Why does the Sony FX3 (ILME-FX3 / ILME-FX3A) create an unplayable .RSV file — and how do we rescue it?
The Sony FX3 (internal Sony model designation ILME-FX3 / ILME-FX3A, Cinema Line Vollformat) records high-bitrate XAVC S-I 4K (All-Intra 600 Mbit/s), XAVC HS 4K (HEVC 10-Bit 4:2:2), XAVC S streams onto Dual CFexpress Typ A / SDXC UHS-II (Slot A & B). Because of its specific hardware design and 2-Kanal oder 4-Kanal 24-Bit 48 kHz LPCM (über XLR-H1 Handgriff) audio pipeline, interrupted recordings on the Sony FX3 leave behind model-specific .RSV containers in /PRIVATE/M4ROOT/CLIP/.
What happened technically inside your Sony FX3?
While recording XAVC S-I 4K (All-Intra 600 Mbit/s), XAVC HS 4K (HEVC 10-Bit 4:2:2), XAVC S, the BIONZ XR processor of the Sony FX3 continuously writes video GOP chunks, 2-Kanal oder 4-Kanal 24-Bit 48 kHz LPCM (über XLR-H1 Handgriff) 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.
