Hello.
I would like to ask a question, for the most knowledgeable. It's clear how to make a chroma key in Powerdirector, simply by applying the chroma key on the background of the video.
How could I go about getting just the opposite effect?
I need only the chromakey part for the effect I want to do, i.e. isolate only one color from the video. Is it possible with powerdirector?

There is likely a way to do it with the new Object Selection tools and a mask.

Thank you in advance for your help. I've tried the effects, but none of them allow me to cut out the part I'm not interested in.
I am going to put an example. In the next video, I would like to cut out the train, not the background. Saying, we would see the train hole.
I think it can't be done with PowerDirector, it would be something like applying a chroma key, and inverting that mask.

The other option is to use ColorDirector. Select the train and track it, and turn the exposure down to 0. Save that back into PD and then you may want to select the black train in the PIP designer Chroma key. I have added a quick-and-dirty attempt here. You may want to include the shadows and do some fine tuning on the edges.
Have fun!
