All camera interfaces on the Edge-2L support 4K@60fps recording.

You can find the video nodes from the table below.

Record video from CAM2:

gst-launch-1.0 v4l2src device=/dev/video31 io-mode=dmabuf min-buffers=64 num-buffers=300 ! video/x-raw,format=NV12,width=3840,height=2160,framerate=30/1 ! mpph264enc ! h264parse ! qtmux ! filesink location=/tmp/video31.mp4
