  • Selecting Color Correction Filter

    Is there a color correction filter that I can use only to manipulate a color of my choice within a video? I made a video of some kitchen cabinetry. The bottom cabinets are dark blue and the upper cabinets are a very light stained blue. I would like to darken the color on the upper cabinets without darkening the lower cabinets.

    Thank you

    You should use the 3waycolorcorrection filter. That would do it.

      you can also use the chrominance filter, click the light blue to sample the area and then add color balance filter to inside selection

      if you need soft edge, adjust alpha shape

        I would go wih Anton's suggestion, but I would first use a mask around the cabinets you want to change, and then use chrominance inside of the mask.

          Hi student101:
          IF you would try 3wayCC-Filter:

          1) Set the settings as shown in image-Bild-004 (red circles in the lower half)

          2) Hold down SHIFT and click into the REC-Window on some points in the sky to select some blue-colors to be observed by 3wayCC-Filter; then give SHIFT free.

          3) Use the color-wheels (in this case I have used the right wheel - white balance - only) and/or the values to select the color you wish. Try also the saturation and contrast-slider as shown in my example.

          Hint:
          In my example I tried the 3wayCC-Filter without using a mask. But using a mask should be recommended as GV_PS did!
          Image Bild-005/Bild-006 shows the before/after-effect.
          Good luck - kurt

                Is there a way I can make the mask track along with the video?

                  Yes. The amount of keyframing you will have to do will depend on how stable of a shot you are.

                    So in other words Jerry, I would have to keyframe for every frame?

                      Not necessary every single frame. Its dependent of the objectmoving.
                      A first rough approach could be:

                      At each step if necessary do ("binary bisecting method"):
                      1) Set a keyframe at the beginning and at the end and adjust the mask at each keyframe.
                      2) Set a keyframe in the middle and adjust the mask.
                      3) Repeat 2) for the remaining halfs and so on.
                      I hope I could outline the basic principle.
                      Regards kurt

                        You wrote it out very clearly, Kurt. I will give it a try tomorrow and let you know how I make out.

                        Kurt, I have another question just a little bit off-topic. My chrominance icon has a blue check in the lower left-hand corner. When I hover my cursor over it, it says alpha channel not supported. May I ask you what this means?

                        Thank you

                          To give you an answer I need to know if you know what an alpha channel is.

                            Not sure exactly what it is but I know I can control it by going to project settings and clicking on the down arrow and selecting from video channel.

                              I will assume you know what an alphachannel is (its besides the red, green and blue-channel a fourth-black/gray/white-only-channel: black means transparency, white means opacity and grey means some degree of transparency):
                              1) See first screenshot: The clip is in Videotrack-2. The mask in the middle is fully transparent and shows the clip in the lower track V1.
                              2) See second screenshot: The mosaik-filter observes the alphachannel ("the mask") and therefore not only the V2-clip is "mosaiked" but also the clip in track V1.
                              3) See third screenshot: The chrominacefilter does NOT (yet) observe the alpha channel and therefore only the Clip (containing the chrominacefilter) in track V2 is changed but not the clip in track V1.
                              Some questions more?
