Why does the Sony FX30 (ILME-FX30 / ILME-FX30B) create an unplayable .RSV file — and how do we rescue it?
The Sony FX30 (internal Sony model designation ILME-FX30 / ILME-FX30B, Cinema Line APS-C / Super 35) records high-bitrate XAVC S-I 4K DCI/UHD, XAVC HS 4K (6K Oversampling), XAVC S HD streams onto Dual CFexpress Typ A / SDXC UHS-II. Because of its specific hardware design and 2-Kanal 16-Bit oder 4-Kanal 24-Bit 48 kHz LPCM audio pipeline, interrupted recordings on the Sony FX30 leave behind model-specific .RSV containers in /PRIVATE/M4ROOT/CLIP/.
What happened technically inside your Sony FX30?
While recording XAVC S-I 4K DCI/UHD, XAVC HS 4K (6K Oversampling), XAVC S HD, the BIONZ XR processor of the Sony FX30 continuously writes video GOP chunks, 2-Kanal 16-Bit oder 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.
