As far as I'm aware you still have to do it via 3Speak.

_{non-zero chance PeakD might not want to deal with the storage and processing involved with video so it might not be a thing on the radar}

I'm waiting to see if they'll support video tags (which is all I need and they've generally been pretty good at just putting things in that I've wanted at some point without me having to do anything XD) or whether I'm going to have to brave going to one of their channels to request it/find out why they won't if it's a thing they don't want to do.

Meanwhile this is such a poster shot.
