Simultaneous Recording of Proxy Clips
Simultaneous Recording of Proxy Clips
In addition to the primary clip recorded in RAW on a CFast card, you can simultaneously record the same scene
as a proxy clip (in MP4 format) on an SD card. Because proxy clips are relatively smaller files, they are suitable for
110
offline editing.
Operating modes:
1 Set the main recording format to RAW (A 64).
2 Open the proxy recording [Sub Rec Format] submenu.
> [Æ ! Recording/Media Setup] > [Sub Rec Format]
3 If necessary, select the audio format (A 99).
4 Select [MP4 (SD Card)] and then press the joystick.
5 Press the REC button to start and stop recording.
• A proxy clip will be recorded on the SD card at the same time the primary clip is recorded on the CFast card.
Video and audio configuration of proxy clips
The recorded proxy clip has the following video and audio video configuration. The frame rate is the same as
that used for the primary clip.
Video: 2K (2048x1080), YCbCr 4:2:0, 8 bit; 35 Mbps bit rate
Audio: MPEG-4 AAC-LC, 16 bit, 48 kHz, 2 channels or Linear PCM, 16 bit, 48 kHz, 4 channels
IMPORTANT
• Observe the following precautions while an access indicator is illuminated in red. Failure to do so may result in
permanent data loss.
- Do not open the card slot cover of the card being accessed and do not remove the card.
- Do not disconnect the power source or turn off the camera.
NOTES
NOTES
• If the recording of the primary clip stops during simultaneous recording, recording of the proxy clip will stop as well.
• When an SD or SDHC card is used to record proxy clips, the video (stream) file in a proxy clip will be split
approximately every 4 GB for clips with long recording times. Still, playback on the camera will be continuous.
• During HDR output (A 143), the [LUT: BT.709] LUT (A 144) will be applied automatically to the proxy clip.
• If proxy clip recording is activated but no CFast card is inserted in the camera, the proxy clip will not be
recorded.
