NEW TECHNOLOGY FOR COLOR GRADING : THE NEXYAD SKINS

(French Version)
NEW TECHNOLOGY FOR COLOR GRADING : THE NEXYAD SKINS

by NEXYAD



INTRODUCTION
The digital post production has merely reproduced the old post production phases, using software whose
interfaces were comparable to those of physical machines previously used.
Eg interfaces using the « slider », the « button », etc … all of which were essential to set an analog electronic
machine or a mechanical machine or mechatronics.
But digital also allows to completely change the way of thinking and will soon revolutionize workflows in
post-production film and television.
Indeed, suppose that there are two control buttons on a machine (eg overall luminance and overall contrast),
we can draw this:
Luminance & Contrast
The rectangle materializes all possible settings of the image using these two buttons which can rotate independently of one another.

« Turning the knobs » to go from one setting # 1 to # 2 setting means « moving » in the diagram:
Contrast Button

With digital technology, one can easily reproduce this mode, but you may also « pave » the rectangle with
predefined positions that have been judged as « interesting » by experts and then « jump » from one position to another:
Contrast settings

One can imagine letting the user move in « button mode  » around predefined positions … Then all areas of the rectangle can be achieved, but preference is given to Presets which has already been validated as aesthetic.

This means that instead of « moving » continuously from one setting to another, we now « jump » from one setting already validated to another validated setting.
Advantage: jumping does not go through the settings which lead to unpleasant images, one goes straight on already validated settings.

CRITICISM OF THE METHOD
It can be argued that this approach is to spend « tailored » to the « ready to wear ».

Yes, but for those who do not have the budget to pay for custom-made, the solution is very inefficient: you’ll see a poor tailor who certainly takes your measurements, but then is not very well paid for quickly making a bad cut in poor tissues, and your suit at the end is not very beautiful.
You have the illusion of tailor-made, but you do not have the budget to turn the knobs very far.

In a « ready-made » solution, if the number of different costumes for sale is very large, in one hour you try dozens. It is much more efficient and cuts can be very sophisticated because stylist work cost was made one time for tens of thousands of customers.
Our response therefore is to know where you are in the chain of budgets : low ? average ? high ?
Furthermore, nothing prevents you from taking the ready to wear and do everything custom touch then.
Our solution is optimal in terms of price / quality ratio.

Moreover, the argument of « creativity » clamped is also very questionable: when one has no budget to work for a long time involving global experts of the field, then, turning knobs, and even if the result is aesthetically acceptable, it is likely to be find a result that is already known and already used repeatedly by other filmmakers.
This is not because we do not know anything that we are original. The application of N color grading (example: twenty) on your film, even if it is only to « see », will help you do your own way and making sure you are original.

EXAMPLES OF NEXYAD SKINS
The images below are presented for illustration. With NEXYAD SKINS, you don’t need to know how the images were initially, simply look at the end result, choose one that you like, and you can get it on your own images.
This is a revolution in post-production. Here are the first skins that NEXYAD has developed :

NEXYAD developed a new release of their digital video sequences advanced denoising system (March 4, 2011)

NEXYAD developed a new release of their digital video sequences advanced denoising system : this new version of the NEXYAD algorithm can denoise video sequences (digital image sequence) without bluring any contour. Applications are milirary and defense (noisy video sequenses understanding), movie digital image post production calibration and special effects (that can’t be efficient on noisy images), pattern recognition pre processing.
