I recently purchased a couple DATAQ instruments devices for some testing I'm doing on my electric snow cat. You can log all sorts of stuff simultaneously; for example, I measured current and voltage supplied to a pair of DC motors. I'm not the most patient person for getting software running, but their free software worked great with little futzing around. 
For example, the DI-149 allows up to 8 analog input channels +/-150V. The instrument plugs into a USB port and runs with windoze software. I think between your videos and some synchronized direct data gathering, you'd have an unbeatable combo.

Hmm. Is this what you are describing?
DI-149 USB Data Acquisition Starter Kit
What I get from the description is that it will read +/- 10V but will withstand +/- 150V for a short period or +/- 75V continuous. Or am I looking at some old data?
