Page 56: Main Parameters
Main Parameters Main Parameters The following chapter lists the most important parameters of the camera. 14.1 Project Settings The project settings menu contains settings that should be configured at the beginning of each project and can be found at MENU > Recording > Project Settings. Project Rate The project rate determines how many frames the timecode counts per second, and also determines the frame rate at which clips are played back. - Page 57 Main Parameters Camera Index Color Set the color of the camera index letter displayed in the Status Info of the SDI outputs (e.g. to match it to the color coding of your cameras). ► Select MENU > Monitoring > SDI > SDI Processing > Overlays > Status Components > Camera Index Letter to display the camera index letter in the SDI status info.
-
Page 58: Sensor Frame Rate
Main Parameters 14.2 Sensor Frame Rate The sensor frame rate determines the amount of frames generated by the sensor in one second. For sync sound recording, the sensor frame rate matches the project speed. If you record a clip at a higher sensor frame rate than the project rate, a slow motion effect occurs during playback. -
Page 59: Exposure Index
14.4 Exposure Index The Exposure Index (EI) is the applied sensitivity of the camera. The ALEXA Mini LF has a base sensitivity of 800 ASA. This means that the dynamic range is almost evenly distributed above and below neutral gray with low noise in the shadows and clean, smooth clipping behavior in the highlights. -
Page 60: Nd Filter
14.5 ND Filter The ALEXA Mini LF has a built-in motorized and sealed filter stage for Full Spectrum Neutral Density filters (FSND) with densities of 0.6, 1.2 and 1.8 (and an optical clear filter). In comparison to IRND filters, which have an uneven spectral behavior, or to an ordinary ND filter, which opens up at about 675 nm, the FSND filters offer a true, even light attenuation over the whole spectrum. - Page 61 Main Parameters Timecode Run Mode Rec Run timecode is often used on single camera productions that are either MOS or use a dumb slate to synchronize picture and sound. Rec Run timecode guarantees continuous timecode on all recorded data. The timecode increments only during recording, by one frame for each image generated by the sensor.
- Page 62 Main Parameters The camera samples the timecode from the timecode connector and simultaneously tunes Jam Sync its internal timecode clock to match the clock of the timecode source. During this procedure, the timecode display on the HOME screen, on the timecode menu screen as well as on the Status Info is blinking.
- Page 63 Main Parameters ADVICE The camera's internal battery will keep the timecode and timecode tuning values for about 5 minutes after the power source was disconnected.
-
Page 64: 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 65 Please note that this is the currently enabled 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.

Select to apply the look set in MENU > Look > Look to the output path. Look Applies a video display processing to camera images. The default ARRI 709 look complies with the ITU.R-BT709 standard for display on standard broadcast monitors. -
Page 67: Noise Reduction
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 68 MXF/Apple ProRes files cannot be opened and altered in the ARRIRAW Converter (ARC). When recording MXF/ARRIRAW files, the ARRI Noise Reduction ANR-1 is applied for preview (viewfinder and SDI outputs) but not baked into the footage, instead it will be stored in metadata.

Page 93: Preventing Damage To Sdi Outputs
Problem Description Camera SDI outputs can get damaged when an accessory is connected to the SDI output and is powered through an unshielded cable. All cameras, including all ARRI cameras and other SDI devices, can be affected by this. This is especially critical for cameras with SDI connections capable of SDI 6G or higher (even if set to work at lower bit rates like SDI 1.5G). - Page 94 Monitoring ADVICE Always make sure to plug in the power cable first and then connect the BNC cable. Once power and BNC cables are connected, it is OK to power the camera or accessory on or off. Always make sure to disconnect the BNC cable first and then disconnect the power cable. Only use shielded power cables to power accessories that connect to the camera with a BNC cable.

Page 101: Synchronization
Synchronization Synchronization The camera's sensor and SDI outputs can be synchronized to either a genlock signal (a tri-level HD signal or an analog black burst signal) present at the BNC SYNC IN connector or a timecode signal present at the 5-pin LEMO TC connector. The camera's sensor needs to run at equal or double the frame rate of the reference signal to establish synchronization. -
Page 102: Ext Sync
20.1 EXT Sync Up to 16 ALEXA Mini LF cameras can be synchronized for various applications requiring sensor synchronization. One camera is set as the host camera and the other cameras function as client cameras. Cameras can be connected to each other via the EXT connector, using the MINI-EXT-sync cable (K2.0009051) and the EXT Distribution Box EDB-2 (K2.0013145). - Page 103 Synchronization EXT Sync Mode One camera is functioning as the host camera and the other camera(s) as client camera(s). A client camera can be a sensor client (only sensor synchronized) or a settings client (sensor and settings synchronized). ► Connect the cameras via their EXT connector using the MINI-EXT-sync cable(s) and the EXT Distribution Box EDB-2.
- Page 104 Synchronization ► When using settings client, each camera in the setup needs to use an individual camera ID prefix. Select MENU > Recording > Project Settings > Camera ID Prefix and select an individual prefix for each camera (usually giving the host camera the camera ID prefix “A”) Media Status with EXT Sync The host camera calculates the overall remaining recording time based on the media with the lowest capacity in the cluster.

When shooting ARRIRAW, it is not necessary to load the User Pixel Mask into the camera. Instead, it can be applied to the ARRIRAW files in post production using the ARRI Reference Tool or any third party software that has implemented the User Pixel Mask feature through the ARRI Image SDK. - Page 107 Sensor Settings ► Use the ARRI Reference Tool to mark defect pixels. The marked pixel coordinates are stored in an XML file called the User Pixel Mask. Please note that it is advisable to mark the least number of pixels necessary, as too many marked pixels can be counter productive.

Through AMB we’re closely working with VFX tool manufacturers for years now to enable and enhance their systems to auto-sense e.g. lens data in ARRI original camera negatives and use it to trigger e.g. a de- focus effect. - Page 118 Metadata ADVICE Export laws dictate that for sensors made up of more than a certain number of photo sites, we cannot record positional information like tilt and roll, lest the camera be classified as military equipment. This rule looks at the total number of photosites on the sensor and does not concern itself with individual recording formats that may record fewer photosites.

Page 132: Appendix
Appendix Appendix 29.1 Sensor Related Information / 有关影像传感器的信息 Single Frame Spots of Various Shape – also known as “Digital Dust” or “White Flecks” Natural and/or artificial radiation may cause a “false exposure” on the image sensor. The shape of these spots may vary from dots to lines or other, sometimes irregular shapes. These spots occur in random locations of the image, last only for a single frame and are more visible in dark images. - Page 133 曝光时间越长，这些像素会变得越多。当曝光时间长于 1/24 秒时，请仔细检查画面是否符合您的要求。 Stitching with ALEXA Mini LF The ALEXA Mini LF sensor consists of a large sensor structure that is created by exposing two Super 35 sensor structures side by side onto a silicon wafer. This process is, somewhat misleadingly, called “stitching”.
