Vertical Video - makes my head hurt

mark_m

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 px
Spin the projector 90 degrees
Use 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 px
Spin the projector 90 degrees.
In the projector turn OFF keep aspect
change height to 55% and width to 178
Use 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...
