Take a movie of a location and a movie shot in front of a green screen and use chromakey to blend the two movies together.

What will be an ideal response?

```
import os
def combineTwoVideos(directory, videoDirectoryOne, videoDirectoryTwo):
frames = []
#Grab all the frames of the first video
for frameFile in os.listdir(videoDirectoryOne):
if frameFile.endswidth(".jpg"):
frames.append(makePicture(videoDirectoryOne+"//"+frameFile))

num = 0
for frameFile in os.listdir(videoDirectoryTwo):
num = num + 1
printNow("Frame: "+str(num))
if frameFile.endswith(".jpg"):
frame=makePicture(videoDirectoryTwo+"//"+frameFile)
for p in getPixels(frame):
if distance(getColor(p),green) <= 100:
setColor(p,getColor(getPixel(frames[num],getX(p),getY(p))))
writeFrame(num,directory ,frame)
```
