Chromakey-matting with CutOut

In order to crop objects with a monochrome green or blue background in CutOut 9 professional using chromakey-matting, select the desired image in album-mode and click on chromakey in the menu bar. The selected image should now be opened in the chromakey-matting menu as follows:

Now, you have various matting setting-options at your disposal on the right side of the screen, and you can use them to optimize the result.

In order to crop the people in the picture, i.e. to extract the green background, first click on the pipette-symbol: Then click on a spot in the image that corresponds to the background color, in this case a green area.

Using the pipette-tool gives CutOut 9 professional information about which color corresponds to the background.

CutOut 9 professional automatically detects which areas need to be extracted from the image and which need to be retained.

The result is displayed directly, whereby the distant background is displayed transparently (gray-white grid-pattern):

Since the green background in this picture stands out very clearly from the object (the people), the matting result is already pretty ideal and hardly needs any further improvement.

However, one is not always lucky enough to deal with such clearly distinguishable background colors, so that the matting result can often be improved further. In this case, please turn to the chapter chromakey-matting-optimization, which explains the other tools of the chromakey-matting menu

To create the displayed matting result as a separate layer in CutOut 9 professional and then edit or save it, click "Apply" in the chromakey-matting menu.

As a result, the post-matting menu will appear, presenting an array of options on how you can proceed with the cropped object.

To have your cropped object remain as its own layer, please select the option "Duplicate Layer".

Further explanations regarding the remaining menu options can be found in the chapter titled "The Post-matting Menu".

The matting result is now available in the menu bar on the right in the layers-area.

In order to recognize the matting result, however, you must hide the layer of the original image that still contains the background.

You can do this by clicking on the “eye symbol” next to the layer:
