With the cost of fast SATA hard drives at very low prices, we just capture 10bit uncompressed to start with and work in a 10bit timeline… no rendering.
Then we just use media manager to consolidate our clips and delete our unused stuff.
I highly recommend the Firmtek SATA boxes and, with 4 drives striped raid 0, we find we have plenty of overhead for all our 10 bit SD projects.
