Image analysis

A large variety of scopes

 

Dimensionables, with free positioning on the main screen or grouped on a second screen, scopes are automatically adapted to the image color space.

CIE Chromaticity diagram

 

This diagram allows you to see how the color is distributed within the boundaries of the color space.

The boundaries of the chosen Mastering Display and Safe Gamut can be added for a better control.

 

Waveform

 

The Waveform is used to measure and display the level of the brightness, or luminance, of the part of the image being drawn onto a screen at the same point in time.

A variety of styles are available for the Waveform, including Luma + Chroma, RGB Overlay or Split, as well as YRGB and YCbCr split.

Vectorscope

 

The vectorscope is used to visualize chrominance, which is encoded into the video signal as a subcarrier of specific frequency: it plots the Cb and Cr channels against each other, for the purpose of measuring and testing television signals.

 

Histogram

 

A histogram is a graphical representation of the tonal distribution in a digital image.
It plots the number of pixels for each tonal value. By looking at the histogram for a specific image one is able to judge the entire tonal distribution at a glance.

Luminance Meter

 

The Luminance meter is used to measure the photometric brightness of an HDR image. It measures the amount of light that strikes a surface in the picture.

Zebra mode

 

Immediately visualize the out-of-bounds values for a maximum and a minimum luminance setting.

Peak Signal-to-Noise Ratio

 

The PSNR computes the peak signal-to-noise ratio, in decibels, between two images. 

The result of the PSNR analysis is avaible viewable in a scope and can be exported in PDF and XML.

Bitrate Meter

 

The Bitrate meter measures during the playback the encoding bitrate of the content.

Audio analysis

Loudness Meter

 

The Loudness meter measures the human perceived loudness of an audio content.

The Loudness Meter is based on the EBU R128 Loudness recommendation.

Peak Meters

 

You can display Peak Meters information, Sample Peak and True Peak.

  • True Peak shows the peak level of the waveform no matter how brief its duration.
  • Sample Peak shows only peak sample values, not the true waveform peaks.

 

Surround Meter

 

In this meter, the positions of the full range loudspeakers are marked on a graticule and the amplitude distribution of the sound-field is used to modulate a visual representation, also called “jellyfish display”.

Phase Meter

 

The phase relationships that exist between channels of a multi-channel audio system represent critical information to a quality-control engineer.

Room Meter

 

This meter allows a real-time 3D visualization of the immersive audio objects positions in the room.

Advanced quality control

File-based QC support

Reports from automated file-based QC solutions can be loaded on the timeline, allowing the operator to manually inspect the errors of a media by navigating on the timeline from error to error.

Supported solutions: Aurora, Baton, Pulsar, Vidchecker

Standards Validation

Compliancy tests and validations are available for a large variety of masters, including DCP and IMF packages.

Results are available in the form of PDF or XML reports.

Subtitles Inspection

A perfect rendering of all type of subtitles, including IMSC1, XML SMPTE, EBU STL:

 

  • Control of the subtitles using the spotting list
  • Text luminance management
