This means that terabytes or gigabytes of raw video content can be compressed into megabytes. 1. Compressed files contain fewer bits of data than uncompressed files. When an image is compressedin a camera or a computerless information is in the file, and the finer details of color, contrast, and sharpness are reduced. Video compression software examines the pixels in each frame of video and compresses them by bunching similar pixels together in large blocks. Codecs filter out additional data, such as frames of similar images, by grouping them into categories. Theyre algorithms that compile files by encoding the data they contain. When you request compression by using the COMPRESS= option, SAS considers the following information: The header information of the data set to determine how many variables are in the program data vector.
