PrP - Additional Processes - Create Backfill for Smart Phone Footage

This process will create a dynamic backdrop to fill a 16:9 screen when using vertically filmed smartphone footage

Of course the best advice is this:

But, if you forgot to turn your phone the right way, follow the steps below.

Once you have imported your smartphone media into Premiere

set your IN and Out Points

select Video Track 2 (V2) as your destination track by clicking the box next to the Padlock icon on V2.

Once activated it becomes blue.

Insert your clip in to the timeline

If required, scale the clip down to fit the screen.

Click the clip you've just inserted to select it and then click the 'Effect Controls' Tab.


Adjust the Scale until the whole vertical clip appears in the Program window.

Next, select Video Track 1 (V1) as your destination track.


Ensure the timeline cursor is placed at the head (start) of the clip you just inserted.


Copy + Paste (select clip, Cmd + C then Cmd + V) the clip from V2 onto V1.


Now you have the exact same clip on top of each other in V1 and V2.


Double click the clip in V1 to open it in Source monitor.

In the Source Monitor, click the 'Effect Controls' tab.


Scale the clip from V1 up until it fills the entire screen in the Program window.





You should now have your full vertical smartphone video clip, with a background of the same clip but scaled up, like in the illustration.

Next, in the Project monitor, click the 'Effects' tab. Now you will apply a blur effect to the background image.


Navigate to the Gaussian blur effect.


Drag and drop this effect onto the clip in V1.


Click the clip to select it. Go back to the 'Effect Controls' tab in the 'Source' monitor.

Adjust the 'Blurriness' until you reached the desired result.

At this stage your completed effect should look like this. When you hit play, you will see how the foreground and background images are synched in motion and time, creating the illusion that the whole screen is filled with moving footage.


To provide a subtle separation of the foreground image form the background, follow the steps below.

Apply the 'Drop Shadow' effect to the clip in V2

In the 'Effect Controls' tab, adjust the settings as desired.

A soft shadow some distance from the image seems to work best.

This is the end product.

ADD TEXT

At this stage you can go in and add text to the image if that is what you want, or you can carry on editing your assignment.
