Recording media and media stations play an integral part when it is time to set up your ideal production workflow. ARRI offers a selection of recording media that has been catered specifically to offer the best recording performance with ARRI cameras. All supported media combine speed, capacity and performance – the factors required for the recording of high-quality camera footage.
Having a track record of our own, in all areas of the production process, we understand the importance of a straight-forward workflow. This understanding is what enabled us to make the ALEXA camera a complete game changer. For the first time, productions could record high-quality footage in a ready-to-edit production-quality codec, directly in a digital cinematography camera. We never lost track of this fundamental understanding an continue to introduce new ways of making life easier from set to screen.
Offloading problems with older CFast 2.0 cards
Due to the information we have received during our regular market observance and our investigations, we have to take back our recommendation to use Lexar Professional 3600x CFast 2.0 cards for recording in ARRI cameras. The cards will continue to work in our cameras, but we cannot unreservedly recommend their use any more.
ARRI does not want to give the impression that all Lexar cards are affected. Many customers have been using the Lexar 3600x CFast 2.0 cards for years without experiencing any problems. In fact, only a few users have experienced the aforementioned issue. Therefore, it would be premature to replace every card currently in use. First and foremost we wanted to insure that our customers were made aware of this concern so they could identify a problem at its first occurrence and take the effected cards out of circulation immediately.
The complete information is posted in the ARRI Forum. Please let us know if you have any further questions.
What are the different methods of clearing data of Recording Media?
There are two methods for clearing old data from a recording medium with ALEXA SXT cameras: Quick Format and Erase. For technical reasons, most media allows only one of those methods. Quick Format erases only the file allocation table, but leaves the actual data still on the card. Quick Format is therefore the faster method. Erase takes longer than Quick Format, but ensures that all data on the card is erased. Using Erase with SxS PRO/PRO+ cards can increase their write speed.
Which Recording Media can I use with ALEXA LF?
When first released, the ALEXA LF (with Software Update Package (SUP) 2.0 or 2.1) could record to SXR Capture Drives 1TB and 2 TB (ProRes or ARRIRAW). Since LF SUP 3.0 it can also can record to SxS PRO+ 256 GB cards (ProRes only).
Does ProRes recording to SXR Capture Drives on the ALEXA LF work as it does on the ALEXA SXT W?
Yes. SXR Capture Drives used with the ALEXA LF will have the same ProRes recording behavior as with the ALEXA SXT W: ProRes is recorded in a RAID configuration and the same hardware tools, software tools and methods can be used. As with the other ALEXA cameras, SXR Capture Drives can record ARRIRAW or ProRes, and SxS PRO+ cards can record ProRes but no ARRIRAW.
Why do you not support XR Capture Drives, CFast 2.0 cards or smaller capacity SxS PRO cards?
This is because the slower and smaller capacity media don’t make sense with the higher data rate of ALEXA LF, and because we wanted to reduce complexity and testing time.
Why is there a limit to the clip length in ProRes?
The UDF file system used by all ALEXA cameras (except for ALEXA Mini) for ProRes recording has a QuickTime/ProRes file size limit of 229 GB. This limits the length of each clip based on the sensor mode/fps settings. This is the same for SXR Capture Drives and SxS PRO+ cards.
Will CFast readers other than the CFast 2.0 reader sold by ARRI work with CFast 2.0 cards supported by the camera?
Yes, other readers following the CFast standard work with the CFast 2.0 cards supported by the camera.
