Buy HD Digital Video Tapes for your Next Production Work
HD DV tapes (High Definition Digital Video Tapes) are designed for recording and playing back of digital signals rather than analog video signals. Launched in 1995, this tape format has become an ideal choice for videographers of today.
The video coding in DV tapes compress the recorded video on a frame-by-frame basis, while storing the audio uncompressed. The Digital Interface Format (DIF) is the basic unit of recorded data on DV tapes. The audio, video and metadata are packaged into 80-byte Digital Interface Format (DIF) blocks which are combined into a 150-block sequence. The DIF blocks can be stored as file formats like AVI (Audio Video Interleave), Quick Time and MXF (Material eXchange Format). A video frame in a DV tape is formed by 10 or 12 sequences, depending on scanning rate of video and audio contents. Once the video and audio signals get written to the tape, each sequence is identified as a complete track.
However, with the advancement of technology, Sony and Panasonic have introduced some latest versions of digital video tapes. Almost all the DV tapes use same compression system but differ in features like color rendition, robustness, editing functions and scanning pattern.
Take a look at some variants of HD DV tapes that are highly used by television production houses:
• DVCPRO tape: Introduced in the year 1995, this variation of DV was developed by Panasonic. It is highly used by broadcasting industries for news gathering and reporting process.
• DVCAM tape: This professional version of DV was launched by Sony 1996. It allows recording of Mini-DV footage over DVCAM tape and prevents audio synchronization drift which may occur when several generations of recorded copies are made by the users.
• DVCPRO50: This digital video format was introduced by Panasonic in the year 1997. It doubles the coded video data rate to 50 Mbit/s, thereby cutting recording time in half compared to DVCPRO tapes. It offers high quality recording of news and digital cinema and hence is a boon to the broadcasting houses.
