RT Performance

Frankly, I think a new Mac Pro is what you want… 12 core gallore.
I mean, you are asking for double the encoding power when setting it to 60 fps.
On the other hand, FCP is happy to play 2-3 streams of 25p on my system.

I think roman is saying 1080i60 (59.94) not 1080p60 so a frame rate of 29.97. Right Roman?

1080i60 ProRes accounts for 90% of the work I do and I get solid playback no problem on both single and dual GPU systems. Both GTX285s.. What slots do you have your cards in?

Right I’m talking about 60i.
Since posting I discovered some of the footage in the source sequence was XDcam and some was prores(HQ). Also I can’t be sure that that my shared storage isn’t a factor in the problem. When I had a moment I did a little test where I transcoded some of the source sequence to prores(HQ) to my internal stripe (instead of shared storage) and that seemed to play back correctly when I created a default session in Resolve. I’ll test more when I get a chance. Thanks for the responses!

yeah disk access can have a huge impact. Have you run either the BM or AJA disk test utility to see what kind of read/writes your getting on the shared storage?

But still if disk io is not bottleneck then machine probably is as prorez eats up cpu a lot.

hey i am pretty new to resolve and i want to know what settings do i use to import 720 60p clips from fcp via edl. i have been battling with this for the longest time and fear i will have to rely on apple color for my grading.

[Roman Hankewycz]

What are the issues you’re having?
The basic workflow is:
(1) export EDL from FCP.
(2) load the footage used in the piece into the media pool in Resolve.
(3) import the EDL in Resolve
(4) clear up any conflicts with the conformed session in Resolve.

Give some info on your project like what are the specs for your offline sequence, what format are you finishing to, etc.

I have been using that workflow for my 24 frame clips. However when i try to follow the same workflow with my 720 60p clips, they are blank in the resolve conformed timeline. The only way i get the conformed edl to work is to convert my clips to 24 frames in cinema tool, then go into clip settings in fcp to change the tc rate from 60 to 24, export the edl then conform in davinci.
I would like to be able to grade a mixed timeline but i don’t see how to do that with resolve 7. I fear all my clips will have to be converted to 24, i time consuming process i was hoping to avoid as i have to change all my clips tc rate from 60 to 24 frames individually.
If you know a work flow that i can use i would love to know. i have posted my questions on fxphd and been waiting for days for a response.

I don’t see what the problem could be. If your footage is 59.94, and your sequence is 59.94 and you send an EDL to Resolve it should come through. Same thing with 23.98 footage in a 23.98 timeline.
However, I’m guessing that your talking about 59.94 footage in a 23.98 sequence which is definitely a problem. As of now, Resolve doesn’t work with mixed frame rates (frame size is not a problem but frame rate is).
Before you go to Resolve you have to make sure that the clips in your timeline match your sequence in frame rate. That unfortunately means removing pull down, or transcoding source media; sometimes manually. If you don’t do this, Resolve will link to the wrong part of the media, at least that’s my experience.
