Hi !

I know there is no official decision made at the moment about recording and compression. But want to think about a good software solution which should have a EDL and XML interface for conforming and a good possibility to render rushes. A good thing would be that the SW should work via Hardware acceleration on the graphics card for debayering or an extra card which both should give you realtime full debayer processing. Using the graphic card for speeding up rendering and preview would be nicest version.
A commandline interface would be also very nice.....

MAC and Windows based

thx

Dear Rainer,

ARRI offers a Software called ARC (ARRIRAW Converter) which is after registration available for free download under:

http://www.arridigital.com/technical/imaging-technology/arriraw/converter

ARC converts ARRIRAW images into DPX files and also supports EDLs. The preview viewer in ARC uses GPU acceleration. ARC is currently available for Win32 and Linux64. Both versions can be used as command line tools, the Win32 version comes also with a GUI.

Several partners provide ARRIRAW capable tools and equipment as well. A list will be provided soon.

Regards

Thanks for the information. Would you plan at least a command line tool for MAC? Our house is mac based, so we have to install a windows machine too with a proper performance. Also for on set working, would be nice to have the possibility to stay on our system line....
A complete list with all the software providers would be great to see what products are on the market.
When the new cameras will come we want to have a bullet proof workflow from the first day!

So will there a update on the existing ARC that it will support the compressed version of ARRI RAW too ?

You wrote it will export DPX. So think also please on offline editorial as well. The possibility to export AVI, Quicktime and most important for all Avid editors is MXF export, burn In, etc.

thx

The RAW converter is a good start but it's only an initial solution and does not solve the many issues facilities have working with RAW data in post.

Having been involved in post on many large budget films ($40-100M+) I have to say that RED got is about as wrong as they could have by encrypting a simple JPG2000 data stream and then forcing the world to buy expensive "Rocket" decoding cards. 

I sincerely hope that Arri does themselves a favor and does not do this.  RED did not make any friends in the post and VFX arena when they kept the content of the mysterious R3D format so secret and when it was discovered that R3D was just JPG2000 a lot of people were really pissed.  Why encrypt an open codec and make everyone's life miserable?

That said, the workflow can be very good with R3D.  Tools now exist to allow you to edit with quickly transcoded editorial friendly formats (using the Rocket, not the GPU as it should) and to re-conform and grade using the original camera source RAW files.  This is a step in the right direction and would have been a big win were it not for the encrypted file format which has complicated each step in post where you would want to use the RAW files directly.  Encrypting the R3D format stifled development of workflow improving tools in the marketplace and has made a lot of places shy away from the camera until they can decode in real time with their own proprietary tools (most major post facilities utilize a dizzying number of custom tools in their pipelines).

If Arri wants to make a lot of people happy, they will remember that almost every MAJOR post facility, from ILM & Sony to DD, to all the small shops in LA are almost exclusively on Linux.  Editorial is done on Macs and there is a small and shrinking amount done on Windows.  That means a solid SDK and API for the codec for Linux, OSX and Windows are ALL essential. 

Having the ability to debayer and decode on the GPU and developing the format so it can be quickly transcoded to editorial friendly formats like ProRes422 as well as OpenEXR (standard for Visual effects) and allow for conform and grading using the original raw data to eliminate generational loss would complete the circle.
