Playback
•
Clips with HDR looks burned-in will not be correctly displayed on MVF and EVF
When playing back a clip that has a HDR look burned-in, it will not be correctly displayed on MVF and EVF, since both
are not HDR capable and no tone-mapping is applied. This is a monitoring problem only and does not affect the
recorded footage. However, we generally do not recommend burning in looks when shooting HDR content.
•
Internal camera playback of ProRes 4444 XQ clips
In camera playback of ProRes 4444 XQ clips may show jitter or a horizontally divided frame. The recorded clip is fine.
•
In Pause mode, interlaced clips only show half vertical resolution
This behavior can only be observed when playback is monitored on the SDI outputs.
•
Browsing clip list with camera buttons may not update clip selection in monitor
Using the buttons on the camera body for browsing the playback clip list, may not update the selection of the clip in
the clip list displayed in the viewfinder monitor.
•
Interlaced clips jitter vertically when played back with SDI output not set to interlaced.
This only affects the playback in SDI, the recording is correct. Make sure to always match SDI the output configuration
to the project configuration (e.g.: 60i clips to be played back with 60i SDI output).
•
Activating Playback does not disable peaking
Please disable peaking manually in case you do not want peaking during playback.
Recording
•
Camera sometimes does not prompt to format a non ARRI_UDF CFast card
While the MVF Display is set to live view mode, the camera will not prompt to format a CFast card, even the file
system on the card is not the ARRI_UDF file system, but FAT32, ExFAT or other.
•
Start recording from playback in MPEG or ARRIRAW mode
Starting a MPEG or ARRIRAW recording directly from playback can fail with error message: "Recording stopped due to
FPGA failure. Please reboot camera." Please exit playback before starting to record.
•
Noise Reduction in "Strong" mode
The "Strong" mode in Noise Reduction (available in S16 HD, 3.2K, 4:3 2.8K and 4K UHD) may result in image artifacts
with fast moving objects. We recommend testing this accordingly before using "Strong" mode.
•
Power loss during record with CFast 2.0 cards
A CFast 2.0 card may need to be reformatted when it is removed during recording or in the event of a sudden power
loss occurs while the camera is writing to the card. The camera will indicate the error with a warning message. Please
follow the instructions in the warning to avoid damage to the card or further recordings. No action is required if no
warning is displayed. Please contact ARRI service for more information or if you encounter any further issues.
•
Limited scaling quality in HD-SDI outputs when recording in 2K
The resulting image quality is considered as sufficient for monitoring but may be limited for recording the signal as the
master record. This is due to the downscaling of the 2K resolution to HD. Please set the recording format to HD when
recording HD on the HD-SDI output as master record.
•
Error message for maximum clip size.
On very rare occasions, the camera may stop recording and report "Recording stopped - maximum clip size reached".
This can only occur with image content that has very little detail and using a codec with low data rate like ProRes LT.
•
Changing Exposure Index or White Balance during record
When changing Exposure Index or White Balance during record it is possible that a single frame contains two different
image characteristics.
