Recover video from a V90 SDXC card
Can deleted high-bitrate video be recovered from V90 media?
Short answer
Yes, often, but V90 speed offers deleted clips no protection: large high-bitrate files can still be fragmented or overwritten by the next take. Stop recording, scan the card read-only for MP4, MOV or MXF, and validate each recovered stream over its full duration before relying on it.
The situation
High-bitrate MP4, MOV, or MXF clips were deleted from fast camera media.
A V90 rating describes a minimum sustained write rate and nothing else. It offers deleted clips no protection at all, and in practice it makes the card attractive for the highest bitrates, so the files at risk here are the largest and the most easily fragmented ones on set.
01 / Diagnose
Work out what actually disappeared
V90 cards end up in bodies recording 4K or 6K footage where a single minute occupies several gigabytes. Deleting such a clip frees a long run of clusters that the next take fills immediately. If the card was formatted or clips were removed across several sessions, the free areas are scattered, and a new recording can land in the middle of an older take.
The speed class does not protect deleted extents; large files can still be fragmented or overwritten.
Check the last known path, trash and backups without writing to the original device.
02 / Protect the source
Preserve the best recovery chance
- 1
Take the V90 card out of the camera at once and shoot the rest of the session on other media.
- 2
Note the recording mode, the codec and the approximate length of each missing clip, since that is what the results will be measured against.
- 3
Read the card in a reader that can sustain the transfer rate and scan the exFAT volume read-only for MP4, MOV or MXF.
- 4
Export to a drive with several times the card capacity free, then review each clip in full before the card returns to service.
Do not use the card for even one more take, and do not trust a quick preview of the opening frames. Copying results back to the source, or formatting the card to clear a mount warning, removes data that a second pass could still reach.
03 / Choose the method
Match the tool to the source
For stable, readable exFAT, NTFS and FAT16/FAT32 or uncompressed IMG, DD, RAW and BIN images.
Unconfirmed exports are marked .UNVERIFIED.
Fragmented takes can come back as usable fragments rather than whole clips, and File Recovery Hero rebuilds no index and repairs no container. Cards that fail physically, encrypted volumes and file systems beyond exFAT, NTFS and FAT16/FAT32 stay outside its reach.
04 / Verify
Check the recovered content, not just its name
Play each recovered clip backwards as well as forwards and compare its runtime with what was shot. A file whose size falls far below the bitrate multiplied by the duration lost part of its stream, and frozen images over running audio show the same problem in the picture.
Keep the source until two verified copies exist. One working preview is not enough.

FAQ
Questions about this recovery case
Can V90 exFAT SDXC card be recovered in this situation?+
A V90 rating describes a minimum sustained write rate and nothing else. It offers deleted clips no protection at all, and in practice it makes the card attractive for the highest bitrates, so the files at risk here are the largest and the most easily fragmented ones on set. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
Do not use the card for even one more take, and do not trust a quick preview of the opening frames.
Does scanning write to my memory card?+
Your memory card is only read. Nothing is saved to it.
How do I know whether the result is complete?+
Play each recovered clip backwards as well as forwards and compare its runtime with what was shot.
