Neat, I was looking for such a tool a few days back and ended up not having the requisite google skills to find this (embarrassingly, it seems easy it find now)

I ended up writing my own script for visualizing my particular problem (trying to work out what's going on in the "mett" data frames in videos from my pixel phone, I was able to make some headway but I've gotten distracted by other projects, if anyone has info I'd appreciate it)
