    RF1225FP. Retro Reflective Backdrops are used in conjunction with LED Light Rings that mount onto the lens of the camera, such as the Datavideo CKL-200. The unique properties of the backdrop will allow you to get away with having the odd crease line, and the whole system is quick to set up. If you are looking for a portable system you will be hard pushed to beat the LED Light Ring / Retro Reflective Cloth combination.

  • Page 6: Lighting

    Lighting Lighting of your chosen backdrop is extremely important; the more even the lighting on the backdrop the better the finished result. Lighting setups for the foreground subject will vary according to the effect you want. For chroma keying backdrops even lighting with no hotspots or shadow areas is the aim. This is easiest to achieve with a set up something like this: In the diagram you will see we recommend a minimum of 1m between subject and backdrop, it is always easier to get even lighting if this distance is greater, so please think of 1m as the absolute minimum.

  • Page 7: Functions

    Functions The DVK-200 has two inputs (one camera input and one background input). Each of the inputs can be set to CV (Composite Video), S (S-Video (Y/C), YUV (Component) or DVI-I. All of the outputs, one Y/C (S-Video) and two Composite, are simultaneously live. We recommend that YUV or Y/C is used for the camera or source inputs wherever possible.

  • Page 14: Monitors

    Monitors It is possible to use the DVK-200 with just one monitor, connected to one of the output sockets, but many users prefer to monitor the Camera (Foreground) and the Background Video in addition to the main keyed output. Monitors can be connected using either S-Video or Composite Video cables. Many monitors do not feature an S-Video input, and therefore must be connected using Composite Video cables.

  • Page 15: Using The Dvk-200

    Make sure the power cord is plugged into an appropriate mains socket, and that the socket is switched on. Switch the DVK-200 on, using the On / Off switch on the rear of the unit. All the buttons on the front panel should light up for a couple of seconds, and then the DVK-200 is ready.

  • Page 17 We can see in these images that a strong dark edge is running along the left edge of the subject. To correct this we will use the Left Shrink Adjustment. If there is an edge on the right we would use the Right Shrink Adjustment, the procedure is the same for either side.

  • Page 18: Subject Density

    The DVK-200 has another fine tune adjustment called Subject (or Foreground) Density. This adjustment will make your subject more or less opaque / transparent; as a result the edges will become more or less defined.
  • Page 19 Press the Right Arrow button so that it is illuminated red. Turn the Adjustment Knob to the left; On the output monitor you will see the background gradually coming in from the right to cover the un-keyable area of the camera image.

    To unlock press and hold the GREEN Key-1 or BLUE Key-2 button, again for two seconds, until the button returns to being illuminated red. All of the settings are non-volatile, so they are held in memory even after the DVK-200 is switched off. When the DVK-200 is switched on all the parameters will be as you left them.

  • Page 21: Luma Keying

    Luma Keying As well as being a Chroma Keyer the DVK-200 can also be used as a Luma Keyer. A Luma Keyer can key out luminance values. In simple terms this means you can key either with the Black end of the grey scale, or the White end of the grey scale.
