Photoshop: December 2013 Archives

Learn how to create the illusion of moving through walls or through a ceiling by creating a full screen moving filmstrip within Adobe Premiere.

premiere_training.pngTo start, navigate to a bin window and select some clip segments you would like to use for the filmstrip.

Hold down the shift key to select multiple segments, and then drag the clips to an empty sequence.

Next, use the keyboard shortcut command A to select all the clips in the sequence.

Then right click on the selected clips and choose Speed / Duration

A Clip Speed / Duration box will appear.

Click on this link icon to disable speed changes.

Type in a duration of 3:00 for your clip segments.

Check the option for ripple edit, shifting trailing clips is selected.

Then press the okay button.

So now, you will have a sequence with all the clips matching the same clip duration.

Deselect the clips in the timeline, and then double click on the first clip within your sequence.

Make sure the playhead indicator is at the first frame of the clip segment.

Navigate to the effect controls tab window, and twirl down the disclosure triangle for the motion parameter.

Click the stopwatch to activate animation for the position parameter.

This will add a keyframe.

Adjust the X position until your picture is off to the right side of the visible picture area.

Then move the playhead indicator to the last frame of the clip segment.

Now adjust the X position until the picture if off to the left side of the screen.

You should now have a clip segment that moves across the screen from right to left.

Navigate back to the timeline window, and press Command C to copy the motion parameters of the first clip segment.

Then select all the other clip segments in the sequence.

Right click on them and choose Paste Attributes from the contextual menu.

A dialogue box will appear.

Make sure the Motion attribute option is checked, and then press okay.

So now, as you can see, all the clip segments move from right to left.

However, we need to close the gaps between them.

To do this, move the playhead indicator in the sequence forward exactly 1 second and 15 frames.

Move the next clip segment up a track to and snap it to the playhead indicator.

Then move all the other clip segments into place by offsetting them by 1 second and 15 frames.

Okay, now you should have a full screen moving filmstrip.

Okay, so now to hide the seam between the clip segments, we'll place a graphic on top of it.

To do that, it's important that your graphic contains something called an alpha channel.  

If you open your graphic into Photoshop, you should see a checkerboard pattern to indicate that it has a transparent background.

Otherwise, you will need to cut out the background to create an alpha channel.

In Photoshop, you can sometimes get lucky and use a simple click with the magic eraser tool to remove the background.

Okay, once that's done, go ahead and edit your graphic onto the V3 track in the timeline.

Make sure the graphic matches the same 3 second duration of all your other clip segments.

Right click on it, and choose Paste Attributes.

Make sure the Motion attribute option is checked, and then press okay.

Next, click on the clip segment containing the graphic and adjust it to the left or right so it lines up on the seam of moving filmstrip.

You can slide the graphic to the left or right by holding down the command key and using the left or right arrows to slide the clip 1 frame at a time.

Then you would repeat this same process for cover up the other seams.
