This is why i wish the C200 had 4k raw out of either SDI or HDMI, so i could bypass expensive cards, and just use an external recorder to record the raw files (or prores / DNxHD) to SSD's. Then edit straight from the SSD's.
Not practical for you run & gun guys, but if you're on a tripod or shoulder mount then the extra weight wouldn't be such a big deal. And 1TB ssd's are so cheap now![]()
Just use a CFast to SSD adapter like folks are using on the BM Ursa Mini's.
