AJA HDR Image Analyser

Description

Analyse 4K/UltraHD HDR video in real time with the AJA HDR Image Analyser developed with Colorfront HDR monitoring and analysis software. The 1 RU device provides four 3G-SDI inputs and four 3G-SDI outputs that support up to 4096 x 2160 4K and 3840 x 2160 UltraHD resolutions with high dynamic range, wide colour gamut, and LOG colour formats.

The Image Analyser supports dynamic range inputs such as Rec.709, ST 2084, and HLG, and BT.2020 and BT.709 colour gamuts common in live production, DIT workflow, broadcast monitoring, post production, and final mastering. The software UI is accessed via DisplayPort and USB ports and gives you access to tools such as waveform, histogram, vectorscope, colour gamut, error logging with timecode, brightness levels, data analysis, and advanced error detection.

The Analyser also supports up to 16 channels of audio for monitoring with level display. There's an audio phase metre that can be configured for stereo or surround display, and it can provide level warnings in your logs.

In addition to the eight 3G-SDI in/out ports, the unit also features a REF input and four DisplayPort connections for monitoring at up to 3840 x 2160 at 60p. Three USB 3.0 and two USB 2.0 ports provide keyboard and mouse control, as well as to plug in external drives for offloading log data or upgrading firmware. The unit also features two redundant 110 VAC power supplies and comes with two power cables.

Monitor, Analyser, Log the Results

Features a high-quality UltraHD user interface for native resolution picture display, critical for close analysis of your video materials, making the most of the tools you need:* Waveform

• Histogram
• Vectorscope
• Colour Gamut
• cd/m2brightness level
• File-based error logging with timecode
• Data analyser with advanced pixel picker
• Advanced, out of gamut and out of brightness detection with error tolerance

Camera LOG Inputs

Provides direct input for a range of camera LOG inputs, allowing direct connections from various camera brands and immediate analysis of production feeds.

Video Resolution

Address your video resolution setup needs with quick access from the Video Resolution menu, with easy access for RGB, YCbCR, and Quad split vs. 2SI configurations.

Choose Setups and Capture Scenes

Setups can be saved and recalled for quick configuration when moving between projects and tool configurations. Scenes can be captured for quick recall and saving to be shared with others for a great visual representation of any issues that need to be addressed.

Colour Space

Several different colour spaces can be utilised for analysis including 709, P3, XYZ, and 2020, as well as camera native colour spaces. HDR Image Analyser also offers an Auto HDR mode change for automatic HDR colour space triggering when possible.

Waveform Lumi Colour

Offers a range of views for waveform representations including Waveform Lumi Colour. Waveform Lumi Colour offers a gorgeous combination of both luminance and colours in the project's colour space.

Vectorscope

Vectorscope displays the colour saturation of each pixel in the video frame, with the middle of the circle indicating a lower saturation level, and the edge of the circle indicating a higher saturation level. The vectorscope additionally offers a zoom feature and a skin tone line, whose value can be manually set as desired, especially useful for ensuring consistent skin tone results for sequence work and camera matching.

Whitepoint

HDR Image Analyser allows you to set a white point relevant for the project at hand. Choose between DCI, D65, or simply turn it off.

CIE XY Gamut View

In HDR mode the CIE XY Gamut View can be used to cheque the encoded colours, and whether they are within the valid limit of colour range. This is relevant when working in the Rec.2020 colour space where the actual pixels are supposed to be limited to the P3 colour gamut.

False Colour - Gamut Warning

Out of Gamut False Colour mode provides a clear visual representation of areas of your image that may present a problem. The results can be saved automatically within your logged files for QC needs.

Pixel Picker

Glide your mouse across your footage and use the Pixel Picker to give you a read out of the exact pixels cd/m2level, Hex, or Decimal code values.

Logs

Detect P3 gamut violations and brightness violations in HDR events and logs them with time stamps in a log file and on screen. Log files can then be collected for sharing with your team as necessary.

Timecode

Timecode may be overlayed on screen to assist with quickly identifying any areas of concern at particular moments in a sequence or shot.

Audio Metering

An audio level metre is included for up to 16 channels of metered monitoring and display of peak dB levels. An audio phase metre can also be configured to display either 2-channel (stereo) or 8-channel (surround) audio. Audio level warnings may be set to generate notes into your logs.

Analyser Gain

Analyser Gain allows you to increase or decrease the gain put out to your display, simplifying your ability to monitor critical items with dark footage in particular.
