There are a lot of great royalty-free animated
digital backgrounds available to editors. Some are simple textures. Others are
elaborate 3D graphics loops. Some are available free. Others are worth paying a
few bucks to own. In many situations, these off-the-self digital background
animations may be exactly what an edit needs. I think every editor should have
a bunch of them available to use. But, sometimes a production calls for
something more personal.
Whether you need background for title graphics, or
an animated digital wallpaper to play on screens at a party, creating your own
photo-based animated wallpaper is an attainable option that may be easier than
you think.
Not sure you can do it? Here are step-by-step
instructions to help you pull it off like a pro. We’ll describe how we created
our photo-based animated digital background in this story. With a photo editing
application like Adobe Photoshop and your video editing software you can use
these principles to make your own photo-based motion graphic.
Step
1 – Compile a Photo Collage
To get started, open a photo editing application,
like Adobe Photoshop, and build a photo collage. We used Photoshop for our
example. Since our background was for a high definition video production, we
created a new file at 1920x1080. With the project open, drag pictures from a photo
folder into Photoshop window, one at a time, then scale and position them until
the full 1920x 1080 palette is filled with pictures. Once the collage design is
complete, export a jpeg still of the college.
Step
2 – Build a Big Background
The next ste is to create an extra big still that is
approximately two or three times larger than the resolution of the video
project. In our example, we opened a new Photoshop project window at 3000x3000.
With your big big palette open, drag in the still image of the comp created in
step 1, and slide it into the upper left corner of the Photoshop window. Next,
duolicate the image several times on multiple layers and spread them out to
fill the window. It is okay to overlap and offset them. When the window is full
and you are happy with the look, export a still of extra large 3000x3000 image.
Step
3 – Open Your Video Editing Software and Import the Image
Next, toggle over to your video editing software and
start a new project. We used a 1920x1080 high definition project for this
example. With the project open, import the extra large 3000x3000 still image
that you created in step 2, then drag the clip into your timeline. Stretch the
duration of the clip to length you will need it to be in the edit. For this
example, we set the duration of the clip at 15 seconds.
Step
4 – Scale and Position the Background Image
With the large still image on your timeline, click
on the clip to select it, then open your editing application’s motion controls.
Using your video editing software’s motion controls, zoom in on the big image and adjust the scale and position to
show only the original 1920x1080 still image that was the first image placed in
the upper left corner of the 3000x3000 image in the visible window. The remainder
of the 3000x3000 still will extend beyond the visible area. With the image
scaled and positioned, look back at the motion control settings interface and
click to set a keyframe.
Step
5 – Set the End Position
After you have determined your starting position and
set a keyframe, reposition the big photo to select your endng composition. You
may simply slide the image horizontally, vertically or diagonally. We chose to
set our end frame in the corner diagonal to our starting position. This will
cause the wallpaper to crawl at an angle. With the end position selected, move
the playhead to the end of the clip and click to set a new keyframe. If you
like, you can also experiment with keyframes to simultaneously animate the
scale and rotation of the clip.
Step
6 – Preview the Animation
With the image scaled and positioned, and with start
and end keyframes set, it is time to tap the spacebar to preview the animated
wallpaper. If you are happy with the speed and direction of the movement, it’s
time to move on to the next step. If not, make adjustments to timing and
direction by adjusting your keyframes.
Step
7 – Screen it Back
Since we
intend to put text and graphics on top of the background, it is helpful to
scale back the color. This can be done in your video editing software by
lowering the opacity of the clip. This can be done on the timeline by adjusting
the clip’s handles, or can be entered as a numerical value in the motion
control window. We lowered the opacity of our clip to about 70%. This will “gray
back” the photo wallpaper soit won’t complete with top-layer graphics.
Step
8 – Add Graphics
The final
step is to create a title graphic to position over the animated wallpaper. For our
example we returned to photoshop, where we created our text over a star icon,
and added a few more photos with white outlines to make them look like
old-school snapshots. We than exported our title graphic as a .png file, to
preserve the transparency of the background layer. Next, open the title in your
editing application and layer it on a video track above the animated wallpaper.
If you like, add keyframe to the title layer to add some “grow” and rotation.
