RCX not taking advantage of hardware...

[Brandon Fraley]

When either playing back clips or transcoding, RCX is only pushing the processors about 50% and I just upgraded my ram from 4 gigs to 16, and it's not using any more of it than it had before.

Any ideas on how to get the software to take advantage of the hardware?

THANKS!

REDCine-X is not multicore optimized. My guess is that takes a whole lot of programming and they are more relying on the RED rocket.

For transcoding:

Before RR, I used to use the redline terminal.
RCX is offering to output the encode into batch scripts, which makes it easier now.

I found that if I run one terminal redline it uses 2 cores to max.
Ergo 4 terminals for an 8-core for example.

This should guarantee you 780% - 790% processor usage.

I used to run it on 5 mac pro's at once for a core melt.
Now trying to do the same with RR... :-D

As always we are working to improve multicore support. As far as memory goes, RCX will most definitely take advantage of it if there. Make sure you are using a 64 bit build and have set your Maximum Memory Usage (Preferences -> Playback) all the way up to 100%.

David - what about GPU/CUDA support with REDCINE-X and the API used by Fusion, Premiere, etc. to debayer?

I know it might initially feel to you like it would cannibalize your ROCKET card and reduce revenue - but it would make the cost of entry lower for Scarlet and Epic users.

Once you get them into a RED camera rather than a competing product, you'll have them for life for all the other RED accessories and additions.

If their perception is that you need a rocket to use R3D files, this will cut your market regardless of the reality. Having CUDA support would certainly blunt Boom's articles and comments.

The studios will always buy 5 ROCKETS anyway for their workstations and want better-than-real-time, but ... not everyone can afford that.

I don't have another PCIe slot available, so even if I came up with the cash (not really an option, the Scarlet is going to tap me out), I'm out of luck.

Whatever makes the initial decision to buy a Scarlet or Epic easier, will end up making you money in the long run.

Thanks.

Both are not true

Les: thanks for the feedback. We understand what you want, and we're always looking at available and emerging technologies.

Brandon, By using hardware acceleration such as GPU and/or Red Rocket the software actually uses LESS CPU and/or less RAM. Trust me, you do not want any software use anywhere near 100% of the CPU or the memory.

Performance tuning, concurrent processing, memory management, etc are much more complex than what laymen think. Most programmers don't understand it either, but that's a different issue

A simple question about RedCine:

Will it run 4K files smoother on a 2 cpu x4 cores - or on a 4 cpu x2 cores workstation.
In other words would RedCine take more advantage from a multiprocessor with less cores or from a multycore and less CPUs? (given the same number of total cores)

Same question applies to Da Vinci.

Does anybody happen to know some facts on this?
