Description: M4V is a video container that stores audio and video data used for iTunes files. Files of this type may be protected from illegal viewing and copying with Apple FairPlay DRM. In this case audio or video files should be bought in iTunes store. Not protected files can be viewed almost in any modern player because the format is based on MPEG-4 structure.; The VDA file format, short for Targa Bitmap Image File, is a variant of the TGA file format (Truevision Advanced Raster Graphics Adapter) used for storing digital images. Developed by Truevision Inc., VDA files are raster graphics files that support various color depths, ranging from 1 to 32 bits per pixel, which includes support for alpha channels and compression. This format is designed to be highly flexible and is capable of storing high-quality images used in video editing and animations.
