Green screen with dust and smoke

[Vespertine32]

I have been trying to make a video with explosions on green screen but the software does not want to remove the green background on dusts, smoke and shades.

 

Below is a video example

Hi

 

The actual shade "green screen" uses is important. You have set basically 100% green with 255. (The default.) This means that in your example the only shade that will be removed from the overlay clip is pure GREEN. Any other shade, even slightly different will remain. So if the clip shows a colour change from pure green for any area, this will not be removed. Did you use the colour picker to choose the best shade? With the Green screen window up, move the mouse cursor over to the preview screen (undocked and enlarged if necessary) and you will see it is now a sampling pipette. Click to choose the exact colour you want to remove and check the effect.

 

Try using a little fading and increasing the threshold as well.
