BVM-E Series Digital Cinema Features

The BVM-E Series – comprising BVM-E250A and BVM-E170A master monitors – offers digital cinema features which are indispensable and ideal for

high-quality creative digital cinema onset and post-production workflow.

2K (2048 x 1080, RGB/XYZ) Input

BVM-E250A and BVM-E170A master monitors are capable of 2K (2048 x 1080 resolution,

RGB/XYZ) input. The 2K signal is displayed in two ways – as a full 2K image scaled into

a full-HD (1920 x 1080) screen, or as a 2K native display with an image-slide function.

2048 Image-slide

The 2048 Image-slide function allows 2K resolution

(2048 x 1080 pixels) images to be mapped,

pixel-to-pixel, on the full-HD (1920 x 1080 pixels)

panel without picture degradation. When the user

needs to view the left or right edge of the picture

frame, they can scroll the image in a horizontal

direction.

S-LOG Gamma

S-LOG gamma is a technique used in Sony’s digital cinematography cameras

that allows the full latitude of the camera imager to be maintained throughout

the production chain. Unlike conventional systems, in which highlight contrast

is compressed, S-LOG Gamma logarithmically converts the video signal using

characteristics similar to film negatives.

This keeps the camera imager dynamic range intact, even in extreme highlight areas.

Two display modes are offered:

1) S-LOG Full

This mode displays the full dynamic range of the video signal captured from Sony’s

digital cinematography cameras.

2) S-LOG Standard

This mode displays image exposure levels at the lower part of the S-LOG gamma

signal dynamic range, allowing image areas of regular brightness to be viewed

clearly. Higher exposure levels are clipped in this mode.

Gamut Error Display

This function detects irregular signal input. When

an irregular signal is detected, these master

monitors indicate this with a zebra pattern over

the relevant area of the picture.

Gamut Error Display is a convenient feature that

instantly alerts viewers to such signals without

requiring the use of a waveform monitor.

ASC CDL and User LUT Functions

BVM-E Series monitors support the ASC CDL (American Society of Cinematographers

Color Decision List) and User LUT (Look-up Table) to emulate color grading.

Live images from camera onset can be altered after importing an ASC CDL format,

and/or previewed using a film print emulation applied to the monitor using Look

Creation Workflow.*

Furthermore, once ASC CDL and User LUT data are created, all information*

can be

saved to Memory Stick media*

and loaded onto the monitor from the BKM-16R*

controller. Up to five items of ASC CDL and User LUT data can be imported to BVM-E

Series monitors, so users can easily compare different color grading (see Look

Application Workflow).

These features help with creative decision making and improve workflow between

onset and post-production.

*1 Requires third-party software supporting the BVM-E ASC CDL and User LUT functions.

*2 Up to 1,000 data items.

*3 Can use a Memory Stick, Memory Stick PRO™, Memory Stick Duo™, Memory Stick PRO Duo™, or (with optional

adaptor) Memory Stick Micro™.

*4 Requires the latest version of the BKM-16R with a product code suffix /7 or later.
