AnyConnect Pocket Guid Reilly - Pocket Guide Pocket Guide SUP 8. The ALEXA platform has been designed with ease of use and user-friendliness in mind; the menu and controls are simple and intuitive, so the best way to learn ALEXA is to get your hands on the real thing. However, carrying this guide with you and combining it with other resources such as the ALEXA manual at www.

XR Module? Neutral color balance at all densities? High image sharpness and contrast Plug and play anamorphic? Strong and rigid 15 mm rod construction? Frames are not displayed, instead the time base of the timecode is shown in small digits.

Consists of I clip index and clip counter. Shown as h:mm:ss. Consists of I camera index and reel counter. Marks the active card. The camera is recording. Recording is not A possible. Press the INFO button for more details. Calculated for the set frame rate and codec. Note: these are only approximate values.

An error occurred. Turns orange during card access. Still frame is being captured to the SD card. A new still frame can only be captured when this is completed.

Should only be used in very humid conditions e. WRS radio is active. Image quality might be affected. Great sensor temperature offset. Image quality might be affected seriously. Camera is locked. Smooth mode active on EVF. Home screen is locked. Grab 14 Stil frame is being captured to the SD card. To record above 60 fps in any format, the camera needs to be switched to high speed mode. Actual data rate and recording time varies depending on image content.

This feature will be re-enabled as soon as possible. It offers the highest achievable resolution, the camera's natural color response and great exposure latitude as uncompressed and unprocessed sensor data. A color reconstruction algorithm calculates the missing components of each pixel based on the type and position of the array of colored filters Bayer pattern on the camera sensor. As a result, half of the reconstructed image's green values are interpolated from the surrounding photosites rather than captured, as are threequarters of the red and three-quarters of the blue.

For VFX, however, the images often are processed using the native sensor pixel count and then downscaled to 2K, for example, at a later stage. Using this approach takes advantage of the luminance resolution, which correlates to the sensor pixel count.

Right now the ARC is undergoing a complete overhaul. A totally new user interface in combination with a feature rich tool palette will offer a more intuitive use and better when working with ARRIRAW footage. Please note that for all image processing parameters such as sharpness, color etc. With SUP 7. 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.

With the option to capture ProRes 2K in the aspect ratio1, the format offers true anamorphic capture with regular anamorphic lenses and offers extra room for repositioning when using standard spherical lenses. This allows the use of an optimized in-camera downscaler and provides the best possible 2K image output. The actual data rate varies with the image content.

An MXF container file can "wrap" different types of video and audio material along with associated metadata. This is ideal for both camera acquisition and archiving since audio and video is always kept together and no data is lost if recording is interrupted for any reason.

This feature will be re-enables as soon as possible. These values are for Log C. Rec has 0. Otherwise they are the same. Traditional ND filters should only be used up to an ND 0. A single filter that combines a ND and a far-red cut off generally yields better results and fewer reflections than a traditional ND filter stacked on top of a separate IR-cut off filter.

In comparison to other IRNDs which have some bumps in their spectral behavior or the ordinary ND which opens up at about nm the FSNDs offer a true even reduction over the whole spectrum see next page. The advantage over classical ND filters is that it is located behind the mirror shutter, so the optical viewfinder image stays bright. The false color exposure check is based on the color processing set for the respective output signal path.

So if you have the viewfinder set to Rec , the false color exposure check will be based on the Rec image. Cineon was the digital film scanning, processing and recording system developed by Kodak in the 90s.

It is also the name of a file format that contains density data from scanned negative film. Density is a logarithmic measure of the opacity of the film. Each stock has its own characteristic curve, but the overall shape is always the same.

With Log C encoding, the signal level increases by a fixed amount with each increase of exposure measured in stops. Viewing and Monitoring Log C Shooting images in Log C delivers the best basis for the colorist's work, as it provides the camera's full latitude in an unconfined color space.

When viewed directly, Log C images look flat with desaturated colors. To correctly display Log C material on an HD monitor Rec or in a digital projection P3 , it needs to be tone-mapped and transformed into the target color space.

The top quality codecs ProRes HQ and DNxHD x will also provide acceptable results in Log C, but due to the higher compression ratio, grading images recorded with these codecs may exhibit artifacts. Linear Visual effects often work with linear light encoded material. The linearization will preserve all image information. It is therefore possible to do round-trip conversions from Log C to linear and back to Log C.

It is available online at www. Optionally, a look file may also include a freeform curve grey scale tone map LUT that will be applied instead of the standard Log C to Video tone mapping curve. One Look File can be activated at a time and applied to the different image paths individually. As soon as a Look File gets applied to any output, the data of the Look File is stored in metadata. The LUT on the other hand is used e. Color correction settings that were made during the shoot are logged with time code and can be output in an Avid Log Exchange ALE file.

The ALE file then can then be used in a color correction system to automatically apply the color corrections when deliverables will be created. The Codex VFS can use the color correction settings and automatically apply them when generating files. In an extended range signal, the same range is represented by code values 4 to Extended range encoding does not provide a higher dynamic range, nor does legal range encoding limit the dynamic range that can be captured.

It is only the quantization the number of lightness steps between the darkest and brightest image parts that is slightly increased about 0. The same applies for 8 bit range or 12 bit range signals. Most editing or post production tools automatically transform the legal range files to e. Note: Some recorders will allow to record e. ProRes clips in extended range. The psf mode splits each frame into two segments other than interlaced capture, which captures both segments in two separate exposures.

The psf output enables compatibility to devices that only understand interlaced signals for certain frame rates. ALEXA always records as much metadata as is available.

This additional information makes documentation easier as the metadata is stored within the image files so it cannot get lost. A range of automatic and human-readable data is being delivered by the ALEXA camera; this data makes work in post much easier: exposure index, gamma and white balance information, for example, is essential for creating dailies or color grading. Reel number, project fps, date and time become important when combining images and sound from different sources.

These atoms or text based files can be parsed by e. For more information on the metadata have a look at our whitepaper at www. A guide on how to create an entry for an unknown lens can be found on page Lens Data creation 2. A license file is serial number sensitive and can only be used on the camera for which it has been purchased. This mode uses the same Super 35 sensor area as Regular Speed mode same depth of field, same angle of view.
