(A/V Codecs) REDCODE RAW (.R3D) ARRIRAW
What is a Codec? Codec is a portmanteau of either "Compressor-Decompressor" or "Coder-Decoder," which describes a device or program capable of performing transformations on a data stream or signal. Codecs encode a stream or signal for transmission, storage or encryption and decode it for viewing or editing. Codecs are often used in videoconferencing and streaming media solutions. A video codec converts analog video signals from a video camera into digital signals for transmission. It then converts the digital signals back to analog for display. An audio codec converts analog audio signals from a microphone into digital signals for transmission. It then converts the digital signals back to analog for playing. The raw encoded form of audio and video data is often called essence, to distinguish it from the metadata information that together make up the information content of the stream and any "wrapper" data that is then added to aid access to or improve the robustness of the stream. Most codecs are lossy, in order to get a reasonably small file size. There are lossless codecs as well, but for most purposes the almost imperceptible increase in quality is not worth the considerable increase in data size. The main exception is if the data will undergo more processing in the future, in which case the repeated lossy encoding would damage the eventual quality too much. Many multimedia data streams need to contain both audio and video data, and often some form of metadata that permits synchronization of the audio and video. Each of these three streams may be handled by different programs, processes, or hardware; but for the multimedia data stream to be useful in stored or transmitted form, they must be encapsulated together in a container format. -

Recommended File Formats for Long-Term Archiving and for Web Dissemination in Phaidra
Recommended file formats for long-term archiving and for web dissemination in Phaidra Edited by Gianluca Drago May 2019 License: https://creativecommons.org/licenses/by-nc-sa/4.0/ Premise This document is intended to provide an overview of the file formats to be used depending on two possible destinations of the digital document: long-term archiving uploading to Phaidra and subsequent web dissemination When the document uploaded to Phaidra is also the only saved file, the two destinations end up coinciding, but in general one will probably want to produce two different files, in two different formats, so as to meet the differences in requirements and use in the final destinations. In the following tables, the recommendations for long-term archiving are distinct from those for dissemination in Phaidra. There are no absolute criteria for choosing the file format. The choice is always dependent on different evaluations that the person who is carrying out the archiving will have to make on a case by case basis and will often result in a compromise between the best achievable quality and the limits imposed by the costs of production, processing and storage of files, as well as, for the preceding, by the opportunity of a conversion to a new format. 1 This choice is particularly significant from the perspective of long-term archiving, for which a quality that respects the authenticity and integrity of the original document and a format that guarantees long-term access to data are desirable. This document should be seen more as an aid to the reasoned choice of the person carrying out the archiving than as a list of guidelines to be followed to the letter. -

Which Image Format
CASE STUDY Which Image Format PNG PNG (Portable Network Graphics), an extensible file format for the lossless, portable, well-compressed storage of raster images. PNG provides a patent-free replacement for GIF and can also replace many common uses of TIFF. Indexed-color, gray scale, and true color images are supported, plus an optional alpha channel. Sample depths range from 1 to 16 bits. However, the format is not widely supported in common image programs. AVI AVI stands for Audio Video Interleave and is currently the most common file format for storing audio/video data on the PC. AVI’s are 8-bit per image plane. This file format conforms to the Microsoft Windows Resource Interchange File Format (RIFF) specification, which makes it convenient for sharing the image sequence between computers. AVI files (which typically end in the .avi extension) require a specific player that supports. RAW A RAW image format contains minimally processed data from the image sensor. RAW literally means unprocessed or uncooked. RAW images must be processed and converted to RGB format if it is a color image. Photron however, does not limit RAW as a unprocessed image. The “Bayer” check box must be selected to save the RAW image as an unprocessed image. RAW images have 8-bits per image plane. RAWW A RAWW image format contains minimally processed data from the image sensor. RAWW images must be processed and converted to RGB format if it is a color image. Photron however, does not limit RAWW as a unprocessed image. The “Bayer” check box must be selected to save the RAWW image as an unprocessed image. -
Digital Mathematics Library Report of the Technical Standards Working Group
1 Digital Mathematics Library Report of the Technical Standards Working Group Date May 18, 2003 Thierry Bouche, Ulf Rehmann Cochairs: Thierry Bouche Grenoble [email protected] Ulf Rehmann Bielefeld [email protected] Members: Pierre Berard [email protected] Jon Borwein [email protected] Keith Dennis [email protected] Michael Doob [email protected] Contents 1 Scanning Quality 2 2 Archiving Formats 2 3 File Name and URL Conventions 3 4 Delivery Formats 4 5 Download Units 5 6 Server Techniques 5 7 Further recommendations 6 8 Remarks 8 References 8 This document gives technical recommendations to ensure the integration of digitized mathematical documents in a uniform “Digital Mathematics Library” (DML). Since the digitized documents will be produced by various projects, possibly ap- plying different methods and technologies, these recommendations define general technical standards in order to make the DML as a whole easily accessible, usable, maintainable, and sustainable. A digitization project requires several procedures. The most critical tasks are the scanning and archiving processes, which are substantial for the quality and longevity of the data to be preserved. The scanning part requires most of the work, it cannot easily be repeated and should therefore be performed with greatest care. 2 Thierry Bouche, Ulf Rehmann Other tasks, like enhancing the data by OCR layers1, annotations, metadata, and web links, could be either postponed or possibly redone, if later on more advanced technology becomes available. The actual file formats or implementations mentioned here are presented as ex- amples, which, at the time of this writing, can be used in order to achieve the proposed standards. -

FACTFILE: GCSE DIGITAL TECHNOLOGY Unit 1 – DIGITAL DATA
FACTFILE: GCSE DIGITAL TECHNOLOGY Unit 1 – DIGITAL DATA Fact File 4: Portability Learning Outcomes Students should be able to: • demonstrate understanding of data portability and the following file formats that support it: jpeg, tiff, png, pict, gif, txt, csv, rtf, mp3, mp4, midi, mpeg, avi, pdf, wav and wma. • demonstrate understanding of the need for data compression. The Need For Data Compression Compression means reducing the storage requirements of a file by following one or more compression algorithms. LOSSLESS compression enables the original file to be fully restored to its original state. LOSSY compression involves discarding some data as part of the overall compression process in such a way that the data can never be reinstated. Files that demand high volumes of storage also require high bandwidth communication links in order for transmission to be completed within an acceptable time frame. Compression is used to reduce the: • VOLUME of storage required on storage DEVICES, enabling larger quantities of data to fit into the same amount of storage space • BANDWIDTH required to transfer multimedia files across COMMUNICATION LINKS (locally, nationally and globally) Without compression: • Very high VOLUMES of storage would be required, occupying more physical space and slowing down retrieval/save times • The available BANDWIDTH on most local and global networks would not cope with the volumes of data being sent, disrupting communication services (leading to e.g. lagging video streaming) Of course, there will be a price to pay for the benefits of compression, i.e. time will have to be set aside to compress and decompress the files as they are moved in and out of storage or across communication links. -
Creating Content for Ipod + Itunes
Apple Education Creating Content for iPod + iTunes This guide provides information about the file formats you can use when creating content compatible with iTunes and iPod. This guide also covers using and editing metadata. To prepare for creating content, you should know a few basics about file formats and metadata. Knowing about file formats will guide you in choosing the correct format for your material based on your needs and the content. Knowing how to use metadata will help you provide your audience with information about your content. In addition, metadata makes browsing and searching easier. This guide also includes recommended tools for creating content. Understanding File Formats To create and distribute materials for playback on iPod and in iTunes, you need to get the materials (primarily audio or video) into compatible file formats. Understanding file formats and how they compare with each other will help you decide the best way to prepare your materials. Apple recommends using the following file formats for iPod and iTunes content: • AAC (Advanced Audio Coding) for audio content AAC is a state-of-the-art, open (not proprietary) format. It is the audio format of choice for Internet, wireless, and digital broadcast arenas. AAC provides audio encoding that compresses much more efficiently than older formats, yet delivers quality rivaling that of uncompressed CD audio. • H.264 for video content H.264 uses the latest innovations in video compression technology to provide incredible video quality from the smallest amount of video data. This means you see crisp, clear video in much smaller files, saving you bandwidth and storage costs over previous generations of video codecs. -
