View Full Version : Acheiving Full Res-Premium - Real Time Playback

Hi all,
Just wanted to report that I've been successful at getting real time playback with the Full Res Premium setting.

When I originally built my DaVinci rig, I was very disapointed that I couldn't get real time playback with the Full Res Premium setting. I believe the bottleneck was the i/o limitations with the internal drives. There simply wasn't enough throughput. Two weeks ago, I added a Cubix Desktop 4 to the system, allowing me to attach my external raid and presto - real time playback with Full Res Premium.

Here's my setup...

PC - 2009+ Mac Pro Quad Core | 2.26 GHz | 12GB Ram
Slots: Cubix Desktop 4 Expander (RR, GTX285, ATTO H380 for LTO); Mac Pro (ATTO R380; Black Magic Extreme; GeForce; Cubix I/O)
Vid Cards: Red Rocket; GTX 285; GeForce
Drives: Sonnetech Fusion 800 (16 TB Raid 5); ATTO Express R380

Hope that helps.

You are basically asking for Red Rocket-like performance!

I don't think its possible with current era commodity hardware.

Just my 2 cents.

Maybe you should read what I wrote :) I am getting real time playback at full res.

I was planning on doing the same except swapping the rocket and decklink. Have you tried that combo?

I haven't tried that combo.
Blackmagic actually recommends having the Red Rocket in the Cubix, so that's where I placed it initially.

True, seem I didn't read it just right...
congrats.

With a RED Rocket card you weren't able to get realtime playback WITHOUT the fast RAID?

raid has nothing to do with decoding R3D...R3D is can be even on a single drive...

The drive does need to be able to feed the Rocket fast enough. If it's a usb drive for example, it'll starve rocket for frames.

But, to clarify, R3Ds are either 28, 36 or 42 MB/s. No big ask from most drives. I think the Cubix might be the key here, allowing GPU and CPU more bandwidth. Can't wait until BMD support our expander. Either way, that's freakin' cool performance from such a cheap, but powerful system.

Thank you Grant. Thank you Peter, Matt. Thanks to all the team. Keep 'em coming!

What drives do you guys use there?

What type of internal drives were you using prior to the RAID?

2tb Caviar Black setup with software Raid and a 1.5TB drive (forget which one, but similar spec) for the system drive. These are still in the system.

The hardware RAID is definitely faster, but was a (pleasant) surprise to see the difference when we were finally able to get both the faster RAID and the rocket going at the same time.

Craig is way busy right now but will probably be back on here sometime this weekend.
