ARRI Alexa in the NetherlandsPosted by Bastiaan Houtkooper in Untagged |
Today the first Alexa in The Netherlands (and one of the first in the world) was delivered to Camelot. Some preliminary testing has led us to believe that it is a very nice and beautiful camera. This model includes formats in the menu: ProRes 422 HQ ProRes 4444 both formats are still in beta testing. HD 422 single link and 422 dual link are also able to manage 60 fr/sec and of course 444 come from the HD-output. It is possible to select ‘legal’ or ‘extended’ mode, as well as the T-link option which is the real ARRI raw signal, but we are still not equipped to shoot with this option. At the moment I think only 2 recorders can manage these flow data and they are quite expensive. All HD outputs are 1.5Gig, and 3Gig later on.Because the output is now ARRI RAW LOG instead LIN like the D21, all recorders need to be update and certified again.
The camera runs at a maximum of 30 fr/sec, except with the Dual link 422 HD output. It is possible to select REC709 gamma or LogC, which shows the uncorrected output. We have seen the ProRes-material on the Barco 90 projection, and this indeed shows a difference in noise between 422 and 444. Furthermore, the image is extremely attractive to the eye, with very fine grain’ , beautiful colors and excellent contrast, when captured with REC709.
The viewfinder has also improved from how it was in the prototype model, with a better view angle and a cleaner, clearer image. An added advantage is that the functions like zoom, white balance, etc. are local, and therefore not visible on the monitor output. Camera start-up time is 15 seconds, formatting in less than 10. The only part which was somewhat slow, in my opinion, was the time in between touching the REC button and the actual recording.
The menu is transparent (adjustable) just like the buttons, although the white print is difficult to read. It's easy to work the camera without consulting a manual, it's all simple and straightforward. Most common functions are located under direct buttons and user buttons can also be allocated. Although the body is comparable in size to the RED, the battery and other parts are very compact, making it feel like a much more portable camera.
There is a small foam pad to cushion the shoulder, which could be improved. The balance of the camera is quite tolerable. The viewfinder comes with an extension piece that can be attached to the back of the camera with a support, which is a very nice option. The viewfinder also has a standard heated eyepiece.
The SX cards copy rather quickly. In 444 PRoRes it is possible to record 2 x 15 minutes, and view it in realtime on a laptop in a short amount of time. This camera is also very nice for people who get anxious around complicated cameras with a lot of buttons or digital cameras. The operator side holds a minimum amount of buttons, which can be appealing to a lot of filmmakers. The workflow is also simple with ProRes. One of the tests yet to be done is finding out if running LogC on HD444 produces something extra. Hopefully we can still borrow an ARRI RAW camera to see the difference.
