Deleted Your Source Footage? Here's How to Get It Back

Recovering deleted source footage is often possible because deletion only removes the file index entry — the actual video data remains on the SD card or drive until new recording overwrites it. Source footage means the original camera files (MXF, MP4, MOV, XAVC-S, CRM) before any transcoding or proxy generation, and these files can often be recovered from SD cards and camera drives if you stop recording immediately and use the right tool. This guide covers every major camera brand's folder structure, chaptered file reassembly, and sidecar recovery so you retrieve complete, usable clips — not just fragments.

Part 1. Source Footage vs. Proxy — What You Are Actually Recovering

Source footage is the raw file written directly to the camera's storage card during recording. It is distinct from proxy files, optimized media, or cache files that editing software generates automatically.

Proxies and optimized media can be regenerated from source footage. Source footage itself cannot be regenerated — it is the only copy that matters.

💡 Tip: If your editing software shows "media offline" after a card format, the proxies on your workstation still exist. Recover the source footage from the card and relink — do not re-transcode from the proxy.

Part 2. Camera Folder Structures You Need to Know

Every camera brand writes footage to a specific folder hierarchy on the card. Recovery software that understands these structures can locate and reconstruct files even when the file allocation table is damaged or wiped.

💡 Tip: Before running any recovery scan, note which folder path your camera uses. Filter the scan results by that path to avoid sifting through thousands of unrelated files.

Recovery tools that only scan for generic MP4 or MOV headers may locate the video container but miss the associated metadata files that make clips properly playable in your NLE.

Part 3. Recovering GoPro Chaptered Footage

GoPro cameras split recordings longer than approximately 4 GB into sequential chapter files. A single 30-minute clip may become five or six separate files, each linked by a filename convention.

GoPro chapter naming follows this pattern:

• GH prefix — HEVC (H.265) recordings, HERO 9 and later
• GX prefix — AVC (H.264) recordings, HERO 9 and later
• GP prefix — older HERO models (HERO 7 and earlier)

The first chapter is GH010001.MP4, the second is GH020001.MP4, the third GH030001.MP4, and so on. The number in position 3–4 is the chapter counter; position 5–8 is the clip number.

⚠️ Important: If you recover GoPro files but rename them before confirming the chapter sequence, your NLE may treat them as separate clips and refuse to merge them. Preserve the original filenames exactly as recovered.

🗣️ r/videography user: "I recovered GoPro footage after a card wipe, but the recovery tool pulled back the chapters out of order. I had to sort them manually by filename prefix to get the correct sequence before importing into Premiere."

Each GoPro chapter also has companion files: an LRV (low-resolution video, used for preview) and a THM (thumbnail image). These share the same base filename and are stored in the same DCIM/100GOPRO/ folder. Recovering all three file types ensures your NLE can generate previews without re-scanning.

Part 4. Sidecar Files — XMP, SRT, LRV, and THM

Sidecar files store information that is linked to but separate from the main video container. Losing them means losing metadata, GPS tracks, color grades, and previews.

💡 Tip: When running a recovery scan, always enable scanning for ALL file types — not just .MP4 or .MOV. Filtering to video-only will skip every sidecar file, and you will lose GPS data and color metadata permanently.

🗣️ r/editors user: "After recovering Sony XAVC-S clips, the XML sidecar files were missing. The clips played fine, but Sony Catalyst Browse could not read the embedded metadata, so proxy generation had to be redone from scratch."

DJI SRT files are especially valuable for drone operators — they contain frame-by-frame GPS coordinates, altitude, gimbal angle, and camera settings. These files are typically small (under 1 MB) and are among the easiest to recover successfully since their data footprint is minimal.

Part 5. Step-by-Step Source Footage Recovery

Before you begin: Stop all recording on the card immediately. Do not save any new files to it. Every new write risks overwriting deleted footage.

Step 1 — Eject the card safely and connect to your computer. Use a dedicated card reader rather than the camera's USB connection. Direct camera USB connections sometimes auto-import or cache files to the card in the background.

Step 2 — Do not format the card if prompted. Operating systems may display a "card needs to be formatted" dialog when the file system is damaged. Decline this prompt and proceed to recovery software first.

Step 3 — Run a deep scan with a tool that supports your camera's format. Generic file carvers locate MP4 containers but may miss MXF wrappers, CRM files, or BRAW containers. Use a tool with camera-specific algorithms when possible.

Step 4 — Filter scan results by the camera's folder path. Navigate to the folder structure listed in the table in Part 2. This narrows results and surfaces properly structured files over fragmented partials.

Step 5 — Select all file types, including sidecars. Enable .xmp, .srt, .lrv, .thm, .xml, and .cif alongside video extensions.

Step 6 — Recover to a different drive — never to the source card. Saving recovered files back to the same card risks overwriting remaining deleted data. Use an external drive or your workstation's internal SSD.

Step 7 — Verify filenames and chapter sequences before importing. Check GoPro chapter prefixes (GH/GX/GP) and confirm clip numbers are sequential. Confirm DJI SRT filenames match their MP4 counterparts before importing to your NLE.

Part 6. Why Vendor-Specific Algorithms Matter

Generic recovery software works by scanning raw disk sectors for known file headers — for example, the ftyp box in an MP4 container. This approach works for simple, unfragmented recordings on healthy cards.

Camera-specific algorithms go further. They understand the proprietary container wrappers (MXF, CRM, BRAW), the embedded index files that link chapters together, and the folder hierarchy that the camera's firmware expects. When a card's FAT32 or exFAT allocation table is corrupted, these algorithms can reconstruct file boundaries from internal container markers rather than relying on the damaged index.

Sony XAVC-S files, for example, embed a clip metadata XML at a fixed offset within the container. A vendor-aware scanner reads that offset to determine clip length and frame rate even when the directory entry is gone. Canon CRM files use a similar embedded index structure.

Part 7. Recover Your Source Footage with Ritridata

Ritridata includes vendor-specific SD card recovery algorithms for Canon, Nikon, Sony, and DJI cameras, along with fragment reassembly for cards where the file allocation table is corrupted or wiped. It supports Windows and Mac and covers SD, microSD, CFexpress, and USB-connected storage.

Step 1 — Select the camera SD card or drive.

Open Ritridata and choose the card or drive where your source footage was stored. Ritridata detects SD cards, USB drives, and internal/external hard drives.

Step 2 — Run a safe scan.

Start the scan. Ritridata performs a non-destructive read of the storage device — no data is written to the card during this process. The deep scan mode activates vendor-specific algorithms for camera formats.

Step 3 — Preview and recover to a different drive.

Browse the scan results, preview recoverable clips, and select all associated sidecar files. Save the recovered files to a separate drive — not back to the source card.

FAQ

Can I recover source footage after formatting an SD card? In many cases, yes. A quick format rewrites the file allocation table but does not immediately erase the underlying video data. Stop using the card immediately and run a deep scan — the longer you wait, the higher the chance of overwrite.

What is the difference between source footage and proxy files? Source footage is the original file the camera recorded to the card. Proxy files are lower-resolution copies generated by your editing software for performance. Proxies can be regenerated; source footage cannot.

Can I recover GoPro chaptered files after accidental deletion? Yes, though you need to recover all chapters — not just the first. Look for files sharing the same clip number (positions 5–8 in the filename) across multiple chapter prefixes (GH01, GH02, GH03, etc.).

Are DJI SRT files recoverable alongside MP4 footage? SRT files are typically small plain-text files and often survive card damage better than large video containers. A full scan that includes all file types will surface them alongside the corresponding MP4.

Does recovering source footage damage the original card? A read-only scan does not modify the card. Writing recovered files back to the same card would risk overwriting remaining deleted data, so always recover to a separate drive.

Can I recover Sony XAVC-S or Canon CRM files with standard recovery tools? Standard tools may locate the MP4 or MXF container but miss the linked metadata XML or CIF file. Vendor-specific algorithms that understand camera folder structures and embedded index offsets give more complete results.

Should I stop recording immediately after accidental deletion? Yes — this is the single most important action. Every new frame recorded to the card risks overwriting deleted footage. Eject the card, connect it to a computer via a card reader, and run recovery software before doing anything else.
