Using this approach takes advantage of the luminance resolution, which correlates to the sensor pixel count.ĪRRIRAW SDK and 3 rd Party Implementations In many cases, ARRI's SDK is fast and adaptable enough to satisfy the processing needs of an application. Generally speaking, a simpler algorithm will process faster, but also involve a higher probability for color errors.įor VFX, however, the images often are processed using the native sensor pixel count and then downscaled to e.g. The output quality of the image depends on the de-bayering algorithm. Half of the reconstructed image's green values are interpolated from the surrounding photosites rather than captured, as are three-quarters of the red and three-quarters of the blue. The image above shows a single-channel capture from the sensor on the left and on the right the reconstructed image facilitating the color filter array.
Older ALEXA cameras (ALEXA Classic, ALEXA Plus/Plus 4:3, ALEXA-M and ALEXA Studio) require an ARRI-certified external recorder which understands the T-Link signal. MXF/ARRIRAW is ARRIRAW within a container format (*.mxf), hence one clip is only one file as opposed to some thousand files with every file being a single frame in the regular ARRIRAW format *.ari. Our camera line-up supports in-camera recording of ARRIRAW or MXF/ARRIRAW data. This makes ARRIRAW the perfect format for digital cinematography and high quality visual effects production. The originally recorded raw data remains pristine, always providing the flexibility to go back and refine the results. Like film negative, ARRIRAW data has to be developed – or rather processed – in order to convert the single channel image, which represents the raw Bayer pattern sensor readout, into a color image suitable for normal viewing. ARRIRAW is the only format that retains the camera's natural color response and great exposure latitude as uncompressed and unprocessed sensor data. It can be considered a digital version of the camera negative. ARRIRAW is ARRI’s format for uncompressed, unencrypted and uncompromised sensor data.
