WorkMonkey Posted March 18, 2014 Share Posted March 18, 2014 I did my first real shoot with my BMCC 2.5k in studio last week using a Vertex 4 SSD and a Samsung 840 SSD. Perfect conditions - and yet they dropped frames like crazy. The Vertex far more than the Samsung, but both still did. Is this a write speed issue?

dhessel Posted March 18, 2014 Share Posted March 18, 2014 Yes. I am pretty sure neither one of those are on the official list of supported SSD's. Apparently SSD's can have fairly variable sequential write speeds that can drop too low causing the BMCC to drop frames. Here is a list of SSD's that should work without issue. Also be sure to format the SSD after every time you off load the footage, delete clips isn't enough as it fragments the drive and causes a drop in write speed. The BMCC need's a high stable sequential write speed or it drops frames. http://www.blackmagicdesign.com/support/detail/faqs?sid=27541&pid=27542&os=linux Link to comment Share on other sites More sharing options...

Even the recommended SSDs will drop frames if you don't reformat once you delete. Link to comment Share on other sites More sharing options...

WorkMonkey Posted March 20, 2014 Author Share Posted March 20, 2014 I tested the ProRes with those cards and it works fine - I'll have to check out the other SSD's for RAW. Posted about another issue with my Mark III and KomputerBay in the general forum if you know anything about that as well. Link to comment Share on other sites More sharing options...
hackerfilms Posted April 4, 2014 Share Posted April 4, 2014 I've tried a number of different SSDs and find the Sandisc Extreme is the most stable for my use. I just got a Samsung Pro SSD and it seems to be pretty stable as well. Did a 30 minute take with it and it was good as well. Link to comment Share on other sites More sharing options...
