If you can find a suitable cube LUT, for converting rec 2020 to rec 709, you could use my 'color grading' shader (TROIKATRONIX : ISADORA - DX – PY – Cube2LUT – ColorGrading).

This should allow you to convert the color, but will not be as true to source as making the conversion in something like Davinci Resolve (my recommended option).

I have a video camera that I will turn on its side to capture in portrait (vertical) orientation.

I will feed that into Isadora via HDMI capture. The image will be HD (1920 x 1080) and in landscape orientation.
So I need to rotate that image 90 degrees so that it matches the orientation of the camera. I will use this image across lots of scenes.

I thought I would go:

video in watcher to projector to a virtual stage. Make the virtual stage 1080 x 1920 pxSpin the projector 90 degreesUse Get Stage Image of virtual stage to bring the rotated image in the correct orientation into my scenes.

However, my camera input on the virtual stage does not fill that 1080 x 1920 px stage: I have to zoom in to 175% on the virtual stage's projector to make it do so.
I think this is affecting the image quality.

I tried this:

video in watcher to projector to a virtual stage. Make the virtual stage 1080 x 1920 pxSpin the projector 90 degrees.In the projector turn OFF keep aspectchange height to 55% and width to 178Use Get Stage Image of virtual stage to bring the rotated image in the correct orientation into my scenes.

So this works better, but is this having an effect on image quality too? 

OR am I missing something very, very obvious?!

Here's the  project file for anyone curious...
