The Samsung 13MP image sensor in the Librem 5 is capable of capturing 4K video at 30fps, but the i.MX 8M Quad has no hardware video encoder and its documentation indicates that it is only capable of encoding 1080p video at 30fps in software. There is currently no kernel support for the [front](https://source.puri.sm/Librem5/linux-next/-/issues/44) and [back](https://source.puri.sm/Librem5/linux-next/-/issues/43) cameras and there is only a [mockup](https://gitlab.gnome.org/Teams/Design/app-mockups/commit/91830ed0c2929bec14a05792db5ab3629afe6f46) of a [future camara app](https://www.omgubuntu.co.uk/2020/02/gnome-camera-app-mockup) for the Librem 5.
