| Video Article |  | How to make a time-lapse video with your digital video camera
Getting the most out of your digital video camera can mean being
able to create some really cool stuff. You just have to step
outside the manual a bit and find the cool things you can do
with your digital video camera and your editing software.
We have all seen them in a movie or a TV show, those very cool
shots where they speed up time and capture a long segment of
time and condense it into a very short amount of video. My very
favorite example of this technique was an arty movie of many
years ago that was called Koyaanisqatsi. In that movie they had
some very interesting segments where they did time lapse effects
to show driving on a bridge, flowers growing, clouds flying by
and so on. Another example is many of the TV news stations
nowadays have a camera that captures the day’s weather and then
they process it down to a 20 second clip to show the clouds and
weather racing by on screen.
Well this technique is not just a tool in the hands of the movie
makers or the big TV stations. You can do this with your digital
video camera gear too. I will go into two ways that you can
accomplish this effect and get some cool results for your next
video project. This one is worth playing around with in order to
find the right settings to get the most dramatic effect.
Technique number one is to use the camera itself to do the time
lapse recording for you. Almost all digital video cameras have
the ability to do an interval recording. What this means in a
nutshell is that you tell the camera how long you want to record
for and how long in between recordings and it will go on
autopilot for you for as long as the battery lasts or the tape
runs out. This is what those cameras at the convenience store
do, they record a few seconds of motion every 30-60 seconds
giving the overall view of the traffic in the store over time.
Now if you want to capture some time lapse in your digital video
camera you will need to get into your cameras menu and find
Interval Recording (or in my case Int Rec, as I use a Sony PD
150 for my camera) When you select this option you will decide
how long of an interval between shots you want and how long to
record each time. If you are trying to capture something that
takes a long time to occur and in which not much happens quickly
you will want to set the interval at around a minute and the
record time as short as possible on your camera. An example
would be if you wanted to record a day in the life of a flower
or the clouds rolling by in the sky. Suppose however that you
want to capture an event that has lots of action and occurs over
a much shorter time frame. Then you would want to shorten the
interval between recordings and increase the time of each
recording. So in this case you might record every 15-30 seconds
and record up to 2-3 seconds of video each time.
I used this technique to capture an afternoon of work being done
by a team of carpenters on my house remodeling project. The
result was a flurry of activity as workers raced hither and yon
nailing boards, carrying equipment and building walls. I have
added it to my photo collection of the project. (Hey I had to
live through the project so I might as well have a great record
of it for posterity!)
Now suppose you have one of the great software video editing
packages on your computer to work with your digital video
camera. Now you can do it in post as they say in the business.
You can record any length of video you want (subject to the
limitations of your tape length) and then import it into your
editing program.
Sidebar:
I use Adobe Premiere Pro for my editing jobs, but I have also
used Avid DV Express, Final Cut Pro, and others in the non
linear editing world. These are all great programs and are very
powerful products that can create some very professional looking
videos. You don’t have to have these products to create your own
videos but if you are serious about digital video editing it
might be a good idea to take a look at these options.
I digitize my raw video of the scene I am doing time lapse on
into my computer (big hard drive, video eats up GB’s of space)
and then import the clip into my time line. From th3e timeline
you can then select the clip with a right click. From there you
will be given a menu with options depending on the software you
use. Select the option that says “duration”, “speed” or
something similar. Change the speed of the clip so that time
will speed up considerably. If you have an hour of video in the
clip and want to shorten it to 2 -5 minutes then you need to
increase the speed of the clip to 3 or 4 thousand percent of
normal. This will require your software to render the clip at
the higher speed and may take some time top process depending on
the speed of your computer.
Once you have rendered the video clip at the new speed you will
want to play it to see if the movie flows evenly or if you will
want to readjust the speed setting to make it better. Sometimes
you may want to shorten your raw video and adjust the speed down
somewhat in order to get a smooth flow of action. Once you have
rendered the clip at the new speed you can now cut and splice it
as you see fit with the speeded up action intact. There are some
things you will record that might only need a slight speed
change, take for instance some digital video of your kids
playing sports. Double or triple the speed of the clip and show
it to them and you might have them rolling on the floor.
You can also use these techniques to capture the growth of a
flower or plant over the course of days or weeks. Simply set you
camera in exactly the same place at the same time each day and
record an interval that works each day fro however long you want
to document. May be you get the seedling just breaking soil and
follow it all the way through turning into a full grown plant.
Another interesting idea is to capture the path of the moon
across the night sky. Set up your camera on a tripod in a spot
that can see the path of the moon for several hours. Set the
camera to interval record and put the moon on one side of the
frame so that it will pass across the frame as the night passes.
This one may require some testing in order to get the exposure
and framing right as well as the right interval to record at.
Most likely you would want to set the interval as long as you
can and the record time as short as you can but do a test run
first to see what works.
I can’t stress enough that using your digital video camera can
be great fun and you can achieve some cool results. Play around
and test. You just might find yourself creating some very
creative digital video to share with the rest of the world.
