I usually get renders of 29 or 30 with 5 or 6 nodes with prores originated material, I’m using an internal raid with 3 disks.
While grading I’ve not encountered problems with playback speed during real sessions using HD prores material. Sometimes the clip starts playing at 23 fps but after one second or so goes up to 25 fps and stays there, even with fairly complex grades of 8 to 10 nodes and with a few blurred qualifiers.Jorge Torrens

I’m using a flashed for Mac gtx 260 plus a 120 to drive the monitors in a 2010 2,66 ghz 12 procs, and it’s working really well. I bought the 260 while waiting for the fx4000 to came out as a cheaper alternative to the 285, but At the moment I’m sticking with the 260 as is working fine for my line of work, episodic TV shot in HD plus some Red work.

[Rohit Gupta] “Prev Clip (ALT: First Frame)
Next Clip (ALT: Last Frame)”Have you consider changing Next Clip (ALT: Last Frame) to Next Clip (ALT: Middle Frame)? I find myself very often going to the middle of the clip for grading, and moving to the last frame of the clip is very fast with Next Clip followed by ALT Play Fwd

I didn’t know that one, just tried and it’s a real time saver, is there any documentation for the mapping in the wave panel?

They have also map a ton of new options to the wave panel, so many that for same options is faster for me to use my wacom than to get to the relevant function on the wave.
Time to start thinking on buying the Resolve Panels 🙂

Hi Sean, i built the system myself, everything is standard exceptfor the 265 that I bought flashed for mac from eBay.
I do mostly broadcast work, at the moment I am grading a sitcom that starts tomorrow in the spanish tv. In fact the first two episodes are graded in Color and I changed halfway to Resolve, never used it before but I found it pretty easy to pick-up, I had some problems with the conform, not as transparent as sending an XML from Fcp to Color. -
News from Aja, I have just received a mail from Rudy in Aja technical support telling me that engineering in Aja has replicated my problem and there will be a driver fix in the next couple of weeks.
So I will use the adjusted black level in the mean time and see what happens with the new drivers.
Thank you very much Gary and Jeremy for the time that you have spent looking into it, and for me it has been a very informative conversation, and also thank you Aja for a very good and prompt technical support.

Ok, so what you mean is that although the IoExpress does not see a RGB image from Nuke the Dreamcolor assumes that because the signal is coming from HDMI it should be RGB?

[Jeremy Garchow]That’s a rather broad assumption. The purpose of the calibration is to calibrate the material to your output. Also, DVI is 8 bit, and HDMI 1.3 is 10bit. The HDP2 and ioExpress can both output true 10bit HDMI 1.3a signals
Yes, but shouldn’t the levels of all the outputs been the same, leaving aside the difference between 8bits and 10bits, or in other words if I were to monitor the diferent outputs in a waveform monitor I should not see any difference, shouldn’t I?, If it were the case then I should not have to recalibrate my monitor when changing the outputs in the card.
The blackmagic outputs 8bits, but it also works with both HDMI and DVI, is equivalent to the HDP2 with the very important difference of not supporting HDMI 1.3, the reason why I changed to Aja after years of using blackmagic products.

[Jorge Torrens] “but then how it is posible that the Dreamcolor sees the image as RGB, otherwise it would not allow to select a colorspace?”The ioExpress is outputting RGB.
I was refering to what Gary said about the IoExpress not being able to output RGB at the moment from animation packages as Nuke, or at least this is what I understood.Thanks again

Hi Gary
[gary adcock]OK – the IoX does not support RGB video out- so something is doing the conversion from your Nuke file to YUV- it is NOT the hardware.
Good to know, then it must be nuke the one doing the conversion to YUV, but then how it is posible that the Dreamcolor sees the image as RGB, otherwise it would not allow to select a colorspace?
[gary adcock]Isn’t that what calibrating a monitor is??- adjusting it so that the viewing space is a close to correct as possible? Correct calibration of BroadcastVideo monitors is done using the “blue only settings” while viewing 75% SMPTE Color bars.
I meant having the monitor calibrated by the probe as opose to manually calibrating using bars and blue only settings. But as Jeremy points out in his last post, it is posible to have the colorimetry of the monitor calibrated by the probe and then modify the black levels in the dreamcolor without modifing the relationship between the colors or the contrast.
I guess what made me uncomfortable was the fact that if I had the monitor calibrated before and the different outputs from the IoExpress as well as the ones from the blackmagic should be outputting the same levels, then why should I have to adjust the black level of the monitor when changing from one output to another.
Sorry again Gary for the trouble, this threat is getting very long and I’m feeling guilty of wasting your time and Jeremy’s in a problem that is quite particular to my workflow.
