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.
