M4V to AIFF converter
M4V is a video file format developed by Apple for use with its iTunes Store. It is based on the MP4 container format, and is typically used for video files protected with DRM. M4V files can have video and audio streams encoded using the MPEG-4 codec, and may also contain subtitles and other data.
If an M4V file does not contain a DRM-protected version of the video, it can be converted to other formats such as AVI or MOV using a suitable media conversion tool. If an M4V file does contain a DRM-protected version of the video, it cannot be converted into other formats without first removing the copyright protection.
The Audio Interchange File Format (AIFF) is a file format for storing high-quality audio data. It was developed by Apple Inc. in 1987 and is used commonly in the Mac OS operating system and its associated applications, though it can be found on other platforms as well. An AIFF file can store many different types of audio data, including samples taken from analog sources such as vinyl records and standard CD-quality audio.
AIFF files are uncompressed, making them larger than lossy compressed formats like MP3 and AAC -- but also providing better audio quality overall. Additionally, AIFF supports metadata tags like artist name and track title, allowing audio players to quickly identify the audio file's contents. While less common today than MP3 and other formats, AIFF still enjoys a following among audiophiles, musicians, and other audio professionals.
