  • two colors in cromakey

    Hello,

    Is there a chance to remove two colors with the edius chromakey?

    Thanks a lot

    Have you tried applying multiple chroma key filters?

    Alternatively, you could use Chrominance to change all the knockout colors to one color, then have the chroma key to pull the one color.

      Hi Brandon

      my version of Edius does not allow me to add more than one keyer

      do you have a newer version?

        Hmm, maybe I'm daydreaming, but I swear you could do it before...

        Here's a better solution anyway...
        1. Use Chroma Key to knock out the first color
        2. Set Display Key
        3. Export this as matte1
        4. Change Chroma Key to knock out the second color
        5. Export this as matte2
        6. Select both source and matte1 clips in Bin
        7. Right-click one of them and choose Convert|Alphamatte
        8. Set Luminance key
        9. Set key and fill so it appears correctly
        10. Save as result1
        11. Select both result1 and matte2 clips in Bin
        12. Right-click one of them and choose Convert|Alphamatte
        13. Set Luminance key
        14. Set key and fill so it appears correctly
        15. Save as result2


        result2 should have both colors keyed out.

            You can always don it on a separate sequence and then do the second color in the nested sequence.

              I really would ask the question what is the intended end result.
              Because I think that this can be easily done in the white balance tool if you use color range and use the limiters for Hue, Sat. and Luminace.
              When using it together with the histogram and key display it is really easy.

              Alas if the intended end result was a color change or mono.

                it did not work in 4.61

                maybe it worked in Edius3, I can't remember

                  Problem is that today the sequence's result loses alpha, so you'd end up with a lot of black that you'd have to key out.

                    the way it will work with a sequence, I tried it

                    1. place bg clip on V1
                    2. place clip to be keyed on V2
                    3. set up key of first color
                    4. add to bin as sequence between in and out (mark in and out first)
                    5. delete clip on V2
                    6. drag sequence from bin to V2 to exact spot where deleted clip was
                    7. add chroma keyer and key out the other color

                      Slick one Anton - essentially you're "committing" the background to the key hole in each step.

                      Much easier for cases where you don't have to change the background.
