Cinelerra question: How to pan & zoom in a photograph?
Posted by plenty900@yahoo.com on January 24th, 2008


Hi all,

I've been searching for an answer to this question
but can't find it. Can anyone explain it?
I can import a photo just fine as a single frame,
but Cinelerra won't let me do anything with it.

The final video will be 720x480, but the photo
itself is much larger, hence the panning and
zooming.

Thanks.

AKA the "Ken Burns" effect. It's explained in the cinelerra
manual. It's section 21.11 titled "Panning and zooming still
images".

Didn't search too hard, eh?

Laziness is an art form.

It's talk like this that lured me into engineering courses.

If you are going to go as far as listing the "AKA" examle, why not
include the true name for the effect as well? After all, Ken Burns
didn't invent it. He just utilized it a whole lot. Maybe it should be
called "the Traveling Burns", or perhaps "the Ken Matte"!

I knew that.

I guess he was just too lazy to dig up any movie film from the
Civil War. Maybe he could have used some of the extra
footage from Ted Turner's "Gods and Generals". I hear there
was a lot left on the editing room floor -- though not nearly
enough, IMO. I guess the film did get praised for historical
accuracy. Well, both were long, expensive, and painful...

So is the true name the "traveling matte effect"?

In the old days of film editing, it was done with a rostrum camera,
similar to an animation camera or animation stand.
Most NLEs call it a "pan & scan" effect.
AFAIK, only the Mac platform calls it the "Ken Burns Effect".
I wonder if they paid him for that :-)

I see what the "pan" refers to (panning the "camera" across the
source material). To what does the "scan" refer? "pan and
zoom" makes more sense to me, but "pan and scan" rhymes.

Or did he pay _them_?

Wikipedia to the rescue again.
http://en.wikipedia.org/wiki/Pan_and_scan

To broadcast a widescreen film on television, or create a videotape or
DVD master, it is necessary to make a new version from the original
filmed elements. One way to do so is to make a "letterbox" print, which
preserves the original theatrical aspect ratio, but produces an image
with black bars at the top and bottom of the screen. Another way to turn
the wide aspect ratio film into a 4:3 aspect ratio television image is
to "pan and scan" the negative.

During the "pan and scan" process, an operator selects the parts of the
original filmed composition that seem to be significant and makes sure
they are copied—"scanning". When the important action shifts to a new
position in the frame, the operator moves the scanner to follow it,
creating the effect of a pan shot.



Stranger things have been know to happen :-)

Hi all,

If you have questions on cinelerra you can ask them on the irc (irc://
freenode.org/cinelerra). If you are lucky maybe somebody will answer
you quickly.

see you
