What Are Fade Effects?
Attractive Effects for a Demanding AV project
AV system integrators must develop and deploy projects that 100% match the customer’s requirements. Even the quality of the solution must supersede the expectations in order to achieve perfect customer satisfaction.
The quality of video presentations is a key factor in demanding AV projects for board rooms, show rooms, university halls, conference centers and in any place where different video information must be presented to small or large audience. DEXON devices can in face provide these excellent visually appealing presentation effects to equip such AV installations.
The visually outstanding offer gives video presentation effects like seamless switch or fade switch between input video sources to be displayed after each other or in a sequence. The smooth change of a certain video content to another source can be achieved by fading effects as by far the best services for a single screen or even for a video wall of several monitors.
What are fade effects and what to use them for?
Fading means a smooth change of content from a certain video input while displaying a second video content of another video input over the very same screen. Usually such a change results in interrupt in the visualization because the first video signal is stopped and the second video signal is started.
The monitor gets out of synchron and must synchronize to the second video signal’s resolution with black screen content. This may take seconds and usually the control device displays black frames and even customers may see signal distortion. This is rather disturbing especially for frequent video input change and even for large video walls.
Fading needs smooth but real time change of the video content resulting in a nice transition effect. This smooth transition is well accepted by human eyes and so the audience will be able to watch and to enjoy frequent changes over the monitors or over a video wall of several screens.
The fading may have different forms such as fade out of the video content to the background, fade in the video from the background but the top solution is cross fade between two different video input source contents in real time.
Fade in effects
Fade in effect can be used to display new video information from a static background. In case of matrix switching, this means visualization of a new video signal to a certain output. On the output the visitor may see the static and still background first and the video signal comes up smoothly. This operation must be performed in real time and usually the transition time may be programmed.
In case of a video processor, the fade in means display of the new video window over the background and the new video content smoothly evolves from the background. This operation must be performed parallel over the coherent video wall of several monitor screens and of course in real time.
Fade out effects
Fading out effect can be used to dissolve video information to the static background. In case of matrix switching, one can witness a smooth switch off of a video signal from a certain output.
On the output the visitor may see the video dissolving while the background information appears smoothly. This operation must be performed in real time and usually the transition time may be programmed.
In case of a video processor, the fade out effect refers to the transition form, where the video content of a certain video window smoothly dissolves to the background. This operation must be performed parallel over several monitor screens in real time.
Cross fade effects
Cross fade effect can be used to swap two live video contents in a smooth way. In case of a matrix switcher, the first video content displayed on a certain output does not dissolve to the background but it will be swapped smoothly with the second live video content in a rather elegant way.
Each of the videos must be live during the cross-fade operation without any interrupt or signal glitch. This operation is performed in real time and the transition time may be programmed also.
In case of a video processor, the cross fade means that the video content of a certain video window smoothly changes to the second video window. The background does not appear at any time during this switch. This operation must be performed parallel over several monitor screens and always in real time.
Are these fade services available?
All of the afore mentioned visual effects are available in DEXON Systems’ DIMAX presentation matrix switcher products where customers can define different effects for any or all of the output monitors. The DIVIP video processor products support fading also where customers may enjoy different effects on certain output monitors or even the very same fade over the video wall.
AV system integrators can benefit from using the high-tech fade effects, because these video effects provide a flawless display by providing smooth and advanced transition between input videos or images. The audience has an attractive and relaxing experience when using fade effect to display multiple videos.
These presentation services give total customer satisfaction in your demanding AV projects for board rooms, show rooms, university halls, conference centers and in any place where video or graphics information must be presented to the small or large audience.
