免费在线 DV 转 M4V 转换器

DV is a digital format of magnetic video recording and a type of video compression developed by the major video equipment manufacturers in 1995. The DV format uses an 8-bit digital component video signal with a resolution of 720x576 pixels. Data transfer is made in the form of a DIF-sequence that contains video, audio and subcode data. Date and time are recorded in the service area.

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.
