Chapter 5, Configuring Your DigiSuite LE and VTR Settings
Selecting your editing aspect ratio
To specify the aspect ratio of the material you’re editing on DigiSuite LE,
click the
General tab.
Under
Editing Aspect Ratio
, select the aspect ratio that matches your
source material. For video recorded using the standard TV screen format,
select
4:3
. For video recorded using the wide screen 16:9 format, select
16:9
.
Setting the editing aspect ratio to match your source material’s format
ensures that the effects you create on DigiSuite LE will be displayed with
the correct proportions. If the editing aspect ratio isn’t set correctly, effects
such as circular wipes and borders added to 2D DVEs will be distorted
(that is, squeezed or stretched horizontally). For example, applying a
circular wipe to 16:9 source material using a 4:3 aspect ratio will cause the
wipe to be squeezed into an elongated ellipse.
Remember to create all graphics, animations, and titles for your production
using the same aspect ratio as your source video.
Important
Your new aspect ratio will take effect only after you restart
your computer.
