iPad’s lightning/usb-c connection to Mac Like shown …
import each source to new separate layers …
or place in media bin…
After connected you can choose any app…
like drawing, photos, videos, Facetime
Take care of cropping top and bottom
of the layer a bit to hide device infos … ;)
rotation lock of the captured device
should be “active“ in landscape mode,
because input will rotate like on your device…
