Fix an NVR export that won't play (Lorex, Amcrest, Uniview & more).
NVR footage from Lorex, Amcrest, Uniview and similar systems that plays on the recorder but not your PC is usually a format issue — it needs re-packaging into a standard file. A cut-off backup gets rebuilt instead. Upload it and we'll fix what's fixable.

We couldn't recover this one.
The file is too damaged to rebuild, so there is nothing to preview and no charge.

Try a deep repair
The repair engine can try a longer pass on the file you already uploaded.
Machine-only processing; no human views files; nothing is sent to an outside AI.
Have another clip from the same device?
A healthy video recorded on the same device — ideally the same settings — gives the repair engine a template to rebuild from. It can unlock repairs that fail on their own.
Unrepaired files are kept encrypted for up to 30 days, then deleted.
FileFix can't fix that kind of file yet.
Right now we repair video, audio, document, and image files (MP4, MOV, M4V, MKV, AVI, TS, MTS, M2TS, MPG, MPEG, VOB, 3GP, WebM, FLV, M4A, WAV, MP3, AAC, FLAC, OGG, OPUS, AIFF, XLSX, DOCX, PPTX, ODT, ZIP, RAR, PDF, AI, HEIC, and HEIF). We're adding support for more formats over time.

Why NVR exports won't play on a computer
Network video recorders from Lorex, Amcrest, Uniview, and the many brands built on shared hardware all behave alike: they record efficient H.264/H.265 into their own container, tuned for playback on the recorder or in the vendor's app. Move a clip to a computer and standard players frequently can't read it — a black screen, audio-only, or an outright error on footage that's perfectly intact.
When that's the problem, it's a container or codec mismatch, not damage. Re-packaging the healthy stream into a standard MP4 — or converting a proprietary codec — makes it play in VLC and any normal player, without re-encoding or losing quality.
The second failure is a truncated export. You pulled a backup to a USB drive or over the network and the transfer was interrupted, or the disk filled up mid-write. The footage is partly there, but the file is missing its end and index, so nothing opens it until it's rebuilt.
FileFix handles both cases from the file you upload, and the free preview shows you the playable result before you pay. If your NVR is a Reolink, or the camera is Hikvision or Dahua, those pages cover the brand specifics; otherwise upload here. If the export is empty, we tell you plainly and there's no charge.
What we can and can't fix
We can usually fix
- The footage is healthy but won't play off-device because of the NVR's container/codec, or a backup was truncated mid-copy — we remux, convert, or rebuild it into a file that plays anywhere.
We can't fix
- The export is 0 bytes or captured no footage at all — there's nothing to re-package or rebuild. More on that →
How it works
-
Upload Drop a supported video file in. It uploads over an encrypted connection. The repair runs automatically — no person watches your file.
-
Free watermarked preview You see a free watermarked preview and exactly how much we recovered.
-
Pay & download If it's right, you pay from $12 USD once and download a clean, full-quality MP4.
About half of real-world corrupted files repair fully, and you always preview before paying.

Questions
Almost certainly. Lorex, Amcrest, Uniview and most others fail the same two ways — format mismatch or truncated export — so we work from the exported file rather than the brand. Upload it and the free check tells you what's going on.
The vendor app understands its own container and codec; standard players don't. Converting the clip to a normal MP4 lets it play everywhere, which the free preview demonstrates before you pay.
Where the stream can be re-packaged, there's zero quality loss — the original footage is copied as-is. Where a proprietary codec must be normalized, we optimize for a faithful, playable result and you see it before deciding.
