Field Report: Leader LV5333 Gives I Love Hue an Edge

The Leader LV5333 reveals precisely where lighting hotspots are to help deliver the best chromakeys possible.

Alix Milan, founder and Managing Director of I Love Hue Ltd, is the latest in a growing number of broadcast production creatives investing in a Leader Instruments LV5333 3G/HD/SD-SDI waveform monitor.

I Love Hue Ltd is a London-based DIT agency aiming to provide high quality color and workflow support in the UK features and commercials market. Founder Alix Milan started his career at a large London post-production house before expanding into a more hands-on role for most of his clients. The LV5333 has become integral across a wide range of his activities including feature production, music videos and commercials.

"Many of my clients insist on having Leader test equipment on set." Alix Milan comments. "I have been using LV5330 instruments for a long time and chose the LV3333 to handle the increasing demand for high dynamic range. 3G compatibility was also an important requirement.

"The ability to isolate and inspect specific areas of the image is especially useful when we are lighting for green-screen or blue-screen chromakey. With the LV5333, we can see very precisely where the lighting hotspots are and how they affect the overall superimposition. It saves a lot of time and delivers the best keys we could possibly have.”


"Leader's CINEZONE false-color function is also extremely useful for showing how a scene is lit in general. It is very easy to read when we are lighting skin tones and backgrounds, showing whether the fill and key-lights are providing enough punch or too much.”

"For scenes where there is not a lot of light, the LV5333 enables us quickly to set a minimum value below which anything becomes black, so we can see exactly where in the image we need to put extra light. All my colleagues who have used it have also been very impressed. CINEZONE makes lighting analysis so much easier that I don't know how we ever managed without it."

"HDR will quite obviously play a major role in the evolution of broadcast television standards, whether for HD, UHD or Hi-Vision," adds Leader's European Regional Development Manager, Kevin Salvidge. "It enables program producers to deliver images with extremely high impact across the full range of contrast depth from highlights to deep-shade detail. The LV5333 allows producers to capture the full available dynamic range right during the original shoot rather than having to boost the bright and dark regions during post production."

The Leader LV5333 is compatible with over 20 HD-SDI/SD-SDI formats, and designed for deployment in studios or technical areas, or attached to a camera tripod and battery powered. The integrated 6.5 inch XGA TFT LCD screen can also be used to display video signal waveform, vectorscope or the video image. CINELITE, CINEZONE, histogram, gamma display, gamut and level error display functions are included as standard.

Additional features of the LV5333 include cable length display, external timing display and field frequency deviation display. SDI-embedded audio can be extracted, and two user-selectable audio channels sent as an AES/EBU stream to a BNC output. The levels of up to eight audio channels can be checked using on-screen bar displays. User-configurable multi-display combinations within the LV5333 allow easy inspection of signal parameters. Full-screen displays can alternatively be selected to allow detailed review of specific elements.

The recently introduced LV5333SER02 HDR option enables the LV5333 to measure HD HDR and 2SI 4K in ITU.BT.2100 Hybrid Log Gamma, Dolby PQ or Sony Slog-3 protocols. The CINEZONE option for the LV5333 supports false color display in each of these HDR protocols. In addition, the waveform display now supports PQ scales of 4000, 1000, 400 and 100 cd/m², as well as 800% and 500% for HLG.
