GES is not rotating a *.mov file which is tagged for rotation

GES should do it automatically since
https://gitlab.freedesktop.org/gstreamer/gst-editing-services/commit/77dac21488f2217c9fc0cb7a7bfba1f5c0ef8789
can check if that works:
gst-launch-1.0 uridecodebin uri=file://your/file.move ! videoflip !
video-direction=auto ! videoconvert ! autovideosink
