Thanks for your answer. I suspected that was the case, but it's nice to get it confirmed.
(Illustration just in case someone who reads this post is wondering about hither / yon and frustum):



I was wondering; would it be possible to implement the hither/yon-adjustments in a future version, or maybe as a plugin?

The obvious work-around is of course to make far-away objects smaller and place them closer to the camera,
or accept a slightly lower quality and use screen-recording to capture the video directly from the preview-window.
