How to remove transparency of a keyed out object ( green screen )

Hi guys, I just recently started to learn how to key out things from the green screen, unfortunately when I key out an object from its background it becomes slightly transparent, so that when I put a new background, it shines right though the parts of the object :(. Are there any ways to get rid of this transparency? Your reply would be very much appreciated, thank you in advance 🙂

    Entirely depends on your keying settings and what else is going on. Since you haven't shared any eal info like a screenshot with the settings and how it looks in the comp we can't tell you much. If you're e.g. using Keylight it could be as easy as playing with the Alpha rollback values, if it's something else it could be necessary to add an adjustment effect like Levels to manipulate the Alpha/ transparency. Either way, you have to be more specific.

      Yeah I used the "keylight" effect for that, in my case decreasing the "screen gain" option doesn't work since parts of the green screen start to protrude.

      Thank you man, I followed your advice and adjusted the Alpha channel by the means of "levels", and managed to get rid of the transparency, however now instead of the transparency there is a visual noise grid flickering upon the object..

      Are there any ways to get rid of this noise grid?

      Once again thank you for your help! Here are all the screenshots above.

      What effect are you using to remove the background? Even on professionally shot greenscreen footage, I have to fiddle with almost all of the options in Keylight to pull a really good key.

       

      When you have a problem, select the problem layers in your timeline, press the "u" key twice to reveal all modified properties on the layers, then take a screenshot and drag it to the reply field on the forum so we can see what you are dealing with. Don't use the Drag & Drop here button; drag the screenshot directly to the reply field so you can see it, make it big, then describe your workflow and your problem.
