Leader LV5381 Chosen For Digital Workshops

Leader has announced news that film producer and cinematographer Matt Siegel chose its LV5381 four-input multi-SDI monitor for use during his recent seminar on Digital Cinematography at The Maine Media Workshops. The course focused on the advantages of using digital technology and explored the challenges and limitations of various digital formats.
"The seminar addressed the special requirements of lighting for digital cinema, using light meters to achieve correct exposure, working with the camera's dynamic range, balancing and correcting mixed lighting sources, and calibrating video monitors to accurately display images," Matt Siegel explains.
"It also provided an introduction to the digital workflow, the post-production process and the output options for the finished video.
"The LV5381 was fantastic, both as a production instrument and as a teaching tool. It provided a precise and efficient way of explaining the structure of video and audio signals, and showed graphically how to get the best possible image. Being able to view multiple displays such as a video waveform and chroma vectors alongside the actual video image was especially powerful."
Matt Siegel's background centers on commercials, branding and communications. His company, Imageworks, produces spots for brands such as Audi, Coca Cola, Ford, Google, MasterCard, Microsoft, Sony and Toyota. He conducts camera and lighting workshops around the world, demonstrating production techniques and new technology for ARRI, Canon, Panasonic and Sony.
Leader's LV5381 is a complete multi-screen HD/SD-SDI video and audio test system measuring 4U by half rack width.
HD-SDI or SD-SDI signals from up to four cameras can be monitored on the instrument's integral 8.4 inch TFT-LCD screen.
Picture monitoring features include colour temperature specification; brightness, contrast, and aperture adjustment; and the display of gamut error locations. The four channels can be viewed individually at full-screen size or simultaneously. Each input channel can be assigned its own color to simplify comparison of video signal waveform and vector displays.
Selectable display parameters include video signal waveform, chroma vector, five-bar video peak level or picture monitor. A level meter display shows embedded audio. Transmission error can also be displayed. Incoming Y/CB/CR signals can be viewed as as RGB or pseudo-composite waveform with line selection and adjustable waveform magnification.
The LV5381 accepts tri-level sync signal or can synchronise to NTSC or PAL black burst. Up to 30 front panel presets may be stored internally. Captured data can be viewed onscreen and saved as bitmap files to USB memory for export to a PC.
Each LV5381 comes complete with CINELITE and CINEZONE video signal luminance information analysis tools.
CINELITE allows any three points on the picture to be selected. It then displays their f-stop numbers, percentage values, and level values. The size of the measured point can be adjusted from a single pixel to the average value for 9 or 81 pixels.
