I have a question regarding PIP in PD14.

If the subject has shiny spots on their face (usually nose and forehead) the image comes out with patches that are see through.

How do I stop this? (see attachment)

Thanks

The solution is somewhat complicated to explain.

First, make sure you've adjusted all of the slider controls to see if you can find a combination that works. You may also want to try selecting a slightly different spot with the dropper, because a small color change can have a noticeable impact on the overall effectiveness of the chroma key. Don't be afraid to try big steps - just undo if you get too far away from a usable image.

In later versions of PD, you can add multiple chroma keys, which makes it much easier to clean up small areas like that.

You can't do that in PD14, so the next best option is to copy that clip and place it directly below the original one so that they're both synced, and then use the chroma key on the orginal clip to clean up the shiny spots. Since the copied clip lets the background show through, having a synced clip behind it (visually) means that the transparent parts simply show the matching sections from the underlying, synced clip.

The only thing you should have to do is adjust the sliders on the original clip so the shiny areas are solid. You may also want to add a mask (or inverted mask) to one or both clips to keep specific areas from being affected by the chroma key.

Like I said, it's difficult to explain, but if you spend some time experimenting, you should be able to get a clean chroma-keyed image.
