**NOTE** The information described in this section is available only with the new proofing viewer and only when reviewing video and static proofs.

You can view side-by-side comparisons of two proofs. Proofs can be two versions of the same proof, or two completely separate proofs (in the same folder when using Workfront Proof, or in the same document list when using Workfront).

- Navigate to the proof that contains the versions you want to compare, then open one of the versions.

The proofing viewer is displayed. - In the upper-left corner of the proofing viewer, do either of the following to compare the version of the proof you are viewing with another version:
- Click the drop-down menu, then click the
**Compare**icon next to the version you want to compare. The proofs are displayed side by side in the proofing viewer, with the newer version on the right side. - Click the
**Compare**icon in the main toolbar. The proofs are displayed side by side in the proofing viewer, with the previous version on the left side of the proofing viewer.

- Click the drop-down menu, then click the
- Continue with "Using Compare Tools."

You can compare separate proofs directly from the proofing viewer. This functionality is available in both Workfront and Workfront Proof.

Comparing Separate Proofs in Workfront

For information about comparing separate proofs from the document list within Workfront, see the "Comparing Two Proofs from a Document List" section in the "Comparing Proofs within Workfront" article.

Comparing Separate Proofs in Workfront Proof

**NOTE** Consider the following limitations when comparing separate proofs as described in this section:

*The functionality described in this section is available only in the legacy proofing viewer. [Remove this when this is available in the new viewer.]**The proofs you compare must be located in the same folder and at the same level of hierarchy within the folder structure.*

- Open one of the proofs you want to compare in the proofing viewer.
- Click the
**Compare Mode**icon. - Click the folder icon to display other proofs within the same folder.

[Replace screen shot with one from the new proofing viewer when this feature is introduced] - Click the proof that you want to compare with the proof currently open in the proofing viewer.

Both proofs are displayed for comparison in the proofing viewer. - Continue with "Using Compare Tools."

The proofing viewer provides various tools for comparing proofs effectively and efficiently.

Auto-compare does a pixel-by-pixel comparison between two proofs. Any differences detected are highlighted in red in the proof on the left.

Auto-compare is available when comparing both static and video proofs.

To enable auto-compare:

- Begin comparing proofs in either of the following ways: two versions of the same proof, or two separate proofs.
- Compare Versions

For information about comparing two versions of the same proof, see "Comparing Proof Versions." - Compare Proofs

For information about comparing two separate proofs, see "Comparing Separate Proofs."

- Compare Versions
- Click the
**Autocompare**icon.

Any differences between the two proofs are highlighted in red in the proof on the left. - (Optional) Click the
**Switch**icon to change the active side so that differences are shown on the proof on the right side. By default, differences are shown on the proof on the left side. - (Optional) Click the
**Color**icon to change the color and opacity used when to highlight differences.

Comparing Proofs in an Overlay

Overlay comparison enables you to view differences between two proofs by viewing the two proofs as a single proof, while providing a vertical divider down the center of the proof. As you pan the proof across the vertical divider, the differences are displayed.

Overlay comparison is available only when comparing static proofs; it is not available when comparing video proofs, or when comparing a video proof and a static proof.

To enable overlay comparison:

- Begin comparing proofs in either of the following ways: two versions of the same proof, or two separate proofs.
- Compare Versions

For information about comparing two versions of the same proof, see "Comparing Proof Versions." - Compare Proofs

For information about comparing two separate proofs, see "Comparing Separate Proofs."

- Compare Versions
- Click the
**Overlay**icon.

The two proofs are displayed as a single proof, with a vertical divider down the center of the proof. - Do either of the following:
- Pan the proof across the vertical divider. As you pan, you see the proof on the left on the left side of the vertical divider, while the proof on the right is displayed on the right side.
- Move the vertical divider to the left and right. As you move the divider, you see the proof on the left on the left side of the vertical divider, while the proof on the right is displayed on the right side.

Simultaneous Navigation Comparison

Simultaneous navigation is enabled by default when comparing proofs. It is available when comparing a static proof and a static proof, or when comparing a video proof and video proof. It is not available when comparing a static proof and a video proof.

**Static proofs:** When enabled on static proofs, simultaneous navigation locks the zoom level and position of the two proofs when panning or scrolling. When a proof contains multiple pages and simultaneous navigation is enabled, changing pages in one proof results in the page changing in the other proof.

**Video proofs:** When enabled on video proofs, simultaneous navigation remembers the time difference on the timelines of the two proofs.

To enable simultaneous navigation if it is not already enabled:

- Begin comparing proofs in either of the following ways: two versions of the same proof, or two separate proofs.
- Compare Versions

For information about comparing two versions of the same proof, see "Comparing Proof Versions." - Compare Proofs

For information about comparing two separate proofs, see "Comparing Separate Proofs."

- Compare Versions
- Click the
**Simultaneous Navigation**icon. - (Optional) Click the Reset icon at any time to reset the zoom level and position (for static proof) or the timeline (for video proofs).

- Close the proof that you no longer want to view by clicking the (x) icon in the upper-left corner of the proof.

The proof that you do not close remains open in the proofing viewer.
