Short answer: no — not the encrypted ones. TestDisk and PhotoRec are excellent, free, and genuinely useful on Tesla drives. But on clips recorded under vehicle software 2026.20 or later, 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 recovers files by carving: it reads the drive sector by sector, ignores the file system entirely, and looks for byte patterns that mark the start of a known file type. For an MP4 that marker is the ftyp box in the first few bytes. Find ftyp, follow the structure, write out a 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
From software 2026.20, Tesla writes each clip as a per-file encrypted container rather than a plain MP4. 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 2026.20+ 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 recorded before 2026.20, deleted or formatted drive | Yes — free and effective | Yes, with previews and camera labelling |
| Clips recorded on 2026.20+, still on the drive | No — nothing to carve | Yes, after a one-time Tesla sign-in |
| Clips recorded on 2026.20+, 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 predates 2026.20, 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 is terminal-driven. You run it from a shell and drive keyboard menus — pick the disk, pick the partition type, pick the file system, pick a destination. An official Qt interface called QPhotoRec does ship in the same download, so "command line only" is not quite right. In practice, though, QPhotoRec is the Windows build; on macOS you are working in Terminal, which for a Mac owner who just wants a clip back is a real barrier. TestDisk is terminal-driven on every platform.
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.
ClipSalvage runs the same class of sector-level scan, but shows you the result before you commit: every recovered clip appears as a thumbnail with its camera position, its place in the Sentry event, and a 0–100 confidence score, and where the filename did not survive an on-device model works out which camera filmed it. That preview is free, encrypted clips included.
So the honest summary is: if you are comfortable in a terminal, your clips predate 2026.20, 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. The paid tool is buying you the preview, the labelling, the repair of damaged clips — and, for 2026.20 and later, the only route to a playable video at all.
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. Nothing is uploaded. Afterwards the keys are cached locally and further work runs offline.
It also does the things that matter once you have the bytes back: rebuilding partially overwritten clips into playable video, identifying which camera filmed a clip when the filename did not survive, and scoring each clip so you know what is worth exporting before you pay anything.
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: 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.
