1. Open
Photoshop use File>Open and
locate the image you would like to edit.

2. Once the image opens make a duplicate of the image so
that you can work on a layer that is unlocked. Go to Layer > Duplicate
Layer


3. Go to Image > Image Size and notice the current aspect ratio of your image.

4. For an image to take up the full screen adjust the
aspect ratio in pixels by clicking in the boxes and changing the pixel values to:
IMOVIE = 720 x 540
FCP
720 x 486

(Note-the constrain
proportions box keeps the aspect ration of height and width the same when
only one of the values is changed. To change just one value and not the other,
click the constrain proportion window off.)
5. Once the size has been
changed, save the changes as a jpeg file by going to File> Save As
and selecting JPEG as the
file format.

6. Now you are ready to
import the file into either Imovie or FCP.
