![]() ![]() Bitrate – Usually measured in kbit/s, is a metric that characterises just how much data each second of video takes to store.In addition to these distinctions, there are other factors to consider, like bitrate, I-frame intervals, and “efficiency,” all of which are relevant to the discussion: This is the type of codec most relevant to streaming and online media. They treat frame sequences in large chunks, converting most of the frames into instructions that tell the video player where to shift pixels rather than displaying a new image. Interframe codecs compress both the individual images and the temporal data to radically reduce file sizes.These codecs aren’t usually used in streaming because of the large file sizes. Intraframe codecs are preferred in video production because of the low computational demand and the higher image quality compared to Interframe Codecs. File sizes for these codecs are typically much larger. Intraframe codecs treat each frame as a discrete piece of data, and any compression is done the same way it would be done to a still image, frame by frame.Sometimes erroneously referred to as “lossless” and “lossy” codecs Video Codecs are generally split into two separate categories. If you’re familiar with the nuts and bolts of video encoding you can skip this section, but if not I recommend you at least skim through it. Understanding Stadia Means Understanding Video Codecsīefore we can talk about Stadia, we need to provide some basic information on video codecs as a foundation for what we’ll be discussing later. There’s a lot that can be learned about Stadia by examining the resources required to deliver 1:1 on demand streaming to thousands of clients simultaneously, so we’ve put together some information and qualitative analyses that we think offer a new perspective on how Google’s game streaming service will work. Of course, a company as large as Google has the resources to make it happen, but the computational load of that process is still significant, and there’s no magic wand that can wave it away. #DATAMOSHING WITH FFMPEGX FREE#This site will always be free of ads and sponsored content.Īny twitch streamer or video editor can tell you that encoding high bitrate video in real time is a nontrivial challenge, even on current hardware. ![]() There’s also been some discussion of video quality and latency built into systems like Stadia, but surprisingly, no one seems willing or able to go into detail about another key element: the computational cost of encoding.Ĭonsider supporting us on Patreon if you value independent tech news and research. There’s been a lot of speculation in the press about the bandwidth and connection requirements of Stadia, Google’s upcoming game streaming service.Ĭriticisms usually arrive at metered connections or bad infrastructure in rural areas for key talking points. ![]()
