| prince karak | Re: dv formats explained Don’t worry I will explain you more about DV Formats, so that you can go through it and have idea about it. The DV Formats is for storing digital video which known as Blue Book, was standardized within the IEC 61834 family of standards which define common features such as physical videocassettes, recording modulation method, magnetization etc. Digital Interface Format The audio, video, and metadata are packaged into 80-byte Digital Interface Format (DIF) blocks which are multiplexed into a 150-block sequence. DIF blocks are the basic units of DV streams and can be stored as computer files in raw form or wrapped in such file formats as Audio Video Interleave (AVI), QuickTime (QT) and Material Exchange Format (MXF). One video frame is formed from either 10 or 12 such sequences, depending on scanning rate, which results in a data rate of about 25 Mbit/s for video, and an additional 1.5 Mbit/s for audio. When written to tape, each sequence corresponds to one complete track. This means that the sound may be +/- ⅓ frame out of sync with the video. However, this is the maximum drift of the audio/video synchronization; it is not compounded throughout the recording. Variants DVCPRO DVCAM DVCPRO50 DVCPRO Progressive DVCPRO HD |
