# History and versions

> The project History tab — reel versions with covers, going back with “Make current” and a log of all work on the reel.

Source: https://docs.slicer.media/en/guide/projects/history/

Slicer records every piece of work on a reel: the montage, rebuilds, exports, AI effects, translation, assistant commands, publications. Each successful render becomes a version of the reel — you can go back to it if you like the new one less.

History lives in the **Media** section, **History** tab.

**Demo (iPhone):**

1. Media → History: the “Video versions” strip and the “Log”
2. Tap the “Version 2” cover — a sheet with that version's video
3. Tap “Make current” — the “Restore version 2?” confirmation
4. Confirm — “Version 2 is current now”, the “Current” mark on its cover
5. Scroll the Log: entries with statuses, price and time

## Video versions

The **Video versions** strip shows the covers of all versions, newest first. The current one is marked **Current**; under each — the number, duration and date.

Tap a cover to open a sheet with the version's video and the kind of work that produced it: **First montage**, **Re-edit by the director**, **Export from the editor** and others.

### How to restore a version

1.  Open the version you need and tap **Make current**.
2.  Confirm: the video and the editor go back to this version. The current one stays in the history — you can return to it too.
3.  You will see **Version 2 is current now**, and the log gets a **Version restored** entry.

After restoring, the editor shows that version's document — continue editing from it.

> **Note.** Files are kept for the last 10 versions. Older ones keep their history entry, but you cannot watch or restore them — the sheet says **This version file is no longer kept — we keep the last 10**.

## Log

The **Log** lists all work on the reel, newest first. Each entry shows:

-   the kind of work: **First montage**, **Re-edit by the director**, **Style change**, **Montage retry**, **Export from the editor**, **AI effect**, **Fragment processing**, **Audio extraction**, **Caption translation**, **Dubbing**, **AI assistant**, **AI avatar**, **Social post**, **Director’s version**, **Version restored**, **Captions from speech**, **Face tracking**, **Card from a description**, and for a manual project also **Preparing the files**;
-   the status: **Queued**, **In progress**, **Done**, **Error**, **Cancelled**;
-   details: version number, export file settings, translation language, how many edits the assistant made, the AI effect range, the price in tokens;
-   the date and how long the work took.

An entry with a version opens its sheet. A **Social post** entry for a published reel opens the post on the platform in a new tab.

## Fine points

-   An AI montage delivers one version, checked by the director, and it is current right away. The reel from before a rebuild or retry stays in the history: you can make it current at any time — here or by asking in the [chat with the director](https://docs.slicer.media/en/guide/ai/chat/#versions): “bring back the previous version”.
-   An export creates a new version even if you changed nothing in the editor.
-   Deleting a project deletes the files of all its versions.
-   How the director thought during each montage, why it built the reel this way and what it fixed during the self-check — in the journal of the [chat with the director](https://docs.slicer.media/en/guide/ai/chat/#journal).
