red rocket and premiere cc

[Peter Garaway]

Hi Dan,

Import a .r3d file into Premiere. Right click on the file and choose Source Settings from the contextual menu. At the bottom of the Source Settings dialog you will see a Use Rocket pull down menu, select Use All Available. See image below for reference.

Thanks Peter

This has made our edit work so that is great. Thanks! It appears once you change the source for one clip it does it for the whole lot.. does that make sense to you?

I have to say the card doesn’t do as much for us as i’d hoped… it has allowed me to run at between 1/4 and 1/8 as opposed to 1/16 (with the occasional underrun) this could be my machine. please can you advise me on the settings i should use if possible?

I have a 2008
Mac Pro with mountain lion
nvidia geforce gtx 660ti (2gb ram)
hd decklink by blackmagic (4x lane) sdi output to jvc 24inch grade 2 monitor
Red rocket (x16 lane)
all hard disks are SSD
premiere cc

its possible that my internal bus speeds of my old mac are throttling me back.

i am using a red sequence at 4k. preview set to 1080p (should it be iframe or quicktime?)

we monitor through the gtx card’s 3rd dvi output or the decklink’s SDI. playback appears to be similar but slightly sharper on the deckling (adobe playback gives a deinterlaced look – probably becuase its using the system refresh rate) obviously the adobe preview has more resolution options than the blackmagic which will only allow 1/2 or 1/4

it seems odd that both solutions work,

which should i be using? is it possible to be using adobe preview to monitor whilst utilising the red rocket and CUDA engines? or even red rocket and CUDA AND the DECKLINK. seems unlikely!

my frame drop indicator is constantly green even though I am obviously dropoing frames!

two specific questions – should i able to monitor SDI from the red rocket?
why does premiere ask me to change my settings when i drag my 4k r3d onto the timeline? i.e i have a r3d timeline and when i drag my footage down (which i have imported using the correct process) onto the sequence it tells me the footage is different would i like to change if i say yes when i check the settings the codec is greyed out and labelled ‘custom’ not r3d as i would expect.

the preview setting seems to always be 1080p regardless of the fact that i am using 4k rushes.

Thanks for your help
I would love to get this sorted once and for all

best

There is allot of communication going on just between all of the cards when using the Rocket and Blackmagic besides the GPU for the acceleration. The latency of that is likely why your running into dropping frames. The CPU’s are also not ideal for this type of work to get the data down to the GPU’s very fast so that is another bottleneck. How much ram do you have in the system?

The Red Rockets can only be used for decoding/encoding outside of Cinex. You can use them fore Preview inside Cinex only.

Don’t worry about the sequence settings prompted by dropping the media if the editing resolution/aspect ration is correct. Just accept the match media prompt.

Dan…what do you mean by “preview setting” being 1080p?

Keep in mind there are a wide variety of RED settings…support for all sizes and framerates. You may have chosen the correct frame size, but what about framerate? What are the spec on the clips you’re importing? There are 23.976 and 24 fps specifications, and Premiere Pro (rightly so) does not consider them to be the same thing. So…even a framerate incompatibility between the media and the timeline will cause that warning to come up.

You want to verify which framerate is the correct one for your project…if some portion of the raw footage was created using the wrong framerate, you don’t necessarily want to conform your whole edit to it.

The “custom” thing is Adobe’s typical timeline conform designation if it can’t match a preset… If there is a compatible preset, it chooses it alphabetically believe it or not…if you conform something to 1080p media, it used to always say it was “AVC-Intra”…now it says it’s “ARRI” since it was added and now comes before AVC-Intra in the alphabet. For 1080i, it will still say AVC-Intra…whatever is the first compatible preset in the list alphabetically…simplification that actually adds confusion.

This is confusing for new users who don’t realize that Premiere Pro specifies a sequence with three items…frame rate, frame size (pixel dimensions), and pixel shape or PAR (square, non-square, etc). Since Premiere Pro is codec-agnostic. The basic settings of a 1920x1080p23.976 sequence are fundamentally the same whether it’s an AVCHD, or DSLR, or XDcamHD422, or whatever the format name is (other than the settings you can modify like the preview format, timecode, etc which can be different or user-defined)

The codec itself doesn’t matter…if it’s on the machine, PPro uses it.

The key time these sequence settings matter is in the case of codecs that can be used for “smart rendering”…so if you want a DNxHD (among others…) sequence that preview renders in DNxHD and then you can export DNxHD very quickly by skipping re-compression when the parameters are consistent.

Thanks Eric
It all seems to work ok I think our mac is just too old – I hear what you are saying about latency.

I thought that the red card would give me realtime previewing in premiere, but as you say this is not the case. I hope its not a silly question, but why do you think the card is limited to only encoding/decoding in premiere? it seems a shame to have realitime playback in cinex but not in the edit space using the same footage. it guess its because premiere doesn’t run from the rocket its processing isnt in redcode its in cuda or open_cl? – hence what you were saying about latency comes into effect?

thanks for your help anyway

Best

thanks Tim

by ‘preview setting’ i mean the video previews setting of the timeline. it seems to be at 1080p, just seems odd that premiere would assume this resolution given i told it my footage is 4k. maybe its the closest match to my desktop resolution which is 1920×1200?

I my footage is 30fps from a 25fps base. we shot this for aesthetic reasons. maybe premiere is confused by my selecting 4k25, when my footage is playing back at 30?

thanks for your help
