Common problems

Lost work after a frozen save? Project recovery for editors

Your editor froze mid-save or a project won't open. How to recover the cut, the auto-save and backup settings to fix today, and habits that prevent a repeat.

If your editing app froze while saving, or a project now refuses to open, stop working in that file. Do not save over it, do not let the app "repair" it in place, and do not empty the trash. Copy the whole project folder somewhere safe, then look for the most recent auto-save or backup, which almost every NLE writes to a separate folder. In most cases the cut is recoverable to within minutes of the crash.

The rest of this guide covers recovery step by step, the settings that make the next freeze cost minutes instead of days, and how cinemaOS approaches project safety. Editors report this problem across Premiere Pro, Resolve, Final Cut and others, so the advice is written to work regardless of the tool you use.

First hour: recovering what you can

Work through this in order. Each step protects the evidence for the next.

  1. Duplicate before you touch anything. Copy the project file, its auto-save folder and any cache or library bundle to another drive. Every recovery attempt happens on the copy.
  2. Find the auto-saves. Premiere Pro keeps them in an Auto-Save folder beside or inside the project location set in preferences. Resolve keeps project backups in a location set under its project save and load preferences. Final Cut libraries keep their own backups, by default in a Final Cut Backups folder in your Movies folder. Sort by date modified.
  3. Open the newest auto-save as a new project. Do not rename it over the original. If it opens, immediately save it under a new name.
  4. If the newest one fails, step back one. Corruption often lands in the last write. The auto-save from ten minutes earlier is usually clean.
  5. Try an interchange export from any copy that opens. If a damaged project opens but behaves strangely, export an XML, FCPXML or EDL of the sequence and import that into a fresh project. You lose effects, but you keep the edit decisions, which are the expensive part.
  6. Relink, do not re-import. Media is rarely damaged in these events. Point the recovered project at the original files.
  7. Write down what happened. The time of the freeze, what you were doing, how much disk space was free. Patterns show up quickly.

If nothing opens, check whether the drive itself is healthy before blaming the software. A failing external drive can look exactly like a corrupted project.

Auto-save settings that actually protect you

Default auto-save settings are often tuned for convenience rather than safety. Review these today.

  • Interval. Every 5 to 10 minutes is sensible for active editing. Every 15 or more is a long time to lose in a dense session.
  • Number of versions kept. Keep at least 20 to 50. A low count means a bad save can cycle out every good one before you notice.
  • Location. Put auto-saves on a different physical drive from the project if you can. If the project drive fails, the auto-saves survive.
  • Cloud-synced folders. Be careful saving live projects into a folder that a sync client is busy uploading. File locking and partial syncs are a common cause of strange project states. Sync the backups, not the working file.

Versioned saves and media management

Auto-save is a safety net. Deliberate versioning is a method.

  • Save As at every milestone. Film_v012_assembly, Film_v013_finecut. Disk space is cheap; a week of work is not.
  • Duplicate sequences before big changes. Restructuring an act, trying a new opening or locking for colour all deserve a fresh duplicate.
  • Keep projects small. A project with hundreds of old sequences, abandoned generators and unused media saves slowly. Slow saves are where freezes cluster. Archive old material to a separate project.
  • Watch free space. Editors report that saves and renders become unreliable when the system drive is nearly full. Keep comfortable headroom on the project and cache drives.
  • Follow 3-2-1 for anything paid. Three copies, two kinds of storage, one off-site. Back up the project files daily; back up media when it arrives.

How cinemaOS handles project safety

cinemaOS is built on the assumption that something will eventually go wrong, and that the editor should not be the only line of defence. The tools sit under File ▸ Project Safety and in Projects & Recovery (⇧⌘O).

  • Autosave that restores as copies. When you recover from an autosave, cinemaOS opens it as a copy. It never overwrites the project you were working in.
  • Checkpoints. Mark a point you may want to return to, such as "before restructuring act two", in one action.
  • Backups. Back Up Current Project writes a separate copy, and backups are re-validated so you know they can be opened.
  • Version snapshots. Save Version Snapshot captures a sequence state. A comparison sheet shows what changed between versions, so you can see which shots moved rather than guessing from file names.
  • Verified Archive. Create Verified Archive, Verify Archive and Restore Archive package a project for long-term storage and check that it is intact. Consolidate Media Into Project gathers external media when you need a self-contained copy.
  • Project Health (⌥⌘8). A single view of missing media and project issues, next to Missing Media & Relink.
  • Read-only lock. If the same project is already open in another process, it opens read-only. That prevents the classic two-windows-one-file mistake that silently overwrites work.

Two other details matter on a bad day. Undo is 250 steps deep and is stored in the project, so it survives a restart. And projects open, save, back up and relink even without an active licence, so an expired trial or a missed licence check never holds a cut hostage.

None of this replaces a proper off-site backup. It shortens the distance between a freeze and getting back to work.

A weekly safety routine for any NLE

A ten-minute habit beats a heroic recovery.

  1. Save As a new numbered version at the end of each week.
  2. Confirm auto-saves exist and the newest one opens.
  3. Export an interchange file (FCPXML, XML or EDL) of the main sequence and store it with the backups. It is the smallest, most portable insurance you can have.
  4. Copy project files off-site.
  5. Check free space on every drive in the chain.
  6. Delete or archive dead sequences and unused renders.

If your editor has also become unstable after an update, our guide on what to do when a software update broke your project covers freezing versions mid-project. For crash patterns specific to Adobe on macOS, see Premiere Pro keeps crashing on Mac.

FAQ

Can a corrupted project file be repaired?

Sometimes, by opening an earlier auto-save or by importing the project into a new one. The most reliable rescue is extracting the edit as XML, FCPXML or EDL from any version that still opens and rebuilding effects afterwards.

Does auto-save slow down editing?

On very large projects, saves can cause short pauses. The fix is usually a lighter project, not a longer interval. Archive old sequences rather than saving less often.

Is a backup in the same folder enough?

No. A backup on the same drive protects against a bad save, not against drive failure, theft or a sync mistake. Keep at least one copy on separate storage.

Make the next freeze boring

Set your auto-save interval and version count today, whatever you edit in. If you want an editor where checkpoints, version snapshots and verified archives are part of the project itself, try cinemaOS with the 60-day free trial, no card required, and run your weekly safety routine inside it.
