New Leader in 4K waveform monitors

The new LV5490 SD to 4K multi-standard multi-waveform monitor from Leader Instruments supports all standard video production and transmission resolutions from 525 and 625 SD up to 3840x2160 and 4096x2160 4K.

The new LV5490 SD to 4K multi-standard multi-waveform monitor from Leader Instruments supports all standard video production and transmission resolutions from 525 and 625 SD up to 3840x2160 and 4096x2160 4K.

“High quality 4K cameras are becoming so affordable that the format is being adopted by many digital cinematographers and video production companies,” said George Gonos, president of Leader Instruments Corporation. The monitor, expected to start shipping later in the year, includes “many of the features that have made our SD and HD instruments easy for use by creatives working intuitively. The LV5490 is also a great tool for engineers.”

It has four 3G-SDI/HD-SDI/SD-SDI input channels plus a high-quality, wide-viewing-angle 1920x1080 9-inch flat-panel display that allows precise matching of studio or outside-broadcast cameras. The instrument also doubles as a picture monitor and has several features specifically for use with 4K cameras, such as Sony’s F65.

Each input includes Leader's cable length measurement capability, and both 3G-SDI dual link and quad link are both supported. There are also SDI and DVI raster outputs, Ethernet, RS-422 serial control, eight digital audio inputs/outputs, eight SDI inputs/outputs, external reference and 75 ohm loop-through, 90 to 250V 50/60Hz mains power input and ground.

4K images can be divided into upper left, upper right, lower left and lower right areas and output as four-wire or two-wire 3G-SDI channels. The LV5490 can also downconvert 4K into an interleave-sampled 1920x1080 pixel monitor feed.

Test and measurement features include: waveform, vector and picture monitoring; SDI signal data analysis; cyclic-redundancy-check error; embedded-audio error; event log; data dump; and timing display. Leader's Cinelite II toolset also comes as standard to assess relative exposure and overall luminance.

Waveform, vector and picture display can be viewed simultaneously on the LV5490 screen. Simultaneous display and overlay display of multiple SDI inputs is possible. Size and location of individual channel displays can be adjusted using a USB-connected pointing device.

Additional features include: video frame capture; instrumentation screen capture; timecode display; tally light; and ID display. Eye pattern display, jitter waveform display and Dolby decoding are optional extras. A rack mounting adapter will also be available.

Leader's S-LOG2 option will allow digital cinematographers to make the fullest use of the Sony F65 camera's 4K imager, extended chroma gamut and 16-bit linear dynamic range. It gives immediate visual information such a precise zoom-in monitoring of focus across user-selected areas of a video source. Exposure detail can be checked accurately at the press of a button. A high-key filter can be activated to evaluate highlight detail and then a low-key filter to inspect shadow detail quickly and repeatably. Users can also apply a user-adjustable exposure/luminance-referenced chroma scale over the image, allowing them to match the White Clip indication on a Sony F65, False Colour on an Arri Alexa or Video Check on a Red Epic.

Optional digital audio monitoring and analysis tools include 4x4 channels of SDI audio de-embedding, Lissajous display, surround sound display and volumetric display. Up to 16 channels of de-embedded SDI audio can be output as discrete AES3 feeds.

The LV5490 will be launched at IBC (stand 11.A38), and is a 4U (half rack) size housing, with a carrying handle, weighing about 4.7kg.
