HDCAM SR FAQ
Why another videotape format?
HDCAM-SR meets the production demand for higher bandwidth image capture and helps bridge the gap between acquisition and Digital Intermediate workflows by providing full bandwidth RGB for ingest to the process.
The fact that RGB images can now be stored real time in a cost effective and time efficient manner, will benefit the industry in general by opening many doors for higher quality composite effects, and film to tape archiving.
Is there a field unit for HDCAM-SR?
Yes - The SRW-1 will be available in the middle part of 2004. This unit will provide the same recording functions as the SRW-5000 but will not offer many of the studio deck features.
In addition to the same 440 Mbps record capability offered by the SRW-5000, the SRW-1 will also provide 2 times speed recording for the purposes of 3D stereo 422 recording. In this mode the unit will record two independent 422 signals at 440 Mbps with full error correction applied to both signals.
Additionally, the 2 times speed record mode will record RGB signals at 880 Mbps. This yields a compression ratio of approximately 2/1 in 4:4:4.
Will the SRW1 2 times speed recordings playback in the SRW-5000?
No - The SRW-5000 has only one playback and record speed.
How will I use an SRW1 880Mbps recording?
This high level of image capture in 4:4:4 recording is intended for digital intermediate ingest from an SRW1 playback to a system server. Stereoscopic 4:2:2 recordings will be either ingested in like fashion or recorded to two separate SRW-5000 decks for post.
How robust are these machines - what type of head life can I expect?
The tape transport used in HDCAM-SR is very similar to the ones used in HDCAM and Digital Betacam. These formats have proven reliability, and the design experience gained over the last twenty has been applied to HDCAM-SR. We anticipate the same reliability and performance that we have seen from the entire ½ inch family of VTRs with a projected head life of 3000 hours.
Does HDCAM-SR use the same tape as HDCAM?
No - A new formula tape has been created with metal particles that are approximately half the size of HDCAM. This allows for a much higher density recording layer that provides an additional 6 dB of signal level.
When are the new machines available?
The SRW-5000 is available and the accessories are due soon.
