Troubleshooting
Media is almost full
- During relay recording, the combined space available on CFexpress A and CFexpress B is low.
- During double slot recording, the space available on CFexpress A or CFexpress B (the fullest one) is low.
- During normal recording, the space available on CFexpress A or CFexpress B (the card being used for recording) is
220
low.
- The amount of available space on the SD card is low. Replace the card or delete recordings (A 145) to free some
space on the card.
Memory card is write-protected
- The LOCK switch on the SD card is set to prevent accidental erasure. Change the position of the LOCK switch.
No clips
- There are no clips of the selected video format on the selected card.
No photos
- There are no photos on the SD card.
Noise levels will rise on the image of the sub recording and on video outputs not in RAW.
- The main recording format is set to RAW and the gamma curve component of the [Gamma/Color Space] setting in the
custom picture file is set to an option other than [Canon Log 2] or [Canon Log 3]. Under such conditions, there may be
more noise on the recorded proxy clips (SD card) and on video output from the various terminals.
Number of clips already at maximum
- The card selected for recording already contains the maximum number of clips (999 clips). Replace the card or use the
CFexpress card in the other card slot.
- Because both CFexpress cards reached the maximum number of clips, double slot recording is not available.
Number of Shot Marks at maximum
- The shot mark could not be added because the clip already contains 100 shot marks.
Power Zoom Adapter Check the power supply.
- The power zoom adapter's remaining battery charge is low. Replace the power zoom adapter's batteries.
Power Zoom Adapter Temperature too high. Cannot perform task.
- The power zoom adapter cannot be operated because its temperature is too high. Stop using the power zoom adapter
and let it cool down before using it again.
Recorded at 24.00 Hz/50.00 Hz/59.94 Hz CFexpress A/CFexpress B/SD Card: Recommend checking the data and
initializing
- The card contains clips that were recorded using a system frequency different from the one currently used by the
camera. To record on this card, save your recordings and initialize the card with the camera (A 46). To play back the
XF-AVC clips recorded on the card, change the camera's system frequency (A 62) to match the recordings on the
recording media.
Recording was stopped.
- The file control information is corrupted or there was an encoder error. Turn the camera off and then on again. Then,
remove the card being used and reinsert it. Alternatively, replace the card. If this does not solve the problem, consult a
Canon Service Center.
* Corrupted file control information cannot be recovered. Cards or XF-AVC clips with corrupted file control information
cannot be read by the software (Canon XF Utility or plugins for NLE applications).
Some clips require data recovery
- The power may have been suddenly turned off or the card may have been removed while the camera was recording.
As a result, one or more clips contain corrupted data. You can try to recover the clips (A 48).
The following settings were changed.
- The settings displayed on the screen were changed automatically due to a change in one of the [Æ Recording/Media
Setup] settings. Check the settings before you continue recording.
The memory card is not compatible with the current recording settings.
- The camera is set to record XF-AVC proxy clips using slow & fast motion recording but the SD card used does not
have a UHS Speed Class rating of U3. Replace the card with one rated UHS Speed Class U3.
The number of ND filters used has changed. Check the focus.
- When using ND filter settings in the extended range (8 stops or 10 stops), the number of ND filters used changes and
this may result in a shift in focus. Check the focus before resuming shooting.
The video configuration was changed. Check the settings.
- Following the last change made to the recording/media settings, some of the video configuration settings were
changed automatically by the camera. Check the settings before you continue recording.
