Workflows and system setup

Saving and Dynamic Link (Production Premium or Master Collection only)

You must save your After Effects project at least once before you can create a dynamic link from Adobe Premiere Pro
or Encore 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 Encore.

If you use the Save As command to copy an After Effects project that contains compositions referenced by Dynamic
Link, then Adobe Premiere Pro or Encore 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.

Performance and Dynamic Link (Production Premium or Master Collection
only)

Because a linked composition may reference a complex source composition, actions you perform on a linked
composition may require additional processing time as After Effects applies the actions and makes the final data
available to Adobe Premiere Pro or Encore. 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 composition
offline or disable a linked clip to temporarily stop referencing a dynamically linked composition, 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 Dynamic Link (Production Premium or Master Collection only)

After Effects works with the RGB (red, green, blue) color model. Adobe Premiere Pro, however, works with the YUV
color model. When you work with a dynamically linked composition, Adobe Premiere Pro either converts it to YUV
or retains the RGB colors, 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. However, this option may slow processing.

Create and link to After Effects compositions with Dynamic Link (Production
Premium or Master Collection only)

Create a composition from clips in Adobe Premiere Pro

You can replace selected clips in Adobe Premiere Pro with a dynamically linked After Effects composition based on
those clips. The new composition inherits the sequence settings from Adobe Premiere Pro.

In a sequence, select the clips you want in the composition.

Right-click any of the selected clips.

Select Replace With After Effects Composition.
