  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Just got the rocket today....cool looking box! Unfortunately thats all I can say for it right now.

I have a Macpro Tower 2.66 dual core
5gigs of ram
I have it in the 8xpci lane
3 tb in raid config.

right now its taking like 3min to render out a 40sec clip in Prores 444.

What do I need to speed this thing up? I know its user error!
Thanks
 
You didn't say what software you are using. The Rocket only works with Red Cine X and Rocket Cine X, and you need to make sure you select the Rocket icon and it's glowing.

Also, you didn't say what resolution you are transcoding to.

Let us know what's happening and we can help. You should be getting 1:1 or at worst 1:1.5, but 1:4 sounds like there is no Rocket at all.

Sorry I am using Red Cine X 221 I think the most recent. Full Debayer Prores 444. I can see the rocket icon glowing.
 
What resolution are you transcoding to? Makes a big difference in transcode time.

Also, do you get realtime playback of your R3Ds? This is the big test.
 
Also, is your rocket installed in slot 2? I recall a lot of discussion on what slot and therefore i placed mine in 2nd slot.

I do transcodes pretty regular from R3D to prores 4444 and get about 1:1.5 speed....BUT at 1920 x 1080. This will make a difference if you set your size higher.
 
Im going to 1920x1080 and at full res the r3d's choke a little bit.
 
what slot is your card in?
sounds strange since i can get smoking speeds with this setup. I think you should also up your ram to 8gig to 16gig. Mine is an older 2.2ghz machine with 32gig ram, but i think i'm only utilizing 16gig.
But slot two is best place and there have been all kinds of reported problems if using anything else.

How does your performance in RedCineX b221 compare to RocketCineX b1740?

I do notice that transcodes seem to be a bit faster under RocketCineX compared to RedCineX though playback performance is about the same.

I wonder if this is due to the Quicktime encoding part of the transcode as RocketCineX seems to make better use of more CPU cores compared to RedCineX.
I imagine this is due to RedCineX not being fully optimized in Beta.

My card happens to be in slot 2.

Ok, Rocket Cine is way faster a clip that is 30 sec took 1:15 in redcine took only 35 sec. in Rocket cine!!! Oh yeah im in slot 2!!

Yeah, I think when RedCineX is fully optimized it should be similar to RocketCine X in speed.

I still like what's going on in RedCine X developments
and have been using it for the past week to "pre-grade" a film. It's really grown and it's quite stable.

Enjoy your RedRocket!

Can you send us the logs for both?

We're testing redcinex to be faster than rocketcine for most things.

Please email to redcinex@red dot com
 
Hey Deanan, why can't RedCineX be the same if not faster and better than the "not being developed" RocketCineX?

It is faster or the same depending on the format being output. At least according to our internal testing. If someone is seeing something different, it could be related to disk/cpu/os differences but we'd need to replicate to find out why.

Redcinex now uses a separate exporter thread for dnx and quicktime so it's also more stable because quicktime used to hog all the memory.
 
What the heck am I doing wrong? I was pretty used to 1-1.5x realtime speeds going to to Pro Res, but I am getting non RR speeds today of 20-25x realtime with some 2K/3K footage going to 1080 Pro Res. Build 1740 in my mac pro 8 core 2.93 in slot 2.
 
I am having the same issue. I am cooking 4hr 18min of footage, I am curently 6 hours in to it and it has done only one third of it. It was shot 4kHD, 29.97 transcoding to ProRes HQ 29.97 with RCX221. It is cooking in a basic color correction. It is not stalled or hung up it is constantly progressing.

It seems long to me. Dose this sound right to you guys?

Any Tips? Restart it?

Thx,
Rich
 
I solved the issue with my footage but it doesn't apply to your situation. My footage was 2K 2:1 which is 2048x1024 and I was trying transcode to 1920x1080. The jump from 1024 height to 1080 height is technically upscaling and that cannot use the rocket, so my speeds were processor.

On all my shoots where the DIT has a rocket ,redcinex performs at 2x to 3x realtime, whereas rocketcine is almost 1x realtime. This is several dits with rockets on different systems. Transcoding 4khd to 1920x1080 prores422 or dnxhd175 23.98. Ive NEVER experienced redcinex transocde at realtime. Such a bummer.

Thats basically what I am experiencing.

Thanks,

I benchmarked a little slower than 1.5x via RocketCine, but this was before I upgraded my RAM from 6G to 12G, and before I RAIDed my 4 internal drives. Also, source footage location was from a 5400 rpm LaCie rugged drive over FW800.

I've got some more testing to do obviously, and I can't recall in which slot I've got the rocket installed, but will look into that too ~ I was unaware of any performance issues with slot selection.
