Why does the Sony Alpha 7C II & A7CR (ILCE-7CM2 / ILCE-7CR) create an unplayable .RSV file — and how do we rescue it?
The Sony Alpha 7C II & A7CR (internal Sony model designation ILCE-7CM2 / ILCE-7CR, Kompakte Vollformat-Serie) records high-bitrate XAVC HS 4K, XAVC S 4K, XAVC S-I 4K streams onto 1× SDXC UHS-II. Because of its specific hardware design and 2-Kanal 16-Bit 48 kHz LPCM audio pipeline, interrupted recordings on the Sony Alpha 7C II & A7CR leave behind model-specific .RSV containers in /PRIVATE/M4ROOT/CLIP/.
What happened technically inside your Sony Alpha 7C II & A7CR?
While recording XAVC HS 4K, XAVC S 4K, XAVC S-I 4K, the BIONZ XR processor of the Sony Alpha 7C II & A7CR continuously writes video GOP chunks, 2-Kanal 16-Bit 48 kHz LPCM 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.
