Sony a7R V .RSV file recovery

Your a7R V stopped mid-recording and left a .RSV file. Here’s how to get the clip back.

The a7R V (ILCE-7RM5) records XAVC S, XAVC HS and XAVC S-I, 8- or 10-bit, up to 8K 24p and 4K 60p, 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.

Long 8K takes generate heat and fill cards quickly, the two usual causes of an a7R V .RSV.

How to recover it

Stop using the card and copy everything on it to your computer.
Open rsvrescue.com and drop the .RSV from the copy. It’s read in your browser; nothing is uploaded.
Watch the free 15-second preview with sound.
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 a7R V’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.

a7R V tips to avoid losing a take

Battery: the a7R V uses the NP-FZ100. Start long takes on a full battery, swap between takes rather than during one, or use external power.
Back up as you shoot: the a7R V has two slots that each take CFexpress Type A or SD cards. Set Recording Mode to simultaneous recording (Simult. Rec) so every clip is written to both cards; if one take ends as a .RSV, the other card often has a complete copy.
Heat: Set Auto Power OFF Temp. to High for long takes, and avoid long 8K takes in direct sun.
Tip: 8K files are large; check the remaining recording time before a long take.
