Detailed explanation-1: -Compressed data files occupy less disk space than uncompressed data files. Files compressed with ZCOMPRESSED occupy the least disk space. Compressed files may take more or less time to open and save, depending on the file size and system configuration. Extra time is needed to de-compress and compress the files.
Detailed explanation-2: -Lossy compression is the traditional and most commonly used type of compression for reducing file size. It’s the type of compression where the size of the original video file is reduced by removing parts of the original video deemed unnecessary.
Detailed explanation-3: -TIFF files are significantly larger than their JPEG counterparts, and can be either uncompressed or compressed using lossless compression. Unlike JPEG, TIFF files can have a bit depth of either 16-bits per channel or 8-bits per channel, and multiple layered images can be stored in a single TIFF file.
