I think the whole “plug it directly into the computer” thing is all moot when it works perfectly fine in Apple Color, but has latency in Resolve – ON THE SAME MACHINE

hey Jake
did you use the Artist with Apple Color? I feel like I wouldn’t have noticed the lag in Resolve if I hadn’t spent 6 months using it with Color. It’s night and day the difference.

I’m with ya, completely disappointed in the lag. I’m still running Resolve 9.1.4 and EuCon 2.7 because of the issues people have reported. the 9.1.4 and 2.7 combo is actually very stable, but the lag has never gone away. I bought the board because it worked with Color and Resolve (back when I still had a number of Color projects) but disappointed in how much slower it is with Resolve. Since it’s been this long without a fix, I’m holding no hope for the future. I’ve gotten used to the lag, but it makes me stare at the waveforms and YRGB numbers on the GUI more than I want because I never know if my movements are being applied to the grade. Oops, there it goes, now I gotta dial it back. Dammit!

you might want to jump over to the Resolve forum for specifics, but since you mentioned a Rocket, I thought the bulk of your work would be RED. If you’re doing more Alexa, then you’re correct that three 580s will be faster than a single Titan. I should also mention that some are having issues with the Titan on their Mac Pros, jump over to the Resolve forum. you don’t need a GUI card in Resolve 9 or 10. running GUI off the GPU only slows it down by a tiny fraction.
with 10GbE, i think you’ll see more like 650MB/s real world. how many MB/s is your current Resolve system pulling when it’s rendering Alexa footage?
i would look at all the components in the chain, and try to figure out where your bottlenecks are in a typical workday. would faster storage help? would faster GPUs help? do you really need to render at 110fps to get your work done? where can you compromise and get away with it? personally i like redundancy. if something happens to your Resolve system, it won’t stop the card offloading process if it’s running on another computer.

it might not be a bad idea to get 2 Mac Pros and tie them together with 10Gb Ethernet. A Cubix costs as much as a Mac Pro anyway. one MP with Red Rocket, Titan, BMD card and 10GbE card, the other with 10GbE card, SAS card and Caldigit eSATA/USB3 card.
as far as GPU power, i think a single Titan will be fine for dailies work. upgrade to the Rocket-X when it’s released so you can get realtime on 5k content.

@Bob – i don’t believe the OP ever mentioned wanting to share media over ethernet. It sounds like he’s just putting together a DIT cart.
@Gautam – I use the R680 and have never used the Areca card, but I hear it’s great. I’ve heard that only ATTO allows LTO and hard drives on the same card. I don’t think Areca cards can do this. Go LTO6 and direct attach it so you get the speeds. Cache-A units are too slow for what you’re trying to do. as far as the eSATA fan out cable, it will work on the R680, although I’ve found it to be flaky. if you run the fan out cable or LTO, they have to be on their own port. you can’t connect a tape device to a chain with hard drives on it. I’ve not tried this with the fan out cable, but i don’t think it will work on a chain. Heat will definitely be your biggest concern, especially if you put all this in a rolling rack that will sit outside. something like this will want to be in a controlled environment otherwise components will wear out or fail completely.

very generally, a single SATA3 hard drive will deliver 150MB/s. I have a bunch of 8TB G-RAID Thunderbolt enclosures (the 2 drive versions) and they average 300MB/s. theoretically, the 4TB versions should be the same speed (until they fill up).
hope that helps

i definitely wouldn’t run RAID6 plus hot spare on an 8 drive RAID. I’m paranoid, but not that much. about half of my 8 bay RAIDs are RAID6 and half are RAID5. the more “active” ones are RAID6, but i don’t much care either way as long as there’s cold spares sitting around.
Neil, another thing you may consider is bare hard drives and a MAM system. For most of my clients, that’s a much better option than leaving everything on growing near-line RAIDs, running 24/7. But it depends on your workflow.

what features does 3.0 add? All i can find is added compatibility with Pro Tools 11.
I’m hoping 3.0 fixes the latency issues I experience with the rings in Resolve (no latency issues with other apps). But I’ve been hoping for that for a few versions now…

since no one else has responded, i’ll throw in my suggestions. 10.8.3 and 10.8.4 may some GPU driver updates that might help. also, lowering playback quality to 8 bit (but leaving rendering at 10 bit) may help.
