Short answer: no — not the encrypted ones. TestDisk and PhotoRec are excellent, free, and genuinely useful on Tesla drives. But on encrypted clips — the default on Ryzen-based Teslas since software 2026.20 — they cannot produce a playable video, and the reason is structural rather than a matter of settings or effort.
This page explains exactly where the line falls, so you can tell in about a minute which side of it your footage is on.
What TestDisk and PhotoRec actually do
PhotoRec carves files by checking blocks or clusters for known file signatures. It first determines the block size from the filesystem or from an initial sector-by-sector pass. For an MP4, a key marker is the ftyp box near the start of the file.
That approach is why PhotoRec works so well on a formatted Tesla USB drive. Formatting clears the index, not the data — the clips are still physically present, and carving finds them without needing the index at all. TestDisk is its sibling, aimed at repairing partition tables and undeleting from an intact file system.
Neither tool decrypts anything. That is not a gap in them; it was never their job.
Why an encrypted clip is invisible to carving
On supported cars, Tesla writes each clip as a per-file encrypted container rather than a plain MP4 (the default since software 2026.20). The practical consequence is simple:
An encrypted clip does not begin with ftyp. There is no MP4 there to find. The video only exists after decryption. So a carver scanning the drive does not recover a broken video, or a partial video — it does not see a video at all. The bytes look like noise, because to anything without the key, they are.
You can point PhotoRec at a drive full of encrypted Sentry footage and have it report almost nothing worth keeping. The tool is working correctly. There is simply no MP4 signature on that drive to match.
Why no offline tool can decrypt them either
The obvious follow-up is whether some other free tool could carve the container and then decrypt it. Not without the key, and the key is not on the drive.
Each clip is sealed to your specific vehicle. The private key that unseals it never leaves Tesla's servers, and Tesla releases only one-shot keys for individual files, to an authenticated request. There is no master key stored on the USB stick, no passphrase derived from the drive, and nothing in the container that a local tool could brute force in a useful amount of time.
That is a deliberate privacy design, and it is a good one — it means a stolen USB drive is not a stolen recording of your life. It also means any tool that decrypts your clips must authenticate to Tesla as you. Software that claims to decrypt encrypted clips with no Tesla sign-in at all is claiming something the design does not allow.
So where exactly is the line?
| Your situation | TestDisk / PhotoRec | ClipSalvage |
|---|---|---|
| Clips saved unencrypted, deleted or formatted drive | Yes — free and effective | Yes, with previews and camera labelling |
| Encrypted clips, still on the drive | No — nothing to carve | Yes, after a Tesla sign-in when prompted |
| Encrypted clips, deleted or formatted | No | Yes — carves the encrypted containers, then decrypts |
| Partially overwritten clips | Produces unplayable fragments | Rebuilds them into playable video where possible |
| You want to know what is recoverable before paying | Trial and error | Free scan with per-clip preview and confidence score |
If your footage was saved unencrypted, use PhotoRec. It is free, it is well maintained, and it will do the job. We would rather tell you that than sell you something you do not need.
How to tell which side you are on
- Check the car's software version — Controls → Software. If it has been on 2026.20 or later for a while, recent clips are encrypted.
- Look at the files on the drive. Plug the USB into a computer and open
TeslaCam. If the clips play in any normal video player, they are unencrypted. If they will not open anywhere, they are encrypted containers. - Check the toggle — Controls → Safety → Encrypt Dashcam Recordings. It is on by default from 2026.20, but it can be switched off, in which case new clips are plain MP4s again. Clips already written stay as they were recorded.
Mixed drives are normal and common. A drive that spans the update will hold plain clips from before it and encrypted clips from after, and each needs the appropriate treatment.
What using each one actually feels like
The capability gap above is the important one, but there is a practical gap too, and it is worth being precise about because it is often overstated.
PhotoRec has a graphical option. QPhotoRec is CGSecurity’s official Qt interface and is included in the Windows download. CGSecurity’s macOS instructions describe running PhotoRec in Terminal; they do not promise QPhotoRec in the macOS package. TestDisk uses a text interface. The practical distinction here is the output: PhotoRec does not restore original filenames or group clips by Tesla camera or Sentry event.
The bigger difference is not the interface, it is that carving is blind. PhotoRec cannot tell you what it is about to find. You point it at the drive, wait, and then sort through the result:
- Output arrives as numbered files in
recup_dir.1,recup_dir.2and so on —f0001234.mp4, not2026-08-14_15-22-06-front.mp4. - Original Tesla filenames are gone, so which camera filmed what, and when, is not recoverable from the file itself. You open clips one by one to find out.
- Nothing is grouped by Sentry event, so a single incident's four or six angles are scattered through the output.
- Partially overwritten clips come out as unplayable fragments rather than being repaired.
- There is no way to know in advance whether the clip you care about survived — you commit to the full scan first, then discover the answer.
View available thumbnails and recovery assessments. Recovery assessments help you judge the footage found. Available confidence scores use structural integrity checks; they are guidance, not recovery probabilities or guarantees of perfect playback. Some clips may have no score while assessment is pending. Verify exported footage in a video player.
So the honest summary is: if your clips are unencrypted and you are willing to sift through a folder of numbered files to find the one you want, PhotoRec will get you there for nothing. View available thumbnails and recovery assessments. Decryption of existing encrypted clips is free and unlimited. Existing clips export free when no repair is needed; deleted and repaired clips share 3 free recovery exports. Pro adds unlimited recovery exports. No time limit; repeat recovery exports count toward the allowance.
What ClipSalvage does that a carver cannot
ClipSalvage carves at the sector level like PhotoRec does, but it knows the encrypted container's signature, so it finds clips that have no MP4 header. It then fetches the per-clip keys from Tesla — through a sign-in that happens on Tesla's own page, so the app never sees your password — and decrypts locally on your machine. Your footage, thumbnails and disk contents are not uploaded. Cached keys can avoid repeated requests for the same clips; other recordings may require another sign-in.
It also does the things that matter once you have the bytes back: recovering surviving footage from partly overwritten clips, identifying which camera filmed a clip when the filename did not survive, and offering available recovery assessments to help you select footage to export and check.
The scan and the previews are free. If your clips turn out to be unencrypted, you will see that too — and you are welcome to go and use PhotoRec instead.

On encrypted clips: Tesla encrypts USB clips by default on supported vehicles — those with the AMD Ryzen infotainment computer (Model 3, Model Y, the refreshed Model S and Model X, and Cybertruck) — and every release since software 2026.20 has kept it. On a supported car, every Sentry and Dashcam clip written since that update is an encrypted container unless the owner has switched Controls > Safety > Encrypt Dashcam Recordings off. Clips recorded before the update, clips recorded with that setting off, and clips from cars without the feature (cars with the older Intel infotainment computer, and vehicles in mainland China, where Tesla has not enabled it) are ordinary MP4 files that ClipSalvage recovers as normal; the decryption features simply do not apply to them. Your car’s software version is shown under Controls > Software. ClipSalvage decrypts only clips recorded by a vehicle on the Tesla account that vehicle was linked to at the time of recording: 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.
