Proxy Clips (Simultaneous Recording)
In CAMERA mode, while recording a primary clip on a CFexpress card, you can simultaneously record the same
scene as a proxy clip (XF-AVC format) on the SD card. Because proxy clips have smaller files, they are suitable

• Proxy clips will be recorded on the SD card simultaneously with the primary clips recorded on the CFexpress
card.
NOTES NOTES
• If the recording of the primary clip stops during simultaneous recording, recording of the proxy clip will stop as
well.
• Simultaneous recording of proxy clips is not available when the main recording format is set to XF-AVC and
slow & fast motion recording is activated.
• If there is no CFexpress card inserted in the camera, only the proxy clip will be recorded.
• SDHC cards are formatted using the FAT32 file system so, when recording proxy clips, the video (stream) file in
the clip will be split approximately every 4 GB. Playback with the camera will be seamless.
SDXC cards use the exFAT file system so the stream file in the clip will not be split.
