  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Let's say you have a 4k R3D and a 2k project in Resolve.

If you scale the R3D to 150% does it use the fantastic extra resolution of the R3D or does it first down res to 2K and then scale it back up?

Obviously a big difference in how much you can scale.
 
If your template is set to 4k and your output format is set to 2k, then I would think any resizing done on the input side will use the full 4k since there's no initial scaling.
If your template is set to 2k and you're doing resizing, then I'm not sure. I would imagine it'd only have 2k to work unless Resolve concatenates the template resize and the input resize, which is possible but I don't know for sure.
 
i would assume it uses whatever resolution it has, and aggregates for the project size.

it would take more time to scale twice than just once, so i don't think they'd be doing that as there are no benefits.
 
It depends on the output resolution and debayer quality. If you use full quality debayer on a hd or 2k timeline, you can push in about 200% and the results would be similar to shooting in the red at 2k where it crops in on the sensor. The workflow I use without a redrocket is to color at 1/4 good, doing all my repo's and whatnot that way, at the end I render everything at full premium. You can evaluate the quality of the image if you enable cache on the clip in full premium as well, otherwise in 1/4 good, you are going to see a fairly low res image.
 
Resolve, unlike some other systems, doesn't use an intermediate codec for debayer. All debayer is done "live". So, if you set your render to full quality debayer and your project is set to 2k, scaling up still will use full 4k size. But, if you render 2k and then decide to do the blow up, then you will be limited to rendered size-2k.
 
Jake is right, i've done tests where i set my timeline to 4k, and scaled in 20%, and rendered out as 1080p. did the same with a 1080p timeline with same clip. set them to full debayer, identical results. you are always working with 4K files if you are working with r3d. so doing pan and scan, crops, reframing with r3d's in whatever resolution timeline, you'll always be working with the highest resolution files. i'm sure the same applies with other types of files too.
