How to rotate videos (and retain quality)?

You could try doing it in OpenShot.  I do not know about loss of quality,
but here is what the manual says:

Rotate Effect

    * OpenShot Video Editor Manual – v1.2.0

If you need to rotate a clip 90 degrees, 180 degrees, or even animate the
rotation around in circles, OpenShot has a Rotate effect which can help.

OpenShot has two types of rotation effects available, fixed and animated.
To apply a rotation effect, switch to the Effects Tab on the main window,
and drag the Rotate effect onto your clip.

To adjust your rotation settings, right-click on the clip and choose
Properties.  Then switch to the Effects tab on the properties window, and
click on the Rotate effect.  This will bring up a list of rotation settings
that can be adjusted.  Try changing each setting, and use the Play Button to
preview the effect.

    * 16.1. Fixed Rotation
    * 16.2. Animated Rotation

16.1. Fixed Rotation

A fixed rotation can rotate a video 90 degrees, 180 degrees, or any number
of degrees you need.  It does not animate the rotation.  This is useful when
you record a video sideways, and need to rotate it.  To use a fixed
rotation, only adjust the settings with that start with “Fixed”.  Be sure to
adjust the other settings back to zero.
