This section is to help you understand codecs, video file formats, and how these formats are used in the day-to-day multimedia application.
Codecs
Short for compressor/decompressor, codecs are the engines that power the software applications that compress video files. Moyea is offering the codec of MFZ0 for our customers.
After you capture your video footage, the first step to delivering the video content is to compress it. In order to compress properly, it is important to understand how a codec works by explaining some basic compression concepts.
Compression is like making orange juice concentrate. Fresh oranges go in one end and concentrate comes out the other. The concentrated orange juice takes up less space, is easier to distribute, and can be easily reconstituted by the consumer.
One second of uncompressed video is roughly 30 MB. It is expensive to store, manage and deliver large amounts of data. Codecs help solve this problem by compressing video to smaller, more manageable sizes while still maintaining quality. The smaller files require less hard disk space, less memory to run, and less bandwidth to play over networks or the Internet.Video File Formats
A file extension is a generally a three letter suffix to a file name that follows a period. In the file sales.mov, sales is the file name and .mov is the extension. The extension tells the operating system which program to use to interpret the file.Advanced Streaming Format (ASF)
Stands for Advanced Streaming Format. stores audio and video information, and it is specially designed to run on networks like the Internet. ASP is a highly flexible and compressed format that contains streaming audio, video, slide shows, and synchronized events. When you use ASF files, content is delivered to you as a continuous flow of data. When an AVI file is compressed and converted to an ASF file, the file begins playing after only a few seconds.
Advanced Stream Redirector (ASX)
Advanced Stream Redirector files are text files used for redirection to MS Windows Media Player ASF files. These files contain media and server information but no actual video or audio. ASX files can be distributed as attachments or links. When you open an ASX file, the file opens the referenced movie in your media player, making it appear as though the entire file has been downloaded.
Audio Video Interleaved (AVI)
Audio Video Interleaved is a bitmap-based format for the Windows platform defined by Microsoft. It is the most common format
