Hi, I'm using Composite Lab Pro -- for the first time. I have set a garbage-matted, and keyed greenscreen clip against a photo.

The keying works well but the outlines of the garbage matte are VERY visible in the project overview and in the rendered and exported clip. It ruins the effect.

I don't seem to have found an adjustment which fixes this.

By the way I'm using the Color Differences filter; but I also have this problem when I use other key filters instead, such as the chroma key filter.

Am I overlooking something obvious?

Please help if you can.

Bonjour

  Avez-vous des Utilise la clé de la valeur?
  C'est très bien pour l'utilisation outlines.Or "supression de Déversement» Dans le «grade» des options de la vidéo:

  -Mat.
  - [Color = red] [/ color] Grade:)
  - [Color = black] [/ color] Animation
  -Mask
  -Composite


  Cette option supprime le contour autour de l'objet sur la greenscreen.

Au revoir


  Ou Utiliser la fonction «valeur intérieure» et la «Plume de valeur" dans votre "Chroma Key".

  Vous Pouvez Suivre les instructions de Vidéos tutoriaux réalisés par Tarn (Simon Jones).

Sorry
my text were in french because I'm french. wink

So You can use(like DVstudio says) spill supression.
For a greenscreen more better, you can use "Key Grade"

You must use the Key adapted.
"auto color difference" or "color difference" is the better for a greenscreen very homogeneous without any fold.

"Grade" and "key Grade" are different.

you should play with the "Key Grade" to improve your greenscreen for a better result.

And....If you can't come to make a good supression.

Use the "Value Key" and little "blur:gaussian" for outlines. It's very nice.

Bye razz

It'd be easier to identify the issue here if you could upload a screenshot or image showing the problem.

CompositeCloneOfMax: As Tarn says, uploading a screenshot or image of the effect will make it much easier for us to see and diagnose the problem.

Use a site like Imageshack to upload the picture, and link to/post it on the forums.
