Pioneer PRV-9000 - Manual (Page 3)

Can the PRV-9000 be set to record in multiple bit rates in DVD-Video
format?
Yes, in DVD-Video format the PRV-9000 recorder has two MPEG2 CBR video
encoding bit rate settings. Mode #1 (V1) is 9.78 Mbps and allows one hour of
recorded video on a single-sided 4.7Gbyte DVD-R or DVD-RW disc. Mode #2
(V2) is 5.11 Mbps and allows two hours of recorded video on a single-sided
4.7Gbyte DVD-R or DVD-RW disc.
You can change the DVD-Video format bit rate setting for each record session.
However, you cannot use more than one bit rate setting in the same record
session
What is the pixel resolution of the video recorded in DVD-Video format?
The pixel resolution of V1 mode (9.78 Mbps) is 720x480.
The pixel resolution of V2 mode (5.11 Mbps) is 720x480.
How is the audio encoded in DVD-Video format?
The PRV-9000 can accept two channels of unbalanced audio. This audio is
encoded as Dolby Digital (AC3) 2-channel audio (16bit-48kHz-256kbps) for both
DVD-Video bit rate settings.
Can the PRV-9000 be set to record in multiple bit rates in VR format?
Yes, in VR format the PRV-9000 recorder can be set to one of one of 32 video
encoding bit rates. The highest quality setting is 10.08 Mbps and allows for one
hour of recorded video on a single-sided 4.7Gbyte DVD-RW disc. The lowest
quality setting is 1.73Mbps and allows for six hours of recorded video on a single-
sided 4.7Gbyte DVD-RW disc.
You can change the VR format bit rate setting for each record session. However,
you cannot use more than one bit rate setting in the same record session
Note: When using the DV IEEE-1394 video input you cannot set the VR bit rate
below 2.60Mbps.
What video compression attributes are applied in VR format?
All but the lowest six VR bit rates settings use MPEG2 compression. The lowest
six VR format settings utilize MPEG1. Also, depending on the bit rate selected
either VBR or CBR is applied to offer the best possible quality video and audio
signal at the selected bit rate setting
.
What is the pixel resolution of the video recorded in VR format?
The pixel resolution of video recorded in VR format differs based on video bit rate
setting selected for that record session
. The highest bit rate settings, from one
hour to two-hour recording modes, offer 720x480 pixel resolution.
