Chapter 5, Defining Your Adobe Premiere Settings
Selecting your editing aspect ratio
To specify the aspect ratio of the material you’re editing on Matrox RT.X100
Xtreme:
1 Choose Project > Project Settings > General.
2 Click the Advanced Settings button.
3 Under Editing Aspect Ratio on the General page, select the aspect ratio
that matches your source material. This ensures that your effects will be
displayed with the correct proportions.
$ 4:3 Select this if your video was recorded using the standard TV screen
format.
$ 16:9 Select this if your video was recorded using the widescreen 16:9
format.
¡Important If the editing aspect ratio isn’t set correctly, certain effects may
appear distorted (that is, squeezed or stretched horizontally). Make sure you
create all animations, titles, and graphics for your production using the same
aspect ratio as your source video. For example, when creating your own
organic wipe patterns for use in a widescreen production, make sure you
create your organic wipes with a 16:9 aspect ratio. For more information, see
“Creating a production in 16:9 format” on page 77.
4 Click OK to return to the Project Settings dialog box.
Switching between scrubbing types
When you play back the Timeline, both fields of each frame are displayed. When
you scrub the Timeline, however, only one field is displayed. As well, only one
field is displayed when you pause or stop playback on the Timeline. For example,
if you see a “glitch” in your project when you play it back from the Timeline, but
notice that when you scrub on the Timeline to find the glitch, you can’t find it,
you may need to switch the field you’re scrubbing over. You can then return to
your Timeline and find the problem by scrubbing.
°To change your scrubbing type:
1 Choose Project > Project Settings > General.
2 Click the Advanced Settings button.
