Convert m4v to viff

What is the difference between .m4v and .viff?

Description: The M4V file format is a video container format developed by Apple and is very similar to the MP4 format, with the primary difference being the optional Apple Digital Rights Management (DRM) protection. M4V files are commonly used for TV episodes, movies, and music videos in the iTunes Store. These files can be played on Apple devices such as iPhones, iPads, and iPods, as well as on PCs using iTunes or other compatible media players.; The Visualization Image File Format (VIFF) is a specialized file format designed for storing image data. It is primarily used in scientific and technical applications where complex visualization of multi-dimensional data is required. VIFF files can store various types of data including grayscale, color, and multi-spectral images, making them suitable for tasks such as image processing, medical imaging, and remote sensing. This format supports a range of metadata, allowing for the inclusion of information about the image data, such as dimensions and color.
