of what technical skills you need? This is blog number three in our series on media server pros, and this time we’re digging further into the details of media server content (yes, video) for playback in media servers, based on recommendations from the fine people of the Media Server Professionals (Facebook) group.
