✜ 24p/30p Progressive Scan Modes
In these modes, the 1080p image captured by the 3
ClearVid CMOS Sensor system is also recorded as an
interlaced signal by dividing each frame into two fields.
This enables compatibility with current editing and
monitoring equipment that only accept interlace signals,
while maintaining the quality of the 1080p image.
When using the “24p scan”setting,captured images are
recorded as 60i through means of 2-3 pull-down.
Progressive scan modes are suitable for feature films,
documentaries,and music videos, which have to be
recorded as interlaced video for viewing on interlaced
monitors,but want to offer a “progressive look”to their
motion.
It is also possible to edit footage recorded in the “24p
scan”mode as progressive material.
NLE software that is compatible with the “24p scan”
mode can remove the 2-3 pull-down,then edit the
footage as 24p material.*

For 30p,most NLE software can output the edited timeline
in progressive format by merging odd and even fields.
*5 When 24p editing is needed with the “24p scan”mode,be sure to
select the “24A”setting in the “Scan Type”menu instead of the “24”
setting. This setting records the 2-3 pull-down identification data in the
HDV stream,so that compatible NLE software knows when to remove
the 2-3 pull-down cadences. In the 24A setting,interruptions in time
code and video may appear between recordings when viewed on an
HDV device. There is no “24A”setting in DVCAM and DV modes.

24p/30p HDV Native Progressive Recording Modes
The HVR-Z7U and HVR-S270U camcorders newly feature
24p/30p HDV native progressive recording modes.
The 3 ClearVid CMOS Sensor system and EIP create true
1080p images,which can then be recorded as
progressive signals by the HVR-Z7U and HVR-S270U
camcorders in HDV format.
The progressive HDV stream can be output from an i.LINK
connector and used for progressive editing with
compatible NLE software.
Native progressive recording modes are suitable for
output to film, CG composition,viewing on a progressive
monitor,or as an Internet movie.
Note: interlaced video is output from connectors other than i.LINK
The HVR-Z7U and HVR-S270U have two types of progressive shooting modes.
