You've created your filmstrip, and it's almost time to animate it. First, though, you must create an environment for it to run through:
Create a new composition named Master using the Medium, 230x240 composition preset with Duration 10:00 seconds.
Place the Film Strip composition into the Master Timeline starting at time 0:00.
Set the Film Strip layer's Scale to 70, 70%.
To change the duration of the Film Strip layer, select the layer and choose Layer > Time Stretch. Set Duration to 9:29, and click OK.
Still at time 0:00, add the Ch19FinishedProject.mov file to the Master Timeline under the Film Strip layer.
Apply Effect > Blur & Sharpen > Fast Blur to the Ch19FinishedProject layer. Set the effect's Blurriness to 30.
Apply Effect > Adjust > Levels to the Ch19FinishedProject layer. Set the effect's Input White value to 200; this value blows out many of the layer's highlights and helps stylize the video's content.
