Davinci runs slow
Hi,
I got a bit of a problem here. when i start a project, it seems it works okay (still not fast/realtime), but when i get closer to the end (mostly 3 min’s music video’s) its getting slower and slower. i understand its pretty much impossible to play RED files realtime with color correction, masks, keys and so on, but when i tweak something like only the color wheel, it updates maybe after 3/5 seconds or sometimes even longer. very annoying. i just cant work like that. Im running on a mac 2x 2.8 ghz quadcore, 16 GB DDR2 with a RED ROCKET card installed.
I tried to clean up the whole mac, updated the rocket firmware, but no noticeable effect.
i know it can never go realtime with very complex shots(at least not with this system), but im sure it shouldnt go this slow.any idea’s?
thanks in advance

What other graphic cards you have installed? Have you tried lowering the debayer quality?

i have an ATI Radeon HD 5770. i must say i didnt think about lowering the debayer quality. i will try that later today. thanks.

I think the ATI card might be your problem. Resolve is optimised for Nvidia CUDA cards and runs a hell of a lot faster on them. Not 100% sure but may be worth thinking about.

That Ati card is good for UI, not image processing. Please refer to the config guides on our support web site for details of supported configs.

Your graphics card is insufficient for Resolve. Check the configuration docs on the bmd website, but you will need an Nvidia card, not an ATI for starters. I’m not sure what fits in a macpro without expansion chassis, but I do know you can get an Nvidia GTX 570 in there and it will perform ok, much better than what you have. I think you can get a GTX 680 in, but someone else who’s done it will have to confirm.
Also make sure you have ‘use optimized playback’ enabled in settings.

Speaking of ‘use optimized playback’. Can someone tell me why anyone would want an un-optimized playback?

There is a weird thing with Cacheing that happens in optimized mode. Optimized, not so optimized for render cache.

Hi Jake,
You lose your window cursors, etc on the SDI in this mode. Only during playback.

Does anyone uses caching on Resolve? I can’t imagine anyone suffering though that…

I see, thanks for the clarification Rohit. I don’t see that as a problem, as personally, I never use cursors on the video display. Clients always complain about it. BTW, did the shortcut Shift/Cmd/C for turning the windows on/off on the video output had been taken out? I remember it used to work before, but at some point it stopped and now it is necessary to chose it from the menu.
