    Earaser on Secondary Correction?

    Hey guys,

    I am kinda new with Avid Symphony and I am trying to improve my final result a little bit.

    For example,when I take a shot,this shot got a person with a green shirt. I click on the "Set input vector color" and choose the range of those shirt's greens. then it automatically Isolate my shot and I am able to change the shirt to another color. the problem is,that it selects other "points" of green in other areas of the shot although my background is sort of orange. Is there any chance to improve the selection to restricted areas of the picture? so I won't get all greens of the picture in my input?

    or have kind of eareaer like in photoshop to earase all those "points" from the shot?

     

    and yes,I absolutely read this paragraph:

    It is important to remember that a secondary color correction affects all of the pixels in an image that fall within the selected input color range, so your ability to make a successful secondary correction depends on the overall color values of your image.

     

    I know I am able to play with the hue width \ sat min \ sortness

    to make it more restricked but still it's not easy to get the exact result I want.

     

    Thanks in advance,

    Elaad

    It sounds like you're looking for a Vignette. Unfortunately this isn't available in the Color Correction toolset. My only suggestion is to take a look at the Spot Effect. You might be able to get to the same place with the Paint effect using layers.

    Re: Earaser on Secondary Correction?

    People says that one picture can tell you 1000 words. In that moment I think that one word in your whole paragraph did exacly the opposite.


    I googled for the Vignette

    And I got

    which opened me to new different ideas that might solve my problem.


    Thanks a lot!

    You could apply your color correction on filler over your clip

    (use the color correction effect in the effects palette)

    Remember to enter color correction mode with the red (overwrite) segment selection tool activated

    Then apply an animatte (alt+drop) on the color correction effect and key out what you don't want corrected.

    How do I key out what I don't want to be corrected?

    There is no simple way to do this. 

    You have to double up you clip by placing it on layer above. --> then apply your secondary color correction to the lower clip --> then use the antimatte tool and tracking commands to isolate the "green shirt"--> set the mode to 'Key Out' --> render.

    It's quite a process - one that you get quick at after using Symphony for ten years - and yes it is annoying that you can't do all this within the CC tool. Nevertheless most of us have been hoping this will change with the next major release of the software - mind you I've had my fingers crossed for 10 years now!

    Re: Earaser on Secondary Correction?

    I assure you the trick I mentionned above works very well, you do not have to double up your clip.

    Try it, I always do it that way when I have unwanted parts of the image that change color on a Sec CC.

    Fast and easy

    Re: Earaser on Secondary Correction?

    The problem with using animatte and spot effect to vignette is that they are both 8 bit effects. When you use them with secondaries your footage will take a quality hit. You can see banding, especially when you feather.

    I do not understand why you can't do this inside the CC tool. I would like to see a the CC tool use a higher bit depth too. I believe it currently uses 12 bit.

    Re: Earaser on Secondary Correction?

    I use a Color correction effect in the effect palette, and work it in the CC Window. Not a Spot color effect. I do not think the process is different.
