Why ProRes RAW footage goes "corrupt" in DaVinci Resolve
Short answer: ProRes RAW files use Apple's .mov container. When DaVinci Resolve (or any NLE) crashes or a power cut interrupts a render or export, the .mov file's moov atom — the container index that tells media players where each video frame, audio track, and timecode sits — is never written. The result: a file that opens to 0 seconds, or refuses to load entirely. The raw video data is physically present on the drive; only the index is missing. This is a software repair, not a physical recovery, in most cases.
How to recover corrupt ProRes RAW footage
Step 1: Try DaVinci Resolve's native rebuild first
If DaVinci Resolve crashed mid-export, right-click the corrupt clip in the Media Pool and look for "Reconstruct" or "Relink Media." Resolve sometimes detects the moov atom issue automatically and offers a cache-based rebuild. Also check DaVinci's proxy cache — if you generated proxies before the crash, the proxy versions of every clip survive and are immediately editable. Open Preferences → Media Storage and navigate to the cache folder. Proxy files are typically 50–90% smaller than ProRes RAW originals but fully playable at proxy resolution. For the Final Cut Pro library recovery guide (same moov atom issue, same fix), the process is near-identical for Apple-codec files.
Step 2: Use ffmpeg to rebuild the moov atom
Download ffmpeg (free, open-source) on a healthy machine. Run: ffmpeg -i corrupt_file.mov -c copy recovered_file.mov. If the file has a complete ftyp header but missing moov atom, ffmpeg will read the raw codec data and re-wrap it with a valid moov atom. This works on ProRes, ProRes RAW, and ProRes HQ files. If ffmpeg reports "moov atom not found" and exits with zero output, the container header itself is damaged — try ffmpeg -r 24 -f rawvideo -pix_fmt yuv422p10le -s 3840x2160 -i corrupt_file.mov recovered.mov with the correct resolution and frame rate for your footage. This is a brute-force re-wrap that strips the container and rebuilds from raw bitstream.
Step 3: Treasured or similar for complex corruption
Treasured (macOS, by Coherent Bits) is purpose-built for .mov and .mp4 container repair. It reconstructs the moov atom by analysing the raw NALU (Network Abstraction Layer Unit) headers embedded in the video data itself. This approach recovers files that ffmpeg cannot. Treasured charges per-file (around ₹1,500–₹2,500 equivalent per file), so it is worth using only when the footage is irreplaceable — wedding shoots, commercial productions, sports captures. For the related MP4 video carving and recovery guide, that post covers file-carving techniques for when even the container start marker is missing.
Step 4: The India context — power cuts mid-render
India's power infrastructure makes video editors particularly vulnerable during long renders. A 4K ProRes RAW export that takes 45 minutes is a 45-minute window where a power cut produces exactly the unfinished moov atom problem described above. The prevention is simple: connect the editing workstation or laptop to a UPS (uninterruptible power supply) sized for at least 10–15 minutes of runtime — enough to save the project and shut down cleanly. A ₹4,000–₹8,000 UPS is cheap compared to even one corrupt footage recovery job. Also enable DaVinci Resolve's Project Backup (Preferences → System → Backup) with a 10-minute interval — this creates dated .drp backups even if the export is interrupted.
When to call a data recovery professional
When DIY ends
Escalate if: ffmpeg and Treasured both fail; the drive itself shows SMART errors or slow read speeds; the footage is from a CFexpress or ProRes RAW capture card that has a filesystem issue; or the drive was physically dropped while recording.
Typical recovery cost in India
Logical video file repair (.mov container reconstruction): ₹2,500–₹6,000. Physical SSD recovery for a video editing drive: ₹8,000–₹25,000. Raid-based video storage recovery: covered in the RAID data recovery guide for India.
A note from the LRW Engineer Team
Never edit directly from camera media cards — SD, CFexpress, or SXS. Always offload to a primary NVMe, verify the transfer (use Hedge or Shot Put Pro for checksum verification), then start editing. A corrupt source card mid-edit is a full-clip loss that no repair tool can fix if the card's controller has failed. For Indian video production teams, a ₹20,000 RAID 1 NAS as primary storage is the single best investment for footage safety.
