Why does the Sony Alpha 1 (A1 / A1 II) (ILCE-1 / ILCE-1M2) create an unplayable .RSV file — and how do we rescue it?
The Sony Alpha 1 (A1 / A1 II) (internal Sony model designation ILCE-1 / ILCE-1M2, Alpha Flaggschiff (8K 30p & 4K 120p)) records high-bitrate XAVC HS 8K (4:2:0 / 4:2:2 10-Bit), 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 1 (A1 / A1 II) leave behind model-specific .RSV containers in /PRIVATE/M4ROOT/CLIP/.
What happened technically inside your Sony Alpha 1 (A1 / A1 II)?
While recording XAVC HS 8K (4:2:0 / 4:2:2 10-Bit), XAVC S-I 4K, XAVC S, the BIONZ XR processor of the Sony Alpha 1 (A1 / A1 II) 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.
