What changed in Tesla software 2026.20?
Tesla vehicle software 2026.20, rolling out from May 2026, enables USB clip encryption by default. From the moment the update installs, every new Sentry Mode and Dashcam clip your car writes to the USB drive is encrypted. This is a privacy feature: an encrypted clip can't be opened by simply plugging the drive into a laptop, the way an ordinary Tesla MP4 file always could.
The change is silent — there's no per-clip prompt, and the folder layout on the drive (TeslaCam, SentryClips, SavedClips, RecentClips) looks the same as before. What's different is the content of the clip files themselves: they're no longer plain, playable MP4 video.
Why ordinary recovery tools can't read encrypted clips
Recovery tools work by scanning the raw drive for the MP4 signatures that mark the start of a real video file — a technique called file carving. Under 2026.20, each clip is written as a per-file encrypted container instead of a plain MP4: the signatures and the video data behind them are scrambled, and the decryption keys are sealed to the specific vehicle. The keys are held by Tesla and released only to an authenticated Tesla sign-in, so recovering the bytes is not enough on its own — without the keys the footage stays locked. You can't simply copy the clip to another computer and open it.
How ClipSalvage recovers and decrypts encrypted clips (v2.20.0+)
Since v2.20.0, ClipSalvage reads Tesla's encrypted clips and decrypts them back into playable video. The flow, end to end:
- Scan as usual. ClipSalvage finds both plain and encrypted clips on the drive — deleted, formatted, or corrupted alike.
- Preview everything for free. Encrypted clips are decrypted in memory to show a real thumbnail and each clip's true recoverability, so you see exactly what's salvageable before paying.
- Sign in to Tesla once. A one-time in-app Tesla login fetches your clips' decryption keys from Tesla.
- Offline forever after. Keys are stored locally; re-scans and future exports need no internet and no repeat logins.
- Automatic repair. Clips whose data was partially overwritten on the drive are rebuilt into playable video, and each clip is labelled with how much was recovered.
- Export. Save the decrypted, repaired MP4s to a folder. Decrypt up to 30 encrypted clips free; ClipSalvage Decrypt ($9.99, one-time) unlocks batch decrypting and export of every encrypted clip on the drive, and Pro ($29) adds unlimited recovery of deleted and formatted clips on top.
Privacy: the Tesla sign-in is used only to fetch your own clips' keys. All recovery and decryption run entirely on your machine — nothing is uploaded.
Which clips are recoverable?
The dividing line is the moment the update installed — but both sides of it are now recoverable:
- Clips recorded before 2026.20 are standard, unencrypted MP4 files. They are fully recoverable, exactly as before — even from a drive that has since been formatted, corrupted, or had files deleted. Time in a drawer doesn't change this; only new writes do.
- Clips recorded after 2026.20 installed, with encryption on, are encrypted containers. ClipSalvage recovers them and, after the one-time Tesla sign-in, decrypts them into playable MP4s. Partially-overwritten ones are automatically repaired where possible.
Either way, a free ClipSalvage scan will show you what's on the drive — with thumbnails and per-clip recoverability, encrypted or not — before you pay anything.
Should you turn USB encryption off?
You no longer have to for recovery's sake. The setting still exists under Controls > Safety > Encrypt Dashcam Recordings, and the trade-off is now simpler:
- Encryption on protects your clips from being read if the drive is lost or stolen — and with ClipSalvage v2.20.0+, you keep the ability to recover and decrypt them after a format, corruption, or deletion.
- Encryption off keeps clips as ordinary MP4 files that any recovery tool can carve back — but those files can be read by anyone who plugs the drive into a computer.
Decrypting from the car is one-way
There is a third option that is easy to reach for and worth understanding before you use it: the padlock icon in the car’s Dashcam app, which decrypts one clip. Tesla’s 2026.20 release notes describe it as a way to “decrypt a specific clip, making it easier to see the footage if they mount the USB drive to their computer” — that is, the clip is made readable on the drive, not just on the car’s screen.
In our own testing on a 2026.20 vehicle, once a clip has been decrypted this way the padlock for it is gone and the option does not come back. So it is a one-way action, and it has a consequence Tesla does not spell out: that clip no longer carries the protection encryption was added for. Tesla’s stated reason for encrypting in the first place is that a USB drive taken from the car would otherwise expose up to 24 hours of driving — where you live, where you work, when you are away. A clip you decrypted in the car to watch once is readable by whoever ends up with the drive.
That is a fine trade to make deliberately. It is a poor one to make by accident on a drive full of footage. If what you want is playable files on your computer, decrypting from the drive on the computer — with Tesla’s web viewer or a desktop tool — leaves what is on the USB alone.
If you've already lost footage
Stop writing to the drive immediately — don't put it back in the car. Then run a free ClipSalvage scan. Clips that predate 2026.20 are ordinary MP4 files and the scan will find them. Clips recorded with encryption on show up too — previewed free with real thumbnails — and a one-time Tesla sign-in lets ClipSalvage decrypt them into playable video. You can decrypt up to 30 clips without paying anything.
What this means going forward
Encryption doesn't change the physics of the drive — formatted or deleted clips still sit in their sectors until something overwrites them, as covered in what formatting actually does and how long footage stays recoverable. What 2026.20 changes is whether those sectors hold readable video or encrypted containers. For unencrypted clips, everything about recovery works as it always has. For encrypted clips, recovery now takes one extra step — a single Tesla sign-in to fetch your keys — and runs fully offline from then on.

On encrypted clips: decryption applies to clips recorded after Tesla enables software 2026.20 USB encryption in your region. Tesla rolls this out by market, and it is not enabled everywhere — notably not in mainland China. Where it has not been enabled, your clips are ordinary MP4 files and ClipSalvage recovers them as normal; the decryption features simply do not apply. Check what your car is running if you are unsure. ClipSalvage decrypts only clips recorded by a vehicle on your own Tesla account: the keys are held by Tesla and released solely to an authenticated sign-in, so footage from someone else’s car cannot be decrypted by this or any other tool. Recovery of deleted or formatted clips also depends on the sectors not having been overwritten — a drive that kept recording may have nothing left to recover, which is why the free scan shows you what survives before you pay.
