Page 56: Timecode
Main Parameters Automatic White Balance Automatic white balance calculates the white balance based on the camera's live image and overwrites the active white balance value. The result is stored as first entry in the WB list. Automatic white balance can be triggered through a dedicated button in the white balance screen or through a user button assigned with Auto WB. - Page 57 Main Parameters Rec Run Timecode Use: Rec run timecode is often used on single camera productions that are either MOS or use a dumb slate to sync picture and sound. Record run timecode guarantees contin- uous timecode on all recorded data. Record run timecode also works with over- and undercranking.
- Page 58 Main Parameters Depending on the timecode run mode, regen behaves differently: Regen Run mode rec run: The camera determines the timecode of the last frame of the last recorded clip and increments it by one for the next clip. This ensures consecutive timecodes for a sequence of clips.
-
Page 59: Look Settings
After recording, backup and data transfer the look can be extracted from the clip’s file header using the ARRI Color Tool again. This way the look can travel to post production as an ARRI Look File 2 or as a 3D LUT. - Page 60 ARRI Look File 2, as the camera does not take into account which ARRI Look File 2 was active when the clip was recorded. It is the responsibility of the user to make sure the correct ARRI Look File 2 is applied during playback.

ARRI customers like. Using ARRI Noise Reduction ANR-1 enables you to use noise reduction on set in the camera. This can be helpful for low light shots, where an in-camera noise reduction is a very fast solution. Furthermore, ARRI Noise Reduction ANR-1 gives you the possibility to combine the amount of grain with your sharpness and detail settings for the chosen exposure directly on set. -
Page 95: User Pixel Masking
20.3 User Pixel Masking All sensors exhibit a certain number of defect pixels, and ARRI cameras have two mechanisms to catch and correct them: one is a static pixel correction based on a pixel mask created during manufacturing, and the other is a dynamic pixel correction that continuously evaluates each frame and masks defect pixels that are not caught by the static pixel mask. - Page 96 Sensor Settings As an added service, it is possible to send the User Pixel Mask to ARRI Service at service@arri.de for verification. We strongly recommend that you take advantage of this free service, as sometimes, clusters are difficult to spot depending on the background. Please note, however, that in the end, it is the responsibility of the person creating the User Pixel Mask to verify that no clusters are formed.

Page 108: List Of User Button Functions
User Buttons Smart Behavior Some user button functions support smart behavior. For these, a short press (i.e. less than half a second) toggles the function, while a long press (i.e. longer than half a second) activates the function only temporarily, as long as the user button is pressed. Assume a user button is configured with EVF Zoom: Short press of user button: EVF zoom is activated and stays activated. - Page 109 User Buttons User Button Functions SDI Zoom (smart) Press SDI Zoom to activate the zoom function on the SDI outputs. Further button presses change the Zoom position. A button longpress exits the Zoom function. EI Increase Selects the next value from the EI (exposure index) list. EI Decrease Selects the previous value from the EI (exposure index) list.
