Proxy clips (simultaneous recording) on the EOS C500 Mark II

In Camera mode, while recording a RAW 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 for offline editing.

  1. Set the main recording format to [RAW].
  2. Select MENU > [ Recording/Media Setup] > [Sub Rec Format] > [XF-AVC (SD Card)].
    • The  icon will appear in green at the top left of the screen.
  3. Press the REC button to start and stop recording.
    • Proxy clips will be recorded on the SD card simultaneously with the primary clips recorded on the CFexpress card.

  • If the recording of the primary clip stops during simultaneous recording, recording of the proxy clip will stop as well.
  • 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.
