This document describes in detail a set of resolutions, bitrates and settings used for high quality H. Video encoding is a game of tradeoffs, and these settings represent a balance which is very good, and difficult to improve upon. Familiarity with basic video encoding terms and technology is assumed when reading this document, and an understanding of the nitty gritty details might also be helpful. Resolutions Bitrates. We provide video files at 7 different standard widescreen resolutions. SD or NTSC widescreen5. Detailed notes regarding the resolutions, bitrates and settings used for highquality H. The Internet Archive. Does the Archive issue grants No although we promote the development of other Internet libraries through online discussion. Live online video is exploding in popularity, so read these expert tips to get perfect results when moving an event from the camera to the viewers screen. PAL widescreen7. HD1. Full HDEncoding at such a wide range of resolutions is based on the assumption a web video embedding mechanism will be used that is capable of detecting the viewers Internet connection speed and choosing the appropriate video file based on that link speed, along with the screen size and playback capabilities of the browser  thus supplying each different viewer with the best resolution and bitrate heshe can use. Simpler video embedding may also be used, of course, right down to a basic HTML5 lt video tag pointing to a single version of the video, but the whole point of encoding at a variety of resolutions and bitrates is intended for an intelligent embedding mechanism to make sensible use of those many different versions, supplying high quality HD video to those viewers with fast enough Internet links, while falling back gradually for viewers with increasingly slower links. For each resolution, we use a bitrate which is the lowest sensible 6. Internet link speed see below that still achieves very good visual quality, with no major visible compression artifacts. SMPTE 421M, informally known as VC1, is a video coding format. It was initially developed as the proprietary video format Windows Media Video 9 by Microsoft in 2003.

Many tools will just base their assumptions on the bitrate and encoder. MStar T12 UHD TV SOC Platform Incorporates Fraunhofer MPEGH TV Audio System Decoding Capabilities.

Just like saving a still image for use on a website, we put quality first and only compress as much as possible without introducing any noticeable degradation hopefully. If that means using a higher bitrate for a given resolution than some other websites, then so be it  the net can take it, and bandwidth is less and less of a problem every day. Its unwise to push bitrates too low and risk delivering a blurry, unprofessional video, which other sites such as You. Tube routinely do. For most of the resolutions we also provide a higher quality HQ version encoded at a somewhat higher bitrate, for the benefit of users with sufficiently fast Internet links. The visual differences from the normal, very good quality version to the HQ version are generally quite small, such as less blur during rapid motion, less risk of banding in dark scenes, and less risk of crystallizing during difficult fades. Nonetheless, we might as well take advantage of the users link speed for improved quality from fewer compression artifacts, assuming the users link is not fast enough to get up to the next higher resolution, which would be a significant step up in general sharpness and clarity. Finally, we also encode a superbit, ultimate quality version at full HD 1. Blu ray. The bitrate chosen is 2. Mbps, which is a safe 8. H. 2. 64 level 4. The superbit version should be almost lossless, practically indistinguishable from the original master a transparent encoding, as its known. It acts both as the best local playback non web version and as a long term master for future transcoding eg You. Tube uploads, burning to DVDBlu ray, re encoding with future codecs etc. Audio is encoded at 4. Hz in AAC format, mono at 6. The lower resolutions all use identical audio settings to allow switching cleanly between them in an adaptive streaming scenario without any audible pops. The 1. 28 kbps versions are a stereo equivalent of the same settings. Switching from mono to stereo with the same settings should be almost seamless, and should only happen once in most cases, since a user is unlikely to need to switch back down if their link is ever over 5 Mbps making that changeover at a lower speed, such as 3 or 4 Mbps, would be more problematic  the faster the link, the more likely it is to be well above what we need. The superbit, ultimate quality version uses the maximum possible AAC bitrate. The exact bitrates chosen are. Name. Resolution. LinkMbpsBitrateMbpsVideokbpsAudiokbps2.

Internet link speed 1, 1. Mbps etc in order to make full but safe use of that common connection speed. Unlike still images, where we want the smallest good looking file to have the web page finish loading as quickly as possible, for video we only care that it downloads fast enough to play. Downloading a video faster than we need for playback doesnt make any difference to the end user, but using more of his link speed to improve the quality does, so we actually want to avoid under shooting the users available bandwidth for video, and increase the sizebitrate as much as is safely possible. On the other hand, pushing too hard and using too much of the users link speed might result in pausing for buffering, which is much worse from an end users point of view than slightly lower quality. So, we start with bitrates which match the most common link speeds, then leave 2. ADSL and contention during busy times. Assuming 8. 0 of peak link performance has long been a good real world guide, and US FCC data from 2. We then only use 8. Again, experience shows 8. Netflix seems to use a conservative. Internet link speeds continue to rise rapidly, so while our chosen bitrates are higher than some other video websites, for qualitys sake, theyre still quite reasonable. Based on Akamai data from 2. Mbps in Japan, South Korea and Hong Kong, 4. Mbps in the USA and Canada, somewhere around 4 Mbps in Western Europe, 2. Mbps in Australia and 2. Mbps in Russia. Even 3. G cellphone networking is around 2 Mbps on average, although its highly variable. The average American can therefore already view the 7. Australian or Russian the 4. The average in. such statistics is skewed by the high speeds, of course, since its an exponential curve, but even so, about one third of Internet connections in modern countries are over 5 Mbps real world downloading speed, which is enough for the 7. HQ versions, and 7. Mbps and therefore can definitely view the 4. Even in Australia, where broadband speed is more uneven and the average lags behind most modern countries, government statistics from 2. Mbps link speed, and 4. Mbps link speed. Its useful to compare our chosen video bitrates with the major online video providers. All use H. 2. 64 as their preferred video codec. The bitrates below have been personally verified for i.
