relay-recorded MP4: find after an import failure
Where are clips split across two card slots after a failed import?
Short answer
Often the second card's part was never imported: relay recordings span two cards, and an ingest that copies only one card misses the continuation. Check the destination for both parts, then import from the other card. Scan either card read-only only if the files are missing on the card itself.
The situation
clips split across two card slots is incomplete at the destination and no longer appears reliably on the source.
Check the destination for both halves of the take before you search the card. An ingest that only saw one card copies the part in that slot and stops there; the continuation was never lost, it simply never travelled, and it is still sitting on the second card.
01 / Diagnose
Work out what actually disappeared
Relay takes are numbered consecutively but spread across two media, and many ingest routines treat one card as a complete shoot day. Whoever imported the first card ends up with a take that stops mid-sentence, while the remainder waits in the other slot. Import logs rarely flag this, because nothing failed on the card that was read.
Move, rename, catalog and delete-after-import steps can fail at different moments and leave source and destination in different states. For relay-recorded MP4, this matters because a recording may continue on another card while numbering and metadata span both slots
Check the last known path, trash and backups without writing to the original device.
02 / Protect the source
Preserve the best recovery chance
- 1
List what the destination actually holds and compare it with the file numbers on both cards, not only the imported one.
- 2
Put the second card into a reader and copy its part of the take directly into the same project folder.
- 3
Search trash and catalogue for a half-copied file if the import broke off mid-transfer rather than skipping the card.
- 4
Join the two parts on a timeline and play across the join before either card is released for reuse.
Do not format or reuse a card because its clips look imported already: in a relay pair the numbering carries on, so a complete-looking sequence can still be missing its second half. Do not trim or transcode the imported part before the continuation is in place.
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.
File Recovery Hero reads exFAT, NTFS and FAT16/FAT32 media read-only and recovers files that have vanished from a card. While both parts are still on their cards, copying them again is faster and safer than any scan, and joining the parts remains an editing task.
04 / Verify
Check the recovered content, not just its name
The import is complete when both file numbers exist at the destination with the same sizes as on the cards and the joined duration matches the take. Play the transition: sound and picture should carry on without a gap, because the camera switched slots without stopping.
Keep the source until two verified copies exist. One working preview is not enough.

FAQ
Questions about this recovery case
Can dual-slot exFAT camera media be recovered in this situation?+
Check the destination for both halves of the take before you search the card. An ingest that only saw one card copies the part in that slot and stops there; the continuation was never lost, it simply never travelled, and it is still sitting on the second card. The result still depends on what remains readable on the source.
What should I avoid before scanning?+
Do not format or reuse a card because its clips look imported already: in a relay pair the numbering carries on, so a complete-looking sequence can still be missing its second half.
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?+
The import is complete when both file numbers exist at the destination with the same sizes as on the cards and the joined duration matches the take.
