The document describes the steps taken to conduct a green screen experiment on a Samsung Galaxy A21s phone. First, background images and music clips were selected. Then, original video footage featuring a green screen was opened in Motion Ninja. Background images were added to the timeline and chroma key editing was used to remove the green screen and reveal the background. Sliders were adjusted to refine the effect and showcase the outlines and visibility of interview subjects against the new studio background.

1. Green-screen experimentation
First I have found and chosen two
images that I wanted in the
background plus two short clips of
two songs that I would use later
on in my documentary interview
Then I got the original
videao and featured the
greenscreen/background.

2. After, I opened motion ninja on the
Samsung galaxy A21s and placed the
original videos on the timeline
I then clicked on the mixer icon
and found my chosen
background which was a image
of a recording studio which was
in JPG file format

3. I then placed the image on the
timeline and dragged it to the
desired length of time
I then clicked edit,
chroma key and I then I
dragged the circle so that
the background can be
seen.
I used the slider tool,
which featured shadow
and intensity
Finally I set drag slider to 100
on shadow to see the outlines
of the host and the guest,
then I dragged the slider to
between 20-30 until I could
see the background
