    Antimatte or Paint to create basic mask

    Hi all

    I'm having a nightmare with the most simple mask effects where I want to brighten up a portion of the image by cloning the segment, then using antimatte on the above track. 

    I can apply the colour correction and then use antimatte to create a mask on the higher segment, I can even track the mask using the tracker. It all works well when I place that segment in the timeline on its own, I see the mask doing exactly what I want against a plain black background.

    But the moment I place the untreated cloned segment below it, my color correction effect applies to the whole clip and not just the masked area.  Why is this? What am I doing wrong?

     

    thanks a lot

    try having your backround (ungraded) on V1 and the graded masked section on V3.

    I can't remember if it applied to animatte but from memory sometimes keeping a buffer layer inbetween works.

    If that doesn't work feel free to post a screengrab of the layers and effects and i'll see if i can advise more.

     

     

    If you're on the latest version wtih Symphony you can use shape based correction too directly in colour corrector mode which could also work for you.

    I think you will need to apply your colour correction as part of a nested effect. 

    highlight the clip and then use the 'step-in' command, apply the CC then 'step-out' to see the effect.

    I just took a clip on V1 and duplicated it onto V2. On V1 only, I added a color correction. On V2 clip I dropped an Animatte FX, set control to KEY OUT, then drew a circle from Oval Tool. I saw only the color-corrected V1 inside the circle. Is that useful?

    If you have MC Symphonie option, you will get a "Shape based" color correction option, which would do the job. You can set-up any shape you like and can also apply tracking to it. Color correction is then made inside the shape only.

    Many thanks for the suggestions everyone. The layer 3 idea didn't make any difference but the above one did. I had tried this one yesterday but it didn't work, this time I selected "swap sources" which did the trick.

    If you do not have the symphony mask option the “Spot Color Effect" under image in the effect’s pallet is your fastest and simplest option, Just Alt double click on the spot color effect and make your adjustments.

    I previously used paint but the render time on a single core was way long and I had to duplicate the clip and the existing colour correction onto a new track, the way I did it previously with “paint” was very cumbersome and took for ever render.
