PDF is the best format for storing and exchanging scanned documents. Unfortunately, PDFs can be difficult to modify. OCRmyPDF makes it easy to apply image processing and OCR to existing PDFs. Contents 1 ocrmypdf Documentation, Release 9.6.1 2 Contents CHAPTER 1 Introduction OCRmyPDF is a Python 3 application and library that adds OCR layers to PDFs. 1.1 About OCR Optical character recognition is technology that converts images of typed or handwritten text, such as in a scanned document, to computer text that can be selected, searched and copied. OCRmyPDF uses Tesseract, the best available open source OCR engine, to perform OCR. 1.2 About PDFs PDFs are page description files that attempts to preserve a layout exactly. They contain vector graphics that can contain raster objects such as scanned images. Because PDFs can contain multiple pages (unlike many image formats) and can contain fonts and text, it is a good formats for exchanging scanned documents.

(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.

A Comparison of Video Formats for Online Teaching Ross A
Contemporary Issues in Education Research – First Quarter 2017 Volume 10, Number 1 A Comparison Of Video Formats For Online Teaching Ross A. Malaga, Montclair State University, USA Nicole B. Koppel, Montclair State University, USA ABSTRACT The use of video to deliver content to students online has become increasingly popular. However, educators are often plagued with the question of which format to use to deliver asynchronous video material. Whether it is a College or University committing to a common video format or an individual instructor selecting the method that works best for his or her course, this research presents a comparison of various video formats that can be applied to online education and provides guidance in which one to select. Keywords: Online Teaching; Video Formats; Technology Acceptance Model INTRODUCTION istance learning is one of the most talked-about topics in higher education today. Online and hybrid (or blended) learning removes location and time-bound constraints of the traditional college classroom to a learning environment that can occur anytime or anywhere in a global environment. DAccording to research by the Online Learning Consortium, over 5 million students took an online course in the Fall 2014 semester. This represents an increase in online enrollment of over 3.9% in just one year. In 2014, 28% of higher education students took one or more courses online (Allen, I. E. and Seaman, J, 2016). With this incredible growth, albeit slower than the growth in previous years, institutions of higher education are continuing to increase their online course and program offerings. As such, institutions need to find easy to develop, easy to use, reliable, and reasonably priced technologies to deliver online content.
