So, how do you plan on playing back this finished color correction? Do you have a theater quality projector? If not, your aim is without merit. You will have to convert and then convert it back to RGB to do anything with it so what is the point in converting it in the first place? If you start with an RGB source (GOUT, DVD, and BR) and you are going to watch it on an RGB device (Any color television ever made) with an RGB file type (as DVD and BR require), I really don’t see the point of your exercise. You are trying to recreate the wheel and there is no reason to. Calibrate your monitor first. Then stick to RGB (what your source and end viewing will be in). That is the colors our eyes see after all. Unless you have calibrated professional equipment designed for theatrical projection, there is no reason to change the color space. If it starts out RGB and ends up RGB and gets to your eyes in RGB, then … it is an exercise in uselessness. Especially without a calibrated monitor. Yours is obviously way off.

I can not seem to get it through to you but I will try again.

Anything RGB will display the YUV or Ypryb colorspace correctly.

The filter to do the hue shift though can not be done from the roots of Red Green and Blue because the math is off that is why it creates the weird / odd error. Womble did have right sort of hue shift but the filter itself was poor.

What ever filter is in VLC is the right filter to use for hue shifting the Gout which Lightworks does not have only strict RGB root shifting.

Any hue shift does not require calibration because it is relevant only to how the footage or file is. There is no added or color taken away only shifted and the aim is to shift it so that it is not off base i.e. shifted away from where it would be normally. Correcting for the shift that it is plagued by.

you can watch it on any RGB device no problem.

I can’t say it any more times I am talking about a video filter and how it handles and trying to find away atound the problem, even you said yourself you can’t use it… I say you can if you use the right one.

Anymore of this sillyness, If you still can not understand that the filter acts differently in VLC than root shifting from RGB then I just at a loss of explaining this to you. This conversation also has nothing to do with film prints. It is a practical based thread on why color hue shifting is not a bad thing if done a differenh way.
