TL;DR:

To successfully restore MP4 files from an SD card, immediately stop using the card to prevent data overwriting, connect it to a computer via a stable card reader, and use a video recovery tool to scan and save the files to an entirely different drive.
    ● If the SD card displays a RAW status or prompts for formatting upon connection, cancel the prompt and avoid writing any data to protect the original file system.
    ● If a recovered MP4 file fails to play, attempt to recover another version of the same file with a different size or timestamp before resorting to a dedicated video repair tool.
    ● Ensure you recover all related MP4 segments and sidecar metadata files, as cameras frequently split long recordings into multiple files that need to be restored together.

MP4 files can often be restored from an SD card if the card is no longer used after deletion or formatting. The safest approach is to stop recording immediately, connect the card to a computer, scan the card with a video-capable recovery tool, and save recovered files to a different drive.

Use the steps below to restore MP4 files from SD card storage while minimizing the risk of overwriting deleted video data.

Step 1
Stop using the SD card at once. New recordings can overwrite deleted video data and reduce the chance to restore MP4 files from SD card storage.
Step 2
Connect the SD card or memory card to a computer with a stable card reader. If the card asks for formatting, cancel the prompt and avoid writing any data.
Step 3
Run an SD card video recovery scan with a tool that supports MP4 and memory card file systems such as FAT32 or exFAT. Use a deep scan if the quick scan finds incomplete results.
Step 4
Preview found video files if preview is available. Select the needed results and recover MP4 from memory card storage to a different location, such as an internal drive.
Step 5
Test the recovered MP4 files in a media player. If playback fails, try another recovered version with a different file size or timestamp first. If the recovered file is complete but still corrupted, use video repair after recovery.

Common Issues and Fixes

Recovered MP4 will not play — Likely cause: the file header is damaged, the recording is incomplete, or the video was only partially recovered. Fix: recover another version of the same file first, then use a video repair tool if the recovered MP4 still cannot play.
SD card is not detected — Likely cause: the card reader, adapter, USB port, or card contacts may be faulty. Fix: try another reader, another USB port, or gently clean the card contacts before scanning.
Recovery scan finds no videos — Likely cause: the card may have been overwritten, encrypted, or severely corrupted. Fix: run a deep scan and check whether the camera stored files under another extension or folder.
Card shows RAW or asks to format — Likely cause: the SD card file system is damaged. Fix: avoid formatting first and perform SD card video recovery before any repair attempt.
Recovered filenames are missing — Likely cause: file system records were lost after deletion or formatting. Fix: sort results by file type, size, and modified date to identify the correct MP4 clips.

Quick Tips

These tips can improve your chances of getting playable MP4 clips back.

Cameras sometimes split long recordings into multiple MP4 segments. Recover all related clips before checking playback.
A formatted SD card may still allow recovery if no new video was recorded after formatting.
Some action cameras save video metadata separately. Recover sidecar files as well if available.
Direct recovery from the camera is less reliable than recovery through a card reader.

💡Protip:

Before scanning the SD card, do not format it, record new videos, or save recovered MP4 files back to the same card. New writes can overwrite video data that may still be recoverable.
