Fix Sony .rsv files

A .rsv is an unfinished recording a Sony camera leaves behind when capture is interrupted: a dead battery, a card pulled mid-record, or a crash. Your video is usually still inside; the file just lacks the MP4 container a normal player needs.

You can’t open a .rsv directly in a normal player, because it’s missing the MP4 container. rsv.repair rebuilds that container so the file opens like any other video: drop the .rsv in, click Fix video, then open the resulting .mp4 anywhere.

A .rsv holds the video data but not the wrapper a player needs to read it, so it won’t play back as-is. Once rsv.repair rebuilds the wrapper, the footage plays back normally in any player or editor.

Yes, completely free, with no account, watermark, or upload, and a donation never unlocks anything. It’s built and run by one developer, Ben, so if it saved your footage and you’d like to give back, that’s welcome but never expected. Posting about the site helps just as much: a quick mention to other Sony shooters means the next person with a dead .rsv finds the fix here instead of losing the shoot. Buy Ben a pizza.

No. The repair runs entirely on your own computer, in the browser, so your .rsv and the recovered video stay on your device. We do collect anonymous, aggregate stats on how repairs go (the outcome, timing, and details like codec and camera model, never your footage, file name, IP address, or camera serial number). And if a file can’t be recovered, you can choose to upload a small sample to help us add support, but only if you click the upload button. Read the full privacy details.

So far we’ve recovered .rsv files from the Sony FX3, FX30, FX6, FX9, FR7, a6700, a7C II, a7S III, a7 V, a7R V, and the older a7R III, plus X-OCN recordings from the VENICE line and BURANO. If your model isn’t on the list, it’s still worth a try: most Sony bodies that leave a .rsv behind work, and you find out in seconds. The matching model codes are ILME-FX3 / FX3A, ILME-FX30, ILME-FX6V, PXW-FX9V, ILME-FR7, ILCE-6700, ILCE-7CM2, ILCE-7SM3, ILCE-7M5, ILCE-7RM5, ILCE-7RM3, MPC-3610 / 3626 / 3628, and MPC-2610.

Yes. An interrupted X-OCN take leaves the same .rsv scheme, and rsv.repair rebuilds it into a finalized .mxf that Resolve, Premiere, Catalyst, and RAW Viewer open like any camera original. The essence is copied untouched, no reference clip is needed, and everything runs in your browser as usual. Two differences from the MP4 flow: the output is an .mxf rather than an .mp4, and there is no playback preview beforehand, since no browser can decode X-OCN. The clip details still show before you commit.

Open rsv.repair in Chrome or another Chromium-based browser like Edge or Brave on any desktop computer, drop in your .rsv file, and click Fix video. The tool rebuilds a standard .mp4 from the footage and saves it to your computer. No other software needed.

A few files need a short reference clip from the same camera, and some can’t be rebuilt at all. If a repair fails, the tool explains why on screen and you can reach out to support.
