Why does the Sony Alpha 9 III (A9M3) (ILCE-9M3) create an unplayable .RSV file — and how do we rescue it?
The Sony Alpha 9 III (A9M3) (internal Sony model designation ILCE-9M3, Global Shutter Vollformat) records high-bitrate XAVC HS 4K 120p (ohne Crop), XAVC S-I 4K, XAVC S streams onto Dual CFexpress Typ A / SDXC UHS-II. Because of its specific hardware design and 2-Kanal 16-Bit / 4-Kanal 24-Bit LPCM audio pipeline, interrupted recordings on the Sony Alpha 9 III (A9M3) leave behind model-specific .RSV containers in /PRIVATE/M4ROOT/CLIP/.
What happened technically inside your Sony Alpha 9 III (A9M3)?
While recording XAVC HS 4K 120p (ohne Crop), XAVC S-I 4K, XAVC S, the BIONZ XR processor of the Sony Alpha 9 III (A9M3) continuously writes video GOP chunks, 2-Kanal 16-Bit / 4-Kanal 24-Bit 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.
