Why does the Sony FX6 (ILME-FX6V / ILME-FX6T) create an unplayable .RSV file — and how do we rescue it?
The Sony FX6 (internal Sony model designation ILME-FX6V / ILME-FX6T, Cinema Line Vollformat Camcorder) records high-bitrate XAVC-I (Intra), XAVC-L (Long GOP), XAVC S / HS streams onto Dual CFexpress Typ A / SDXC UHS-II. Because of its specific hardware design and 4-Kanal 24-Bit 48 kHz LPCM audio pipeline, interrupted recordings on the Sony FX6 leave behind model-specific .RSV containers in /PRIVATE/M4ROOT/CLIP/.
What happened technically inside your Sony FX6?
While recording XAVC-I (Intra), XAVC-L (Long GOP), XAVC S / HS, the BIONZ XR processor of the Sony FX6 continuously writes video GOP chunks, 4-Kanal 24-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.
