Technique: Creating Custom-sized Sequences

You may have heard that Final Cut sequences can be customized. But
what you may not know is how significantly you can make changes --
as long as you don't want to play the results on a DVD or record them
to video tape.
However, since more and more material is moving directly to the web,
the ability to create eye-catching video using Final Cut in non-standard
ways is worth exploring.
So, let's make a giant turn off the straight path to video output
and see what we can do to make things more interesting.
First, keep in mind that in order for a video to play on the web,
it needs to be compressed. Specifically, compressed using the H.264
codec. This means that all we need to do in Final Cut is to create
the master file that will then be compressed for
the web.
Also, within Final Cut, as soon as you move away from standard video
image sizes, you'll need to render -- but, if you were to create a
special effect in After Effects, you'd render there, too. Think of
this as another of Final Cut's special effects and don't let the rendering
deter you.
Let's create a long, horizontal clip of a train running through
an entire valley. The shot we are going to use was shot on
a misty morning along the Amtrak line near Pismo Beach in California.

Here is a standard DV clip. As we know, a DV image is 720 x 480. But,
what happens if we change that.
Start by going to Sequence > Settings.

First, change the Aspect Ratio pop-up to Custom (not Custom 3:2).
Then, change the image size to something unusual -- in this case,
I'll use 720 x 200. That keeps the horizontal part of the image, but
severely crops the vertical.
Note: Final Cut sequences have a maximum dimension
of 4,000 pixels on a side.
Since I'm working with DV video, I'll leave the Pixel Aspect Ratio
alone. I don't want to change the shape of the video pixels, merely
the shape of the sequence it plays in.
Next, change the Compressor to Animation. This codec is the highest
quality codec you can use in Final Cut. The only problem is that is
generates HUGE file sizes and, in most cases, can't be played in real-time.
However, since this will be compressed for the web, which WILL allow
the clip to play in real-time, we don't care about real-time playback
in FCP.
Click OK to save your changes.

Note the entirely different look of the Canvas! Now, when we edit
our video into the timeline, watch what happens.

Hmm... we get a dialog. In this case, we do NOT want to change the
sequence settings to match the video. Click No.

Hmmm..., again. Now our video looks severely pillar-boxed. That's
because whenever the image size and sequence size don't match, Final
Cut will always scale the image so that the entire image fits into
the sequence.
In this case, we don't want that. We need to enlarge the image so
that it completely fills the sequence.

So, double-click the clip in the timeline to load it into the Viewer,
click the Motion tab, and change the scale to 100%. (In our case, the
scale was reduced to 41.67% in order for the entire image to fit.

The last thing we need to adjust is the vertical position of the image.
Because we don't see the entire image, we may need to tweak it so that
the best part of the image fits into our new frame.
In this case, I need to the train a bit so that it doesn't disappear
under the bottom of the frame.
Do this by changing the Center settings
in the Motion tab. The left box controls horizontal position. Set this
to 0 so that the image doesn't move horizontally. Change the right
box to move the train up or down until it fits the best in the frame.
In this example, I raised it 68 pixels.

Here's our finished video in a custom-made sequence.
Cool!
If you want to see this in motion, you can either render it - which
because we are using the Animation codec may, or may not, play on your
system. Or, what I tend to do, is put the playhead where I want playback
to start and press Option+P.
This plays a sequence that requires rendering, without first rendering
it. (It is slower than real-time, but it still plays!)

For instance, here is a sequence I created that is 1,440 x 200 pixels.
In this case, I stacked two clips above each other, and moved the Center
point of one to fill the left side of the sequence, while other clip's
center point was moved to fill the right. I then adjusted the vertical
position so the tracks matched.
Note: This was actually two different trains, shot
at different times, which you can tell because the train on the right
ends before the train on the left.

So you can see the results for yourself, here's
a movie of our 720
x 200 sequence. (Silent -- TRT: 0:37 4 MB -- this may take a few moments
to load.)

Even more dramatic, here's
a movie of our 1440 x 200 sequence. (Silent --
TRT: 0:15 1.8 MB)
Both movies were compressed exporting out of QuickTime using
the H.264 codec.
Imagine what you could do with movies shaped like this -- or any other
size -- on your website - or in digital signage - or on any computer
monitor! Just remember, you can't play movies like this on a TV set.
This is fun!
