Editing with Adobe Premiere Pro CS5 if you’re a Final Cut Pro user
How to enable GPU acceleration* for real-time effects:
1. Choose Project > Settings > General.
2. In the Video Rendering section, choose CUDA Accelerated Renderer from the Renderer menu.
With GPU-accelerated effects enabled, a yellow render bar appears when effects are applied to
clips in a sequence with matching footage settings. Note: This function is available only when a
supported GPU-accelerated graphics card is installed.
If you’re working on a computer or laptop editing challenging footage such as high resolution 4K
RED files or sequences with a large number of effects, the Mercury Playback Engine gives you the
ability to adjust the playback resolution of your video in the Source Monitor or Program Monitor.
Separate Playback and Pause resolutions give you more control over monitoring. With high-
resolution footage, you can set playback resolution to ½ for smooth viewing. Setting Pause
resolution to Full allows you to quickly check the quality of focus or edge details when playback is
paused—useful for when you don’t have the luxury of an on-set HD monitor. When working with
higher resolutions, such as RED 4K footage, you can set playback resolution to ½, ¼, ⅛, or 1/16 for
smooth viewing.
To adjust the Playback and Pause resolution in the Source Monitor or Program Monitor
1.
Click the panel menu icon in the upper right
corner of either the Source Monitor or
Program Monitor panel in Adobe Premiere
Pro.
2.
In the pull-down menu, choose Playback
Resolution.
3. Choose ½ resolution.
4.
Repeat step 1, and then set Paused Resolu-
tion to Full.
5.
Play and then pause the sequence.
When playback is paused, you can easily check
the quality of focus and examine edge details by
dragging the scroll bars in the Program Monitor
to the view areas of interest.
Keying with Ultra
Ultra is a powerful high-performance keyer in Adobe Premiere Pro CS5. It lets you achieve fast,
accurate keying on even the most challenging DV and HD footage—footage shot under real-world
conditions typically found in production that include uneven lighting, wrinkled backgrounds, and
frizzy hair. Ultra preserves shadows and can achieve complex keys on smoke, liquids, and
transparent objects. The GPU-accelerated Mercury Playback Engine dramatically increases
rendering speeds, usually resulting in real-time HD keying.
To use the Ultra Keyer:
1. Use the eyedropper control to choose the green or blue background color. Find an area of the
background that best represents the overall background color and not, for example, the middle
of a lighting hot spot or shadow.
2.
For getting the best possible key, you may want to use the different Output viewing modes for
the Ultra keyer. In particular, the Alpha Channel output is useful for detecting unwanted
transparency.
3.
There are 3 presets available - Default, Relaxed, and Aggressive. Try these first before playing
with the sliders - many times one of these presets are enough to pull a clean key.
