The LV5381 is a waveform monitor that can monitor up to four SDI signals simultaneously. It is optimized for the level adjustment of the outputs of multiple installed cameras. In the video signal waveform display, vector display, and picture display, multiple input signals can be displayed on top of each other or lined up next to each other.

It is also full of useful features such as a level meter display for embedded audio, an error display that indicates transmission errors, and a 5-bar display that shows video signal peak levels using five bars. Furthermore, the LV5381 can show different combinations of these displays in its multi-screen display.
  Why Do You Need The LV5381 Instead Of A Monitor With A Waveform Display? LV5381 has features you won't find on a video monitor, such as:

• CINELITE® - Use a cursor on the picture to check luminance values.
• CINEZONE® - The best false color luminance display in the industry.
• Full screen accurate Waveforms in RGB and YCbCr, Vectorscope, and Audio Displays.
• SDI Error Monitoring on the Status Display, to see if there are any issues with the video signal. Plus an External Phase Display for Timing (Option LV5381SER03)
• Monitoring of up to 8 channels of embedded audio, with a full screen or quarter screen, easy to read Audio Display with dB level indication.
• Lissajous Display - To check audio phase (Option LV5381SER02)
• 5-Bar Gamut Display to make sure a signal is legal.
• Screen Capture function to capture the displayed image and save it to the internal memory or to a USB memory device. Great for documenting technical problems, matching cameras and scene continuity.
• Custom False Colors, false colors used by two camera manufacturers and the SLOG2 Gamma curve (Option LV5381-OPSLOG2)
• Flexible Configurable Displays

CINELITE® On-Picture Exposure Measurements

Designed with feedback from both film and video professionals, this new on-screen measurement option offers additional measurement functionality on award winning Leader HD and SD monitors. Essentially providing the function of a spot light meter, CINELITE® provides on-picture measurements of video levels in % RGB, Y percentage and f-stop readings, bridging the gap between film and HD production measurements.

For the first time in our industry, you can now review and evaluate your set, after the camera has processed the image. Point a cursor to any position on the picture to get instant measurements in f-stops (or percentage) and review the material that is actually being recorded. Final adjustments of lighting conditions, filtering and iris adjustments can be made using familiar gf-stop h based evaluation techniques. The resulting measurement is digitally accurate and represents the material as it is actually recorded. This ensures scientifically accurate communication with the post-production and color correction process while enhancing the understanding of film and video experts alike.

CINELITE® f-stop measurements allow DPs and cinematographers to evaluate their HD or SD production using the same measurement techniques that have produced excellence with film over decades. Essentially, the CINELITE® option allows HD production professionals to evaluate their lighting and exposure in real time and helps create a set-evaluation and exposure determination workflow environment similar to working with film.
   

CINEZONE® Exposure Zone False Colors Display

Instant view of your lighting conditions and easy determination of exposure zones. CINEZONE overlays false colors on the image—the colors are determined based on the scale on the left; blue indicates near-zero values, red indicates values at 100%. This helps confirm your camera is reproducing what you expect. As a side benefit, shadows are highlighted in blue, making it a lot easier to examine shadow detail using the CINEZONE display. Adjustable upper and lower limits add black and white color overlay to indicate under exposed and over exposed conditions without having to reference the waveform monitor.
