Convert DV to AVI

.dv

DV was created in 1995 as a digital format of video compression and magnetic video recording. With an 8-bit digital component video signal and a resolution of 720×576 pixels, data is transferred in the form of a DIF-sequence containing audio, video, and subcode data. The service area is used for the storage of time and date.

DV, DVCAM, and DVCPRO are Digital Video families with the same video encodings. Data in the DV format is into formats with each having 80-byte blocks. The blocks form the DV streams with each block having a 3-byte ID header that tells the block type and position in the DIF. Types of blocks are; Video Auxiliary Information (VAUX), Subcode, DIF sequence header, Video, and Audio. The blocks are in raw form as files (.dv or .dif extension) and put in formats such as MXF, AVI, and QuickTime.

AVI stands for Audio and Video Interleave. It has an extension written as .avi, and users use this same format to store audio and video on their PC, which was developed by Microsoft in 1992 for its Video for Windows project. It allows the simultaneous playback by keeping video and audio into a single file. The simple architecture of .avi format will enable it to run on various operating systems such as Windows, Mac, Linux, Unix. It is supported by multiple web players as well.

AVI format uses Resource Interchange File Format (RIFF) support, where the real data is stored into chunks, and each chunk gets recognized by a FourCC tag. Out of these individual chunks, the first one can be recognized by the hdrl tag, and it can decode the chunk containing metadata for the video. The second chunk gets identified by the movi tag, and it includes the actual audio and visual data which makes up the AVI movie. It uses less compression rather than the MOV and MPEG file formats.
