    Grey Spots on Background After VideoMerge

    DigiWannaBe

      Hi,

       

      I use a green screen, and after applying videomerge to remove the background I often get "grey areas" that persist after applying a new background.  They show up in random locations on the removed layer.

       

      Any ideas that may cause this?  I've tried applying "green screen key" and "chroma key" instead of videomerge, but videomerge doesn't affect the front layer images.

       

      Could this be from lighting?  I've yet to be able to solve this as I've tried, coloring, saturation, etc.  HELP!

          What version of Premiere Elements are you using and on what computer operating system is it running?

           

          When you are using ChromaKey, are you editing the effect with the adjusts in the ChromaKey panel, including Sensitivity?

          Have you sampled various spots in the image as the target of the wanted transparency?

           

          From the screenshot colors that I picking up on, it looks like there are shades of blue as well as green in that image which is

          being grabbed from green screening.

            I'm using 11 and Windows 7.

             

            I'm a newbie here and not a full-time graphic designer.  I'm a real estate agent trying to blog.

             

            I'm using the chroma-key from the panel, but when I use it, it distorts my image and causes a black/white distorted image.  Not understanding the "application of sensitivity" of chroma-key.

             

            Not sure what you mean by "sampling various spots in the image as the target of the wanted transparency."

             

            The videomerge was applied prior to adding the graphs if that is what you are referring to regarding "blue."  I've applied some color and saturation already.  I can easily redo the screen shot without applying any effects if you wish to see that?

              I will be back in a moment. I am preparing some screenshots as a demo for your possible use of ChromaKey for your green screening.

               

              But, I did want to acknowledge a goof in my prior post. I wrote Sensitivity where it should have been Similarity. Sorry about that. Everything else in that post is as written.

               

              More soon.

                  Given you have an image, such as the following and you import that into Premiere Elements 11 on Windows 7 64 bit and obtain your image on a transparent background.

                   

                  1.JPG

                  Highlight the clip, and then fx Effects tab/Keying/ChromaKey at the bottom of the Expert workspace, followed by

                  Applied Effects/Applied Effects Palette/ChromaKey Panel expanded. It should look something like the following in principle.

                  2.JPG.

                  Then, in the ChromaKey options, click on the eyedropper and then on the green on screen (the green

                  that you want to replace with transparency). When you do, you should see something like the following in

                  principle. Remember, Premiere Elements uses black to represent transparency.

                  3JPG.JPG

                  You now have your transparency areas; however probably there will probably be edges of

                  the image that need fine tuning. For that, move the Similarlty slider to the right slowly to the

                  point where you get the cleanest edges around the image.

                   

                  Does any of that help. Or, have you been there and done that already. Complications

                  set in when the image itself has colors similar to the color that you are trying to convert

                  into transparency.

                   

                  ChromaKey should be able to handle a green or blue screening. But, as you know, the preparation

                  of the green or blue screening before it gets into Premiere Elements is critical to success.

                   

                  We will be watching for your results.

                   

                  Thanks.

                      Thank you for all your help.  I will try your suggestions....and for the other input.

                       

                      I'll get back to you ASAP.  I may not be able to get to it today.

                        There are all sorts of variations on this.

                         

                        So, let us see how the prior suggestion fares and then we can decide what next.

                         

                        Thanks.

                          You Sir, are a ROCK STAR!

                           

                          Came out perfectly after the first attempt.  My biggest problem was figuring out how to access the Chromakey options once applied.  Soon as I got that figured out....WHAMO!  My image is a lot better color-wise also.....not enough s/w in the world could make it look good though!

                           

                          Thanks again.
