Small problem with framing!

After Mary our other media teacher watched our rough cut she noticed that all our shots from the white room location had a small black frame around it, due to the fact that it got converted into a different format, therefore Mickey our technician showed me the steps to taking it away.

 First i had to double click on all the white room shots one by one and went to the motion bar, clicked the scale number from 100 to 104. This was something very easy to do in my free period lessons however very long. But now all shots are the same framing and not half with black frames and half without. I also experimented with filters and speed and drop shadow just to see what shots would look like.
