Recording Video

IMPORTANT

• Observe the following precautions while the CF

2

 or CF

3

 access indicator is illuminated in red. Failure to do 

so may result in permanent data loss.
- Do not open the CF card slot cover of the CF card slot being accessed and remove the CF card.
- Do not disconnect the power source or turn off the camera.

• Be sure to save your recordings regularly (

A

153), especially after making important recordings. Canon shall 

not be liable for any loss or corruption of data.

NOTES

• By default, [

 4K/2K/MXF Setup] 

>

 [Rec Command] is set to [On]. With this function, when you connect the 

camera to another device using the 3G-SDI terminals (in 4K and 2K modes) or HD/SD SDI terminal (in MXF 
mode), if you start or stop recording with the camera, the other device will also start or stop recording.

Locking the Controls in Recording Mode

Once in 

 mode, you can set the 

Q

 switch to 

C

 (key lock) 

to lock all the physical controls (buttons and switches) on the camera*, 
save for the START/STOP button. With the [

w

 Other Functions] 

>

[Custom Function] 

>

 [

C

 START/STOP] setting, you can even choose 

to lock all buttons, including the START/STOP button. In such case, you 
can use Wi-Fi Remote to operate the camera. This is useful in 
preventing settings from being changed due to inadvertently pressing 
one of the buttons. Return the 

Q

 switch to the CAMERA position 

to reactivate the controls. 

* The Wi-Fi Remote application also has a key lock function that is limited only to the 

controls on the application’s screens (you will still be able to use the controls on the 
camera). Press [

D

] to lock the application’s controls; press [

C

] to reactivate them.

About Clips

When the camera records an MXF clip, it also assigns a 6-character clip name consisting of a 2-character 
prefix (letters or numerals) and 4 numerals (for example, “AA0001”). The last 4 numbers serve as a running 
counter that increases every time a clip is recorded. You can set the initial clip name in advance using the [

4K/2K/MXF Setup] 

>

 [Clip Name] 

>

 [Title Prefix] and [Number Setting] settings. You cannot change the clip 

name after the clip is recorded.

In 4K and 2K modes, the clip name is included with the video signal that is output from the 3G-SDI terminals. 
If you use the software 

Cinema RAW Development

 to develop RAW clips recorded with an external recorder 

and export them, MXF clips recorded on a CF card and the exported files can be given similar names to make 
post-production more efficient. In the following cases, the clip name is not sent to the external recorder.

• During MXF mode.

• When the CF card in the camera cannot be recorded on, does not have enough available space or has an access error.

• During 4K and 2K modes, when using the interval recording, frame recording or slow & fast motion 

recording modes.

NOTES

• When recording MXF clips, the following apply.

- If you are recording with two CF cards and the CF card you are using becomes full while recording, the 

clip will continue uninterrupted on the other CF card when relay recording (

A

46) is activated. In such 

case, the recording will be recorded as separate clips.

- If you record using the custom picture and metadata settings, those settings will be recorded with the 

clip. For more details, refer to 

Custom Picture Settings

 (

A

114) and 

Using Metadata

 (

A

97).

- The video (stream) file in a clip will be split approximately every 2 GB for clips with a long recording time 

(approximately every 1 GB during slow motion recording). Even in such case, playback will be continuous.
