TIL: if you have a laptop with multiple gpus, and its set in eco mode, the steam video exporter wont let you export to h.265/hevc because it exclusively uses the high end gpu for that. ghelper on the asus rog laptops is great, but if you have it set to eco mode, the nvidia gpu is 'just off', and even the nvidia installer will complain there is no gpu present. seems like none of these apps talk to eachother and it seems to make for a kinda dumb ux.
