Sony HVR-S270E, HVR-Z7E 25p HDV Native Progressive Recording Modes, 25p Progressive Scan Mode

Selectable Progressive Modes

The HVR-Z7E and HVR-S270E have two types of progressive shooting modes.

✜ 25p HDV Native Progressive Recording Modes

The HVR-Z7E and HVR-S270E camcorders newly feature a 25p HDV native progressive recording mode.

The 3 ClearVid CMOS Sensor system and EIP create true 1080p images, which can then be recorded as a progressive signal by the HVR-Z7E and HVR-S270E 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.

The native progressive recording mode is 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

✜25p Progressive Scan Mode

In this mode, 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.

The progressive scan mode is 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 “25p scan” mode as progressive material.

Most NLE software can output the edited timeline in progressive format by merging odd and even fields.
