Saving and Adobe Dynamic Link (Adobe Production Studio only)

You must save your After Effects project at least once before you can create a dynamic link from Adobe Premiere Pro
or Adobe Encore DVD to a composition within it. However, you don't have to subsequently save changes to an After
Effects project to see changes to a linked composition in Adobe Premiere Pro or Adobe Encore DVD.
If you use the Save As command to copy an After Effects project that contains compositions referenced by Adobe
Dynamic Link, Adobe Premiere Pro or Adobe Encore DVD uses the original composition—not the new copy—as
its source for the linked composition. You can relink a composition to the new copy at any time (see "To relink a
dynamically linked composition (Adobe Production Studio only)" on page 635).
Managing performance and Adobe Dynamic Link (Adobe Production Studio only)
Because a linked composition may reference a complex source composition, actions you perform on a linked compo-
sition may require additional processing time as After Effects applies the actions and makes the final data available
to Adobe Premiere Pro or Adobe Encore DVD. In some cases, the additional processing time may delay preview or
playback.
If you're working with complex source compositions and experiencing playback delays, you can take the compo-
sition offline or disable a linked clip to temporarily stop referencing a dynamically linked composition (see "To take
a dynamically linked composition offline (Adobe Production Studio only)" on page 635), or render the composition
and replace the dynamically linked composition with the rendered file. If you commonly work with complex source
compositions, try adding RAM or using a faster processor.

Color and Adobe Dynamic Link (Adobe Production Studio only)

Adobe After Effects works in the RGB (red, green, blue) color space. Adobe Premiere Pro, however, works in the
YUV color space. When you work with a dynamically linked composition, Adobe Premiere Pro either converts it to
YUV or retains the RGB color space, depending on the output format.
Dynamically linked compositions are rendered in the color depth of the After Effects project (8-, 16-, or 32-bpc,
depending on Project Settings). Set the After Effects project color depth to 32-bpc if you're working with HDR (high
dynamic range) assets.
In Adobe Premiere Pro, choose Project > Project Settings > Video Rendering, and select Maximum Bit Depth to have
Adobe Premiere Pro process at the highest possible quality. This option may slow processing.
To link to a new composition with Adobe Dynamic Link (Adobe Production Studio
only)
When you link to a new composition from Adobe Premiere Pro or Adobe Encore DVD, After Effects starts and
creates a new project and composition with the dimensions, pixel aspect ratio, frame rate, and audio sample rate of
your Adobe Premiere Pro or Adobe Encore DVD project. (If After Effects is already running, it creates a new compo-
sition in the current project.) The new composition name is based on the Adobe Premiere Pro or Adobe Encore DVD
project name, followed by "Linked Comp [x]. "
In Adobe Premiere Pro or Adobe Encore DVD, choose File > Adobe Dynamic Link > New After Effects Compo-
1
sition.
2 If the After Effects Save As dialog box appears, enter a name and location for the After Effects project, and click
Save.
