# Version Stacks

> Organize revisions, compare cuts, and keep feedback connected to the correct version.

<iframe src="https://app.aspect.inc/share/00169744-5f7a-4e9c-8a62-0169de41dfc1/embed?controls=true&autoplay=false&loop=false" loading="eager" title="Version stacking, version 2" style={{ width: "100%", aspectRatio: "16 / 9", border: 0, borderRadius: "12px", overflow: "hidden", display: "block", background: "#000" }} allow="autoplay; fullscreen; picture-in-picture" allowFullScreen />

Version stacks group revisions of the same asset into one item. Reviewers can open earlier cuts, compare two versions, and see the feedback attached to each review round.

## Create and update a version stack

<Steps>
  <Step title="Upload the revisions">
    [Upload each cut as a separate asset](/docs/getting-started/uploading-and-organizing) in the same project or directory, then wait for the uploads to finish.
  </Step>

  <Step title="Create the stack">
    Drag one revision onto another related asset. Aspect groups them into one version stack.
  </Step>

  <Step title="Add later revisions">
    Upload the new cut, then drag it onto the existing stack.
  </Step>

  <Step title="Check the default version">
    Open the stack and confirm that the intended latest revision appears first.
  </Step>
</Steps>

## Manage versions

Open the stack's version controls to view, reorder, or remove revisions.

* Select an earlier revision and view its review activity.
* Reorder versions so the intended revision opens by default.
* Remove a version that was added to the wrong stack.

Removing a version from a stack makes it a standalone asset again. It does not permanently delete the file.

## Compare two versions

Use comparison mode to review two cuts side by side and check changes to editing, graphics, color, audio, captions, or client revisions.

<Steps>
  <Step title="Open the stack">
    Open the versioned asset in the viewer.
  </Step>

  <Step title="Choose Compare">
    Start a comparison and select the earlier and newer revisions.
  </Step>

  <Step title="Review the changes">
    Inspect both versions side by side before starting another review round.
  </Step>
</Steps>

## Feedback stays with its version

Comments, annotations, attachments, replies, and resolved conversations remain connected to the version where they were created. Moving between versions shows the feedback for the selected revision instead of mixing review rounds together.

## Share a version stack

You can send versioned media to external reviewers with a share link.

Before sending it:

1. Confirm that the intended revision opens by default.
2. Choose whether recipients can comment, download, view metadata, or access earlier versions.
3. Test the link before sending it.

<Warning>
  Do not assume every recipient should see earlier cuts. Review the link's permissions before sharing a version stack with a client.
</Warning>

<Card title="Sharing and permissions" href="/docs/share-and-present/sharing-and-permissions">
  Create secure review links and control what recipients can view or do.
</Card>

## Important behavior

* Version stacks are for intentional review rounds, not file backup or recovery.
* Saving over a working project file does not automatically create a new version in the stack.
* Review activity remains attached to the relevant revision.
* Archived versioned media remains available for browser review, comments, metadata, AI Search, and share links.
* Mounted-drive access requires Active Storage. Archiving a project leaves its storage tier unchanged; see [storage tiers and archiving](/docs/concepts/core-concepts#archiving-a-project).

<Note>
  Contact Aspect support if you need help recovering an earlier saved state of a working file.
</Note>

## Best practices

* Keep only related revisions in the same stack.
* Confirm the latest version before requesting review or sharing.
* Compare the new cut with the previous review round.
* Keep earlier versions when their feedback provides useful context.
