To recover BRAW files properly you need to know what a BRAW file is, and that is where most advice stops being useful. Blackmagic RAW, RED’s R3D, and ARRIRAW do not package a shot the same way: one is a single file with internal checksums, one arrives as a set of segments, and one has no wrapper at all, only a numbered folder of frames. Each design produces a different unit of loss, and that unit decides whether a failed card costs you six seconds or six takes.
The workflow below assumes the media has already been imaged once. If it has not, stop reading and do that first: a cinema card that is degrading will not survive a dozen scan attempts, and the first pass is the one with the best chance.
Why Cinema RAW Recovery Starts With the Media, Not the Format
Everything format-specific comes after a format-independent step. Get an intact copy of the file off the card before deciding what is wrong with it.
Cinema media fails in three ways, like any other card. A logical failure — a deleted file, a quick format, a damaged file system — leaves the recorded data in place, so a scan of the media or of its image recovers complete files. A read failure produces a file that copies but carries corrupted bytes, and the fix is to re-read the affected ranges from the image rather than repeating the whole copy. A physical failure — a controller that no longer responds, cracked media, water ingress — is a laboratory job, and no software changes that.
That boundary matters, because cinema shoots generate the most pressure to cross it. A damaged REDMAG or Codex card is not a software problem, and software recovery versus a recovery lab sets out where the line falls. The handling of production media in general is covered in cinema camera storage recovery.
Two notes before the format-specific work. Cinema cards are usually reformatted between rolls, and a camera format rewrites the file system rather than the data, so a card “wiped” on set yesterday is often fully recoverable today. And verification of recovered files matters here more than anywhere: a restored clip must be checked before anyone grades it.
BRAW: Checksums Turn a Guess Into a Measurement
Blackmagic RAW is the most recoverable of the four, and the reason is not that it is simpler but that it is self-describing. A .braw clip carries embedded checksum data and a frame-based index, which means the file can be verified rather than assessed by eye.
In practice: open the working copy in DaVinci Resolve or the Blackmagic RAW Player and verify the clip. The result is a frame range, not an opinion. A clip that fails on frames 1,240 through 1,410 is a clip with roughly seven seconds of suspect material at 24 fps, and everything outside that range can be treated as intact.
That measurement changes the recovery decision in two ways.
It separates a bad read from lost data. A checksum failure caused by a failing card is a read problem: the bytes may still be correct on the media, and re-reading those specific ranges from the image often returns clean data on the second or third attempt. A checksum failure caused by overwritten sectors is a data problem, and no number of attempts will help. Distinguishing the two is the single most valuable thing a checksum can do, and it is also where people misread the result. A failed check is not a verdict; it is a location.
It bounds the loss precisely. With the affected range known, the conversation with a director starts from a number. Ranges that pass need nothing done to them, and only the failing ranges must be located on the media and re-read, turning a full-card scan into a targeted operation.
What checksums cannot do is create data. If the frames are gone because a later recording reused those sectors, verification will report the failure correctly and that is the end of the story.
| Format | Wrapper | Recovery unit | Partial recovery | Primary vendor tool chain |
|---|---|---|---|---|
| Blackmagic RAW | Single .braw file with embedded checksum and frame index | A frame range that fails verification | Yes: everything outside the failing ranges decodes | DaVinci Resolve, Blackmagic RAW Player, Blackmagic RAW SDK |
| REDCODE RAW | .R3D clip, internally segmented, with older media using .RDC continuations | One segment of the clip | Yes: the clip decodes up to the damaged or missing segment | REDCINE-X PRO, RED SDK, manufacturer media recovery service |
| ARRIRAW | Folder of individual frame files plus an XML sidecar | Individual frame files at known numbers | Yes: a gap at exact frame numbers, and nothing more | ARRI Reference Tool, ARRIRAW Converter, vendor SDK |
| ProRes | Single .mov, intraframe | A short run of frames around the damage | Yes: damage is spatially and temporally local | Standard NLEs, remux, and general container repair tools |
R3D: Recovering Segments Without the Ones You Lost
REDCODE RAW is built from segments, and that structure is the whole recovery story. On media formatted with FAT32, long clips were split at the 4 GB ceiling into a main .R3D file plus one or more .RDC continuation parts. Modern high-capacity media removed the file splitting, but the internal segmentation remains, because it is part of how the codec is written and read.
The consequence for recovery is that a damaged R3D is usually a damaged segment, and the rest of the clip is intact. That is good news with one important qualification: the boundary is not visible in the file size or the file date. Finding which segment failed requires reading the clip’s internal structure, and the practical approach is to open the clip in REDCINE-X PRO and step forward until decoding stops or artifacts begin. Everything before that point can be exported as a usable master.
Three rules cover most R3D recoveries.
Collect every part before judging the clip. If the recording came from an older CF-based shoot, a lone .R3D may be incomplete rather than short. Verify that every continuation file arrived before concluding anything.
Export the intact portion immediately. Once you know where decoding stops, export what works to a new master. That converts a fragile recovery into a stable deliverable and stops the experimenting.
Do not expect third-party repair tools to reconstruct the codec. REDCODE is a proprietary wavelet-compressed stream, so the only fully correct decoder is the vendor’s own. A general video repair utility cannot rebuild it from first principles, and time spent there is time not spent on the vendor path.
If an R3D clip is unreadable at the file level and the media itself is suspect, the manufacturer’s own media recovery service exists for that situation. It is a vendor channel, not a software one, and it belongs in the plan before a shoot rather than after one.
ARRIRAW: Rebuilding a Frame Sequence and Its Sidecar
ARRIRAW breaks the assumption that a shot is a file. A recording is a sequence of individual frame files — typically .ari — stored in a folder alongside an XML sidecar that describes the sequence, the color transform, and the clip metadata. The camera writes frame 1, frame 2, frame 3 as separate objects.
This makes ARRIRAW simultaneously the most fragile and the most predictable format to recover. The fragility is that loss is quantized to frames: a damaged sector costs you exactly the frames stored on it, and a gap of three seconds in the middle of a slow push-in is unrecoverable as a shot. The predictability is that the failure mode that dominates consumer video — a complete set of frames with a missing index — does not exist here. There is no moov atom to lose.
Recovery therefore has three steps, in order.
- Recover the frame files and count them. The numbering tells you immediately what is present and what is missing, which is a faster diagnosis than any tool can give you.
- Rebuild the sequence. ARRI’s own tools and the ARRIRAW Converter expect a sequence, and a recovered folder that plays as individual stills needs the XML restored or recreated so that post can conform it into a clip. Recreating the sidecar by hand is tedious but straightforward: frame rate, color transform, and clip metadata are recoverable from the remaining frames and the production notes.
- Document the gap by frame number. Telling an editor that frames 0042 through 0115 of take 7 are gone is actionable; telling them a clip is damaged is not.
The sidecar is small and it should be the first thing to leave a marginal card, for the same reason sidecars matter in every workflow: cheap to copy, expensive to reconstruct. The same principle applied to stills is why an embedded preview can rescue an image whose RAW data is partly damaged, as described in RAW photo recovery.
ProRes Masters: The Format That Tolerates Partial Damage
ProRes is not RAW, and it is included here because most cinema workflows produce a ProRes master somewhere in the chain, and because its recovery behavior is genuinely different.
ProRes is intraframe: every frame is compressed independently, with no dependence on its neighbors. That single property makes partial recovery the default rather than the exception. Corruption in an intraframe file affects a short run of frames around the damaged bytes, and the rest of the clip decodes normally.
The trade is that ProRes is a rendered format. It carries the look, not the sensor data, so recovering it returns a finished picture rather than a gradeable one. Where ARRIRAW or BRAW originals exist alongside ProRes dailies, the RAW comes first and the ProRes is a convenience copy.
Where the container itself is damaged — a .mov whose index is missing or malformed — the fix is a container rebuild rather than data recovery, using the same procedures as any MP4-family file, documented in repairing corrupted video files. A large file that will not open is usually complete data wrapped around a broken index, which is a repairable condition rather than a loss.
The Decision Table: What Each Failure Costs, by Format
| Failure | Blackmagic RAW | R3D | ARRIRAW | ProRes |
|---|---|---|---|---|
| Clip deleted, card not reused | Recoverable in full | Recoverable in full | Recoverable in full if the folder and sidecar are intact | Recoverable in full |
| Card quick-formatted in camera | Recoverable in full | Recoverable in full | Recoverable in full | Recoverable in full |
| Recording interrupted, no final index | Recoverable: rebuild the frame index | Recoverable up to the last completed segment | Not applicable: no index exists | Recoverable: rebuild the container index |
| Damaged sectors over a range | Partial: the failing ranges are lost, the rest decodes | Partial: bounded by the affected segment | Partial: only the frame files on damaged sectors are lost | Partial: a short run of frames around the damage |
| Card overwritten and reused | Not recoverable | Not recoverable | Not recoverable | Not recoverable |
| Physically destroyed media or failed controller | Specialist laboratory, no software route | Specialist laboratory, no software route | Specialist laboratory, no software route | Specialist laboratory, no software route |
If you are on Windows and the media is still detected by a computer, a purpose-built recovery tool such as XRecovery (xappset.com) can scan SD, microSD, and other memory cards for deleted or formatted photos and videos. As with any recovery tool, stop writing to the card first and always save recovered files to a different drive. For production media the recovery workflow matches any other card, with one addition: a recovered file must be verified before it enters the pipeline, because a frame range that decodes is not automatically a frame range that is correct. Professional media and readers have their own notes, collected in recovering from professional cards.
Frequently Asked Questions
Can BRAW files be recovered after the card was formatted?
Usually yes, if the card has not been recorded to since the format. A camera format rewrites the file system’s structures and leaves the recorded data in place until new recordings claim those blocks. BRAW’s checksum data then tells you which recovered frames are intact, so you know exactly what you hold before the grade starts.
Why can’t a general video repair tool fix a damaged R3D?
Because the compressed stream is proprietary and wavelet-based. Consumer repair utilities can rebuild containers around readable codec streams, but they cannot reconstruct REDCODE from first principles. The correct tools are RED’s own; where the media itself has failed, the route is a vendor or laboratory service.
Is ARRIRAW harder to recover than BRAW?
It depends on the failure. A missing frame file is a permanent gap at a known frame number, which no tool can fill. But ARRIRAW has no container index to lose, so the failure mode that ruins most consumer video — thousands of intact frames with a broken index — cannot occur.
What should be copied first from a failing cinema card?
Small files. Sidecars, LUTs, XML metadata, and look files are tiny and carry the context needed to interpret the footage later. If the card dies mid-copy, an intact RAW frame with no color transform is worth less than the same frame with its metadata alongside it.
