Indigo AV Mixer Effective Use of the Hi-Res Option
Contents
1. There are a few additional points reflected in this diagram e Hi Res Input 3 is always an upscaled SD source It is not possible to assign an external source to this input e While the Hi Res option supports chroma and luma keys these are video or self keys It is not possible to assign a separate key and fill in high resolution mode e You cannot assign the same source twice in high resolution mode For example the same source cannot be assigned to both keys or to the background and a key This is different from the SD keys which can be assigned to the same source e In high resolution mode there is no option for de embedding HD SDI audio Hi Res Video Processor e Using the setup menu you can assign the downscaled PGM and PVW outputs of the Hi Res option as SD sources By default PGM is Input 9 and PVW is Input 10 These sources can be used as SD backgrounds keys or auxiliary outputs like any other SD source e Because you are routing the entire high resolution program to SD it is important not to have the SD program routed to scale back up to high resolution If you include the scaled sources in the SD program under these conditions you will create a video feedback loop This is not harmful to the mixer but it does create significant picture distortion in the looped sources 8 bit High Resolution to 1400 x 1050 or HD to 1920 x 1080i Inputs 1 2 From SD side Input Selector Inputs 1 2 DVI D DVI2. manual 2x Downscalar Selectable to scalar Digital Video 10 bit RGB Standard definition 2 keys 2 channel 3D Digital Audio 24 bit 48 kHz 4 band EQ per channel Auto timing Figure 1 ndigo architecture with Hi Res option www grassvalley com Embedded PGM PVW AUX PGM PVW Main Sub To match the many formats used for live events the Indigo mixer offers an option for upscaling rather than simply high definition Called Hi Res this option enables it to scale inputs to a full range of outputs Including e 800x600 50 59 94 e 1024x768 50 60 75 e 1280x720 50 60 75 e 1280x768 50 60 75 e 1366x768 50 60 75 e 1280x1024 50 60 e 1400x1050 50 60 e 1920x1080 50 60 INDIGO AV MIXER EFFECTIVE USE OF THE HIGH RES OPTION High Resolution vs High Definition For the best picture quality the output resolution of the mixer should match the optimal resolution of your projector or monitor The mixer will scale all inputs to match the desired output resolution You can select the output resolution in the Setup menu on the Indigo touchscreen under SETUP gt VIDEO gt OUTPUT Installing the High Resolution Card When ordered with the Indigo mixer the optional Hi Res input card will arrive uninstalled To safely install it remove it and the base unit from the box and place on an anti static work surface With all power disconnected remove the cover plate from the back of the mixer The l

Audio Setup There is not a separate audio menu In the Indigo mixer s high resolution mode Audio signals coming into the mixer via HD SDI are lost Audio follow video for high resolution sources is assignable in the audio menus High Resolution Keys You can set up high resolution keys Figure 5 using the same menus as the SD keys The menu options change according to the selection The high resolution key parameters for border and patterns are not available As mentioned earlier the current version of the Indigo mixer does not support the assignment of the same high resolution source twice SD Key 1 SO Key2 HO Key HD Key Type Source Adjust ane 0 50 0 38 Pan i Zoom 20 Position 100 1 00 1 00 5p size High Resolution Effects The the Indigo mixer s Hi Res option contains a basic library of wipes that you can assign to the background or to either of its keys This library includes e Left e Top e Cross e Rectangle The Hi Res option does not have digital effects Other Options Still stores are available for high resolu tion graphics Color correction has fewer gradation steps Basic Workflow Using the Indigo mixer to run an event with both SD and high resolution sources is similar to using a 1 5 M E broadcast mixer You have to switch between M Es SD and high resolution to change the sources routed to that particular M E Since these M Es use the same hard ware
