So - for starters, I can't find ANYTHING that's Stereo, closest thing I can find appears to be StroBMX:

The 48spline Profile (and copy) cranks are generally not threaded for a puller. I saw you tried the socket and hammer suggestion at BMXMuseum. Looking at your video - you need to brace the frame closer to the bottom bracket on something hard, not a cushioned chair. The frame is moving a lot and the chair is absorbing all the energy you want to go into the spindle. Put the main triangle on a work table edge , as close as you can get to the bottom bracket and use the same socket. Don't use the extension - it's not doing anything except absorbing more energy. Just hit the back of the socket.

If that doesn't work, heat the crank arm (not spindle) with a torch. It'll ruin your finish, but should get it off.
