I"LL SEND YOU $5 BUCKS FOR A SOLUTION!

I have a 5k feature project that is bogging down my system. I have an older Mac Pro.
My client wants the ability to export the Colored media at any size he chooses.

In order to free up GPU memory so my system can handle the work i had to bring down the RED media to "Half res Good" and turn on the proxies setting (1920X1080). Now i can grade, color and save stills without errors.

But when i bumped the project back 5k by turing off the proxies setting. My power windows shrink. Or stay the same size, however you look at it. They are now scaled totally wrong. The same thing happens when i change the master project settings.
Is this normal?

I thought Resolve was scalable and could figure this out. I don't see the point of the proxy setting if my masks can't jump back and forth.

If i can't work this way, is there another suggestion to work on this project?
Any help is very appreciated. Thanks you!

I have not experienced this personally but have you tried to grab a still switch resolutions then re-apply the still? (Not the best solution but worth a try) Is it for specific clips or all clips or grouped clips. Are you adjusting just the clip or are you adjusting the timeline?

My guess is you need to change your setting under Project Settings > Image Scaling > Input Scaling Preset.

For the GPU issue, it would be helpful to know your system hardware and software details.

Regarding proxy mode and window scaling, how are you using proxy mode? What do you mean by "proxies setting (1920x1080)"?

All media is on an external USB 3.0 6TB drive.
I assume the GPU error message is because of my graphics card isn't cutting it at this resolution. Also besides the message my frame looks like scrabbled colored noise.


Robert- i have that input set to the first selection "center crop no resizing" That might work but I'm testing some things.

I believe the Input Scaling Preset should have been set to Scale entire image to fit.

For additional performance, you might also try reducing your timeline resolution to 1920x1013. Otherwise, you're just upscaling your HD proxy to 5k and then downscaling it back to HD. You could just turn off the proxy and leave the timeline at 1920x1013 (with scale entire image to fit). When your're ready to render, switch the timeline to 5k.

No "input output settings change" will allow a Power window made with proxy mode "on" (at a different size) to rescale to the size of the project when you render or turn off Proxy settings check box.

Start a 5k RED project and turn on proxy at 1920X1080 and give it a try. It won't work on my machine.

Looks like I'm screwed unless there is anything that can be done to increase GPU performance so i can work at "half res good" without the GPU error message.

I don't think there's a way to salvage your current settings. I would stay away from proxy mode. I'd set the timeline to 1920x1013, Input Scaling Preset to Scale entire image, and Output Scaling Preset to Match timeline. Temporarily setting the scaling to bilinear might give you an extra 1 -2 frames per sec as well. Then set the timeline to 5k when ready to render.

You could also set the cache to cache the source on each clip. Do you still get a GPU error with these settings?

Using your settings, I do not have window size changes when I toggle proxy mode on and off.

So I guess we would need a project export .drp from you to tell what's really going on with that.

But it's sort of a moot point, because you are not going to be able to render anything at that timeline resolution with a GTX285 card.

And as Kelly mentions, the normal workflow for most people in this scenario (assuming you had a GPU with enough VRAM to render out at 5K, if that's your end goal) would be to simply use an HD timeline, for much better performance, and then set the timeline to your render resolution when it's time to render.

Thank you for the feedback.

Kelly- if i use a timeline with 1920x1013 and create any power windows when i change the timeline back to 5k to render the windows "shrink"

Thanks you Dwaine, I'm not trying to render out on this machine just color. I'm yogin to transfer the project to new mac when its time to render.
I will upload a .drp so you can see how my power windows are reacting to proxy and timeline changes.


I found a "work around" so i can at least color right now. I found that a 3k timeline runs on the system without GPU error. I'm currently coloring now in that timeline. If the client wants to render out 5k i will have to (if there is still no fix found) change the timeline to 5K on the render machine and QC all my work with power windows and make the adjustments to their scale. Because it's only going from 3k-5k they won't be as far off as a 1920X1080 timeline.

Can someone answer me this? If you change timeline resolution, do your power windows hold exact position?

Also, USB 3.0 is not going to be fast enough to handle 5K files (in my opinion).

What aspect ratio is 1920x1013 for the proxies? That's a new one on me.

Changing Timeline Resolution is supposed to automatically change window position and keep them in the right relative place, but I have seen rare cases where it screwed up. Not often, and not recently.

Hey Marc, Thanks for the answer. Seems like I'm getting the "rare case" here. I hope there is a fix.

The DP setup the project and when i tried to apply 1920x1080 proxy it changed automatically to 1013. His default timeline is 5120X2700.

would be to simply use an HD timeline, for much better performance, and then set the timeline to your render resolution when it's time to render.

Well I dont know if I understand this correctly but... I usually go for HD timeline and when its time to render I just use "render using source res" (truth is I usually combine more input res so thats the only way).

As far as proxies are concerned I wouldnt use proxies with red at all :-O I am working with 1/8 or eve 1/16 when I need to. The usuall settings wont allow you to go lower than 1/4 but when you go to media tab you can select all r3ds and hit right button and Red decoder settings or somethin like that and use whatever you want. Then for color grading I would use like 1/2 or full and for render make sure I hit force debayer and force size....

But maybe what I just typed in is a nonsence and you were asking a totaly different question not sure...

I'd just go buy a 4GB or larger GPU. It will pay for itself almost instantly.

The only option with your GTX 285 is:

1. Stick to 1920x1080 timeline and all your project settings.
2. Come to deliver page. Set output to required 5K.
3. Tick the "force sizing to highest quality" and "force debayer to highest quality" boxes.

Render out in 5K. This is not ideal, but usable. It will take a looooong time to render out though!

[Dwaine Maggart]

That likely will not work. The GTX285 does not have enough VRAM to make that work. But you can certainly try it and see.
