Typically I advise that buying a camera is one of the last things a filmmaker does.
Development & Pre-Production can easily take 6-18 months for a feature.

Have you tried shooting w/ your phone first? No Joke.

An iPhone 6+ or 7+ w/ the beta Filmic app adds log support, AND
The optical + digital 4K in-camera stabilized video is plenty sharp to get started.
Recently an iPhone shot of mine was picked in favor of a RED Epic-D shot for a "thing" I was involved in.

Adding Apple file system support to Windows is easily done w/ third party utilities.

exFAT is not reliable; I've lost shots because of exFAT file system corruption.
It was intended as a stop-gap and designed for short term flash usb drives:

FCPx is a niche market product especially since Apple no longer makes workstations.
Better to stick w/ MCP and universal DNxHR to collaborate with Hollywood pros,
or go w/ Premiere for work with Indie teams.

Liz, for new apps/devices reported on NFS, it may be extremely advantageous for everyone to work w/ developers to offer a special discount to readers due to the shear attention articles like this often generate.

Something as small as a 7-day 10% discount may drive sales and promote faster adaption/try-outs.

Thanks again for posting.

Thanks for the heads up on this; I'll try it out.

FYI, it's not on Apple App Store.

Have to buy it directly: http://boardfish.io/

Alexander, this election went well beyond the bounds of political disagreement. Anyone w/ a passion for moving pictures, story, and characters, let alone one who calls themselves a "Director", should absolutely appreciate the grim reality of what America showed the world with the 2016 presidential election. The origins of story-craft are rooted in tribal/family attempts by elders to teach, educate, and enlighten - for the purpose of both a better today AND tomorrow. Not to tell anyone what to think, but to instill a sense of wonder, new thought, and appreciation of actions.

The USA 2016 election says: to win you need to be a hateful bully.
That message is absolutely unacceptable. Google: " hate crimes after election "

Alexander, I strongly suggest you consider narrative as a tool to improve ALL of humankind.

The pcie bandwidth figure I gave above WAS with short 0.5m cables. The issue is pcie allocated bandwidth in TB3, not total logical bandwidth. You'll only get full 40Gbps on TB3 if its pure data (nothing that requires pcie), and as you mentioned, if only using a short one foot and a half cable. An active optical will get you most of the way there at longer ranges, but will lose about 10% due to latency introduced with the optical conversion.

The best card in the latest MBP offers 1.8 TFlops. Thats less power then even an nVidia 960 (2.3TFlops). Speaking of the nVidia 960, that card in real world performance is nearly the same or better as the dual D700s on a nMP. While I disagree about OpenCL, as I have seen and made my own direct performance comparisons with 8K footage, the bigger problem is Apple doesn't have a single GPU offering that can best an nVidia 960 - Think about that.

Yes, the new new iMac "Pro" with dual vega will be pretty awesome, but its a last drop in the bucket thing for Apple before they drop intel, switch to their own processors, and eventually discontinue the entire Mac lineup.
