Thus, various encoder ence model for MPEG-4 Audio Lossless Coding (ALS), attaining implementations are possible, offering a certain range in terms of working draft status in July 2003. The encoder is based on linear efficiency and complexity. This section gives an overview of the prediction, which enables high compression even with moderate basic encoder and decoder functionality. complexity, while the corresponding decoder is straightforward. The paper describes the basic elements of the codec, points out 2.1. Encoder Overview envisaged applications, and gives an outline of the standardization process. The MPEG-4 ALS encoder (Figure 1) typically consists of these main building blocks: • 1. INTRODUCTION Buffer: Stores one audio frame. A frame is divided into blocks of samples, typically one for each channel. Lossless audio coding enables the compression of digital audio • Coefficients Estimation and Quantization: Estimates (and data without any loss in quality due to a perfect reconstruction quantizes) the optimum predictor coefficients for each of the original signal. -
Industry Standard Softwares
INDUSTRY STANDARD SOFTWARES used in the creation, editing and post-production process within four different areas of Creative Media RESEARCH BY: MELANIE-JO MANGANI 1. PHOTO MANIPULATION SOFTWARES Photo manipulation softwares are applications that can be used to edit photos. Examples are: Photoshop, Lightroom, Affinity Photo, Pixlr and Gimp. Here is an explanation about one of them: PHOTOSHOP You want to make your photos as amazing as your memories? So, use photoshop! That is the main describtion used by Adobe for this software. Photoshop is a sofware used for professional photo editing created by Adobe Systems company. You can work on photoshop, both on Windows and Mac opertaing systems. The purpose of this software is to help us edit any kind of image – manipulate, crop, resize and colour correcting photos (only digital). Who should use photoshop? This software should be used by professional photographers and graphic designers. Technical Specifications / Technical Requirments Windows: 1.6GHz or faster processor Microsoft Windows 7/8/10 (64bit) 4GB of RAM 5GB of available space on hard-disk 1024x768 display resolution Microsoft Directx9 or 10 compatible display driver Mac OS: 64bit multicore intel processor Max Osx v10.10 or v10.11 6GB of RAM 5GB available harddisk space 1024x768 display resolution Advantantages of photoshop: • An new easy way how to organize photos: Photoshop let you import your photos quickly or even videos and then everything will be organized on the software itself. This will help you find the items more easy. • Quick Editing: Photoshop have the fascility of one-click edit. This will help the user to edit a photo with just one click. -

(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. -
