Got 8K footage for the first time just 2 days ago (we are doing Postproduction) The first thing we did is convert everything to 2K EXR because 8K is just plain stupid. It took us 6 Hours to copy everything off the Harddrive and a than another 11 HOURS or so to just convert it to something usable(all billable so I dont really complain) We dont usually get RED footage these days anymore, only on music videos and Indie stuff, so we dont have a rocket. And yea with this camera you HAVE to shoot at 8K if you want the full sensor ... stupid device nobody wants, just use a alexa/mini in 2K mode, it will look better and your postproduction will be WAY cheaper. I still do not understand why anyone would ever shoot anything on red anymore when there is a Alexa Mini...
Funny, had the editor in one of our editing suites the other day, cool guy, really liked him, also it was one of the most complicated avid loads ever, very cool approach!
I have used controlermate to map the BCR2000, it did work, but its a huge B**** to set up, but if you have the time , go ahead I have never finished it sadly!
(I now have a Elements Panel at work).
