Red Epic Scaling
Hi All,
Correcting some 5K Red Epic footage down to a 1080p timeline. When scaling and re-positioning 5K shots using the format tab, what is the optimum way of doing this. By default the scale factor on both input and output is 1.0 and I am not certain where the best place within Resolve to apply the transformation. Would the best place be in the config tab > Center Crop No Resizing? Then reduce the default scale in the Primaries from 1.0 to say .5?
Thanks for helping a new DaVinci & Epic User

The nice thing is that DaVinci will do the optimal scaling for you… so if you take 5K into an HD project and scale it up, you won’t lose quality. You will, however, lose quality if you have your source decoder settings set to half-res, quarter-res, eighth etc. The best thing to do is use “full-res premium” when rendering.
I find it easiest to keep the default “scale to fit” and then scale in the format > input tab. You will still get the highest quality (if your decoder settings are high) and the framing won’t change when you change the decoder settings (which I think happens if “center crop” is chosen).

Hi Kevin,
Thanks for the information. I still have a bit of confusion on this. Let me explain The Epic resolution is 5120 x 2700 as displayed by DaVinci details. Project is set up to 1080p. When I click on a clip in the timeline and then go to the format tab, the zoom range is .250 to 4 and seems to be working as expected. But if I right click on the viewer in the top right of the DaVinci interface and select “show actual size” it seems as though there is much more image to zoom in on. I am used to seeing a wireframe outline of the full raster in other programs and that aids in determining how I am repo-ing the shot. Right now I am not 100% sure the math thats going on. One thing I really want to know is how I can determine if I am scaling larger than 100%
Thanks

Try enabling “gray viewer background” in the settings… this might help because the viewer background will appear gray, and your 16×9 frame will appear as black or with picture.
Zooming the viewer doesn’t change any of the scaling, so “actual size” probably just zooms the viewer so pixels appear 1:1. But you would want to zoom out until you see all the frame edges (and with the gray background there’s no confusion about the frame edges.
