An internal buffer in the camera is used to record a perpetual loop, the length of which depends on selected options. When the REC button is hit, the clip recorded to the CFast 2.0 card will include the specified pre-record period at its start. 25 fps 30 fps 50 fps 60 fps 100 fps ProRes 422 LT (HD/2K) ProRes 422 (HD/2K) ProRes 422 HQ (HD) 20 sec 16 sec 10 sec 8.3 sec 4.9 sec ProRes 422 HQ (2K) 18 sec 15 sec 8.3 sec 7.4 sec 4.3 sec ProRes 4444 (HD) 13 sec 11 sec 6.7 sec 5.5 sec 3.2 sec ProRes 4444 (2K) 12 sec 9.9 sec 5.9 sec 4.8 sec 2.8 sec Pre-Record: Maximum Recording Times Pre-record function When using a Lens Data System®(LDS) lens on AMIRA’s PL-LDS mount, data about iris, focus and zoom positions will now be visible in the viewfinder and all lens data will be embedded in the recorded QuickTime files. TECHNICAL REFINEMENTS AMIRA’s HD-SDI output has been refined to allow the overlay of information about timecode and other parameters that is seen in the viewfinder, to also be seen on monitors. Additionally, it will now be possible to use an HD-SDI signal input as a further ‘genlock-like’ sync option. Enhanced HD-SDI outputs An improved debayer algorithm for AMIRA will now result in an even greater reduction of aliasing and noise, for smoother images. Improved debayer USER REQUESTS AMIRA already boots up faster than ALEXA, but AMIRA users asked if it could be sped up even more. These requests were made a priority for SUP 1.1, resulting in a more than 25% reduction in the camera’s boot-up time. Faster boot-up time Some AMIRA users with an ENG background requested a waveform display on the camera’s viewfinder image and LCD panel. This has duly been implemented, with the option to have the waveform full screen, or covering just a portion of the image, providing a further tool for judging exposure levels. Waveform display From SUP 1.1, AMIRA will be able to generate a color bar that is viewable in the viewfinder, on the camera’s LCD panel and on any connected monitors, allowing those monitors to be calibrated to match the viewfinder.
