Nice Vidz Guru
It looks like you could not brake enough causing the beach trip ,however it is very hard to tell with so much audio input from windnoise and so little from the engine/tires...btw I belive that brake boiling/fading should've been felt in the pedal for sure. On My Track Supra I played a lot with the location of the mics (2 camera system ,2 external mics) and I found that the best location is just next to the front left/right targe bolts.
Also track logers are huge help I just use my phone and a $5 app.
This is the output from one of my last week's laps.
As far as editing goes ,split screen ,vid in vid - Vegas Video the way to go
BTW Here is one short vid of my last week T&T sessions:
