I made the video of some interviews. The background was white instead of green or blue. Now i am trying to use the "chroma key" but just part of the background becomes transparent... I use program MAGIX Movie Edit Pro MX Premium. Is there any chance to change the background in this project? Please help.
Hi
Under the Chroma Key 'colors to be hidden' buttons you will see two sliders appear after applying the effect or you click on a clip with the effect already applied.
Adjust the Threshold slider first, and then the Fading Range, if necessary, to adjust the chroma key effect.

Thank you, John! Should i click on white color to be hidden or to pick the color using eyedropper tool? Please advice.
Hi
It depends on how pure the white background is,
Try both to see which gives you what you want - a quick way to reset between testing the effect, is to click the small button top right of the Chroma key pane - the one with the two triangles facing each other point to point.

alinalidina,
I'd suggest at least trying the eyedropper method for comparison. The sliders that John describes are only available for the blue / green / white / black presets and can be very effective. Though the eyedropper color selection doesn't have the slider adjustments it picks the colors a different way and might give you a better results.
The preset for white selects on the basis of 'value' -- you wil make all near white colors transparent irrespective of hue. The eye dripper selects on the basis of hue as well -- you can make warm whites (containing some red) transparent without affecting the cool ones (with a touch of blue).
You can add to an eyedropper selection by holding don the [Ctrl] key and picking again. Note you can't select two different colors; additional samples broaden the range to include all in between. The following image I find useful for observing the effect:
