AtomFix recovers corrupted & truncated MP4 and MOV files in seconds — fully offline, no cloud upload, no subscription.
AtomFix is purpose-built to restore truncated or corrupted video streams when recording was unexpectedly interrupted.
Sony and other modern cameras generate temporary .RSV files when a recording stops prematurely. AtomFix restores and converts them into playable MP4s.
The file exists on your drive with full megabytes or gigabytes, but media players report a playback error, black screen, or corrupted header.
Sudden battery exhaustion cuts off recording before the device can write the essential concluding index and metadata to disk.
Memory card was ejected, jarred loose, or pulled out while footage was still buffering, leaving the raw video data incomplete.
The native filming app, drone controller software, or third-party camera tool froze or crashed during an active shoot.
Abrupt power cutoffs on drones, vehicle dashcams, action cameras, or studio rigs before the video file could be properly saved.
MP4 and MOV files require a container atom called the moov atom to understand where each audio and video frame lives. When recording is interrupted, this atom is never finalized. AtomFix reconstructs this atom from scratch using a healthy reference clip from the same device.
Drag & drop (or browse) your corrupted MP4 or MOV file into the Broken File zone.
Add any healthy video from the same camera — it rebuilds the file structure.
Click Repair. AtomFix reconstructs your video and saves a playable file. Done.
No subscriptions, no upsells, no nonsense. Pay once — repair unlimited videos for life.

AtomFix supports MP4 and MOV files — the most common formats from cameras, drones, iPhones, and DSLRs. This covers GoPro, DJI, Apple ProRes, Sony, Panasonic, and most other modern cameras.
No. AtomFix is fully offline. After you install it, you never need an internet connection again. Your video files never leave your computer.
A reference file is any healthy (playable) video from the same camera. AtomFix uses it to understand the file structure, then rebuilds the broken file's header. It doesn't need to be the same scene — just the same camera.
Yes! This is AtomFix's primary use case. Videos interrupted by a dead battery, ejected SD card, or device crash are often missing their "moov atom" header. AtomFix rebuilds it from the reference file, making the video playable again.
