Simultaneous Recording Of Proxy Clips - Canon EOS C300 Mark II Instruction Manual

Simultaneous Recording of Proxy Clips

In addition to the primary clip recorded on a CFast card, you can simultaneously record the same scene as a
proxy clip on an SD card. Compared to 4K clips, proxy clips have a relatively more manageable video
configuration of 2K with YCbCr 4:2:0, 8-bit color sampling and a bit rate of 24 Mbps or 35 Mbps*, which makes
them very convenient for offline editing. Additionally, by specifying a LUT, you can obtain proxy clips with different
color space/gamma characteristics from those of the primary clips.
* Determined automatically depending on the video configuration of the primary clip.

• A proxy clip will be recorded on the SD card at the same time the primary clip is recorded on the CFast card.
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.
• During interval recording, frame recording or slow & fast motion recording, proxy clips will not be recorded.
• During relay recording, if the camera switches from recording on one CFast card to the other, the recording of
the proxy clip will be interrupted as well and continue as a separate proxy clip.
• 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.
