Operation of the Camera 14 123 Operation of the Camera This chapter covers tasks the user will encounter while using the ALEXA. While previous chapters contained specific procedures for basic use, this chapter will outline broader tasks and offer recommendations and best practices, including camera configuration. 14.1 Internal recording This chapter contains information and recommendations for internal recording.
Operation of the Camera NOTICE Recording ARRIRAW internally works only with SXR/XR Capture Drives. ProRes Recording in ProRes 2K is a cost-efficient alternative to shooting ARRIRAW, as it requires less storage space and no processing, but at the same time delivers an image quality that is superior to that of up-scaled HD material.
Operation of the Camera 125 ProRes RAID for SXR Capture Drives When SXR Capture Drives are being formatted for ProRes in the ALEXA SXT, essentially the same happens, but since SXR Capture Drives contain four internal SSDs, a combination of RAID 1 (mirroring) and RAID 0 (striping) is used, commonly referred to as RAID 10. Drives zero and one will be combined into one RAID 1 volume and drives two and three into another. This provides redundancy.
Operation of the Camera NOTICE CAUTION! RAID redundancy is very helpful if data from one of the two internal drives is corrupted or one of the internal drives is damaged. But the XR or SXR Capture Drive still appears as one volume, and if it gets erased accidentally by the user, the data is gone.
Operation of the Camera 127 Sensor Mode Resolution 3.2K (3168 x 1782) 6:5 2.6K (2578 x 2160) 4:3 2.8K (2880 x 2160) Open Gate 3.4K (3424 x 2202) The camera will automatically calculate a CRC32C checksum for the image data inside each ARRIRAW frame. This checksum is recorded onto the SXR Capture Drive or XR Capture Drive where Codex software uses it to verify the image content during all copying and processing steps. In addition to providing extra security, this also speeds up the copying process.
Operation of the Camera 5 6 Verify data Format Format Before recording, the drives/cards must be formatted. The camera always performs a blank format, which means that the media contain no metadata and are not assigned a reel number prior to recording the first clip. The camera auto-detects media with an invalid file system and asks the user to format the media. The ALEXA uses the UDF file system for ProRes recording and the Codex file system for ARRIRAW recording.
Operation of the Camera 129 The XML file is a Final Cut Pro 7 (FCP) XML file. When opened in Final Cut Pro 7, all clips are imported as one bin. If the clips are copied from the card to another destination, the file paths in the XML file have to be adjusted to match the new file location. The XML file is not compatible with FCP X. The ALE file is an Avid Log Exchange file for Media Composer. It contains all static clip metadata, which is also embedded in each recorded clip.
Operation of the Camera The file name consists of 6 parts: • Camera Index: One character, A-Z. User assignable, should match the camera unit. For example, the camera index A can be assigned to the A camera, and B to the B camera. • Reel Counter: 3 characters, 001-999. Auto-assigned to each drive/card, automatically advanced by one for each new drive/card. The user can change the counter for the next reel.
Operation of the Camera • • 131 On SxS cards, use the write protect tab before sending it to the data wrangler. After an SxS card has been downloaded and backed up, disengage its write protect before formatting. Metadata Metadata is stored in a Final Cut XML file, an Avid ALE file, in the recorded frames/ clips and embedded in the HD-SDI signals. The most important metadata for post production workflow is the tape name, as it will be one of the primary identifiers used in the EDL.
Operation of the Camera 14.2.2 Status Info Overlays The ALEXA can display camera status information on EVF-1 and MON OUT. At the top and bottom of the screen, the ALEXA displays textual status information. The top status bar consists of sensor FPS, shutter angle, exposure index and white balance. In the EVF-1, the status bar also works as a menu, allowing the user to change the values when the CAM button is pressed.
Operation of the Camera 133 Indicates that the current recording mode is set to ProRes. Indicates that the current recording resolution is set to 4K Cine Anamorphic. Indicates that the current recording resolution is set to 4K UHD. Indicates that the current recording resolution is set to 4K Cine. Indicates that there is a warning condition in the camera. Warns that the camera has detected an error. Indicates that the camera temperature is outside of its optimal range.
Operation of the Camera Indicates that the current recording mode is set to ProRes. Indicates that the signal from the RET IN connector is currently being displayed. The following table explains the icons in the MON and EVF group on the right: Icon Description Indicates that the processing of the respective output is set to Log C. Indicates that the processing of the respective output is set to ARRI Look File 2 file. Indicates that the processing of the respective output is set to ALEXA Classic 709.
Operation of the Camera 135 External TC, Time of day Use: This format is often used on multi-camera productions with sync-sound. When all cameras are running at sync-sound speed, which is also the project frame rate, sound and image time code match and allow for easy syncing in post. Setup: The sound department acts as the timecode master, and generates timecode which uses the time of day as a value, and a time base matching the project frame rate.
Operation of the Camera To sync the sensors of two ALEXAs: 1. Connect an EXT cable KC 155-S to the EXT ports on each ALEXA. 2. In the System menu on the master camera, select External Sync. 3. On the EXT SYNC screen, set Sensor sync to EXT master. 4. In the System menu on the slave camera, select External Sync. 5. On the EXT SYNC screen, set Sensor sync to EXT slave. It takes approximately five seconds for the two ALEXAs to sync.
Operation of the Camera 14.5 137 Syncing the Settings of Two Cameras Two ALEXAs can be operated with synchronized settings. ARRI recommends to sync the settings of the same ALEXA models only, for example, two ALEXA Plus models. Camera connection The settings of two ALEXAs can be synchronized over ethernet using the ALEXA Ethernet/Ethernet Cable KC 156-S, or over an ethernet hub using the ALEXA Ethernet/RJ-45 Cable KC 153-S.

ALEXA SXT Studio 17.2 159 Optics 17.2.1 Electronic Mirror Shutter The electronic mirror shutter is located between the PL-mount and the image sensor at an angle of about 45°. It is part of the optical reflex viewfinder system that reflects the lens image into the optical viewfinder. It is synchronized with the electronic shutter of the camera sensor so that the sensor is only read out in the dark phase. This completely removes rolling shutter effects of the sensor readout.
