Sony FX30 .RSV file recovery

Your FX30 stopped mid-recording and left a .RSV file. Here’s how to get the clip back.

The FX30 (ILME-FX30) records XAVC S, XAVC HS and XAVC S-I, 8- or 10-bit, with LPCM sound. While it records, it writes the clip to a temporary .RSV file in PRIVATE/M4ROOT/CLIP/ and turns it into an .MP4 when you press stop. If the battery dies, the card fills up or the camera overheats first, the .RSV is left behind and won’t open.

The FX30 writes the same kind of .RSV as the FX3, so it is rebuilt the same way.

How to recover it

  1. Stop using the card and copy everything on it to your computer.
  2. Open rsvrescue.com and drop the .RSV from the copy. It’s read in your browser; nothing is uploaded.
  3. Watch the free 15-second preview with sound.
  4. Pay once for the file and save the repaired .MOV, which opens in Premiere Pro, Final Cut Pro, DaVinci Resolve, QuickTime and VLC.

RSV Rescue reads the FX30’s own settings from the .RSV itself, so you don’t need a reference clip, and it handles clips where you changed settings partway through. More detail: how to recover a Sony .RSV file.
