Nice overtake on the yellow truck Rupe.
The music choices are very limited on youtube editor but that was not so bad. You could do a fast forward onboard with that kind of music.
Consider recording at 720p to get better frame rate; 1080p is nice but most people watch within the web browser at 720p.
Maybe have a go at camera switching on the fly whilst recoding.
TIP: Use external car cam between TV Cam and Cockpit Cam.
TIP2: Use can use the look behind button on your wheel when the car cam
is on your car or anothers.
TIP3: Consider some live fraps recording (maybe just the lights with driver name tags at the start). I have done some live fraps recording whilst parked on the grass but one driver thought that was not considerate to people racing so I will not do that again but cockpit live recording is cool.
TIP4: Use virtualdub (virtualdub.org) for pre editing before youtube editor.
