Why does the Sony Alpha 7S III (A7SM3) (ILCE-7SM3) create an unplayable .RSV file — and how do we rescue it?
The Sony Alpha 7S III (A7SM3) (internal Sony model designation ILCE-7SM3, Alpha Vollformat Low-Light & High-Speed) records high-bitrate XAVC HS 4K 120p, XAVC S-I 4K, XAVC S 4K streams onto Dual CFexpress Typ A / SDXC UHS-II. Because of its specific hardware design and 2-Kanal 16-Bit oder 4-Kanal 24-Bit LPCM (mit XLR-K3M) audio pipeline, interrupted recordings on the Sony Alpha 7S III (A7SM3) leave behind model-specific .RSV containers in /PRIVATE/M4ROOT/CLIP/.
What happened technically inside your Sony Alpha 7S III (A7SM3)?
While recording XAVC HS 4K 120p, XAVC S-I 4K, XAVC S 4K, the BIONZ XR processor of the Sony Alpha 7S III (A7SM3) continuously writes video GOP chunks, 2-Kanal 16-Bit oder 4-Kanal 24-Bit LPCM (mit XLR-K3M) audio blocks, and real-time gyro metadata (RTMD) into a temporary .RSV file. Only when you press REC Stop does the camera write the closing MP4 index ("moov" atom). If power or card writing fails mid-take, DaVinci Resolve, Premiere Pro, Final Cut Pro, and VLC cannot open the .RSV file.
