Lower CRI values indicate that some colours may appear unnatural when illuminated by the lamp. A CRI of 100 represents the maximum value. One way of offering clarification of the comment is to provide some information, kindly provided by the ‘ Rensselaer Polytechnic Institute’, which states that “ CRI is calculated from the differences in the chromaticity of eight CIE standard colour samples (CIE 1995) when illuminated by a light source and by a reference illuminant of the same correlated colour temperature (CCT) the smaller the average difference in chromaticity, the higher the CRI.
SMART WALL RENDER HOW TO
Having now provided the definition of Colour Rendering Index, the next consideration is that of how to measure CRI and the first point to get across is that it is a complicated process. One important consideration to offer, is that Colour Rendering Index has nothing to do with ‘colour’ in that it does not indicate the apparent colour of the light source.
This simplified meaning of the definition given above is that the Colour Rendering Index is a quantitative measure of the ability of an electric light source to accurately reproduce the colours of an object being illuminated by that light source. Having mentioned the words of colour rendering in the opening paragraph above, I suggest that before continuing any further, it is now time to offer some information extracted from the Commission Internationale de L’Eclairage (CIE), where Colour Rendering Index is defined as being the “effect of an illuminant on the colour appearance of objects by conscious or subconscious comparison with their colour appearance under a reference illuminant.” This editorial considers the metric of firstly, that of Colour Rendering Index, in the second part, being that of Colour Quality Scale, and in the third part, being that of a metric commonly referred to as TM30.
SMART WALL RENDER SERIES
OCTO delivers the complete smart lighting package to transform the efficiency and ambience of commercial and residential spaces.Ĭolour rendering – Colour Rendering Index (CRI)Ī technical look at Colour Rendering Index (CRI)Ĭolour conveys the information received through the eye, which provides a picture of what is seen by the observer in the world around them, and as part of that process, the colour rendering properties of electric light sources are important in conveying the true colour, or as near as possible, the true colour of the objects being viewed.īefore getting into the main topic of this editorial, it is relevant to say that the information contained is offered as part of a series of three editorials based upon the available metrics of measurement in how an electric light source renders the colours of an object being illuminated by it. Whatever the shape, purpose or style of your space, we have a lighting solution. If there are changes (for instance, when titles, video filters or transition effects have been added), it renders out only the edited portions, making render times much shorter and faster.We are a leading manufacturer of quality internal and external lighting products for commercial, industrial and retail applications.Īt Ansell Lighting we design and manufacture an extensive range of luminaires for a diverse number of applications. The SmartRender feature detects any changes in your project and if there are no changes, instantly plays back the preview file. When you preview your video project for the first time, VideoStudio ‘renders’ the project by creating a temporary preview file on your hard drive which combines the video, image, and audio clips with the special effects which you applied to them. This can reduce rendering time significantly.Ĭorel VideoStudio’s SmartRender feature makes previewing and creating movies a lot faster. Smart Render analyzes a video for any previously rendered sections and renders only the new or revised sections. VideoStudio has implemented a smart render system to speed that process up and only render the parts of the film that need rendering.
Rendering can take an enormous amount of time in video editing, especially when the video is long and includes a large number of effects.
Follow along with our tutorial below to learn the easiest way to enable smart render.
