How do you get trackmaster to overlay on your video? I picked up a bluetooth OBDII reader a few weeks ago and have some datalogging software for my android phone that that records accellerometer data, GPS and a number of OBDII stuff (throttle position, rpm, MAF, O2 sensors, engine load, fuel settings, etc.). I haven't found any good way to get that over my in-car video, though. More a nice-to-have; I think the real serious analysis will be when I overlay my runs and my codriver's runs in excel and figure out where each of us has room to improve.

sjfehr,
Trackmaster allows you to export video data (hold down on one of your sessions in the Sessions screen) and plug that data into another app (I used RACE2AVI or whatever it's called).
Their site has all the details: http://trackmaster.trackaroo.com/welcome

Turns out trackmaster (and my the other two datalogging programs I have) only update GPS at 1Hz due to limitations of GPS on Android phones, which makes it rather useless for autocross without a separate bluetooth GPS
The accelerometer data is still very useful, though. What software do you use to integrate your various video feeds?

Yep. I had the same issue. I ended up buying a $45 external bluetooth GPS unit...recomended by Trackmaster.
I use Sony Vegas Movie Studio HD ($35) to produce the video.

We had our first autocross of the year today, and it marked my first race on r-comps! (I ran the last 3 seasons on street tires.) I was entirely unprepared for how slippery they were in the cold (40s), and presumably still with mold release on my first two runs. This was my 4th and fastest for the day. Was good enough to hold pax ftd for the heat, so I did OK with that respect, but I was passed by faster drivers later in the day.

No fancy embedded telemetry yet this race

Today was my 2nd autocross on r-comps (still at Pungo), this time with the local SCCA and with much better weather. Finished 2nd overall, a mere 2 tenths out of first, which I'm thrilled with. Maybe next time I'll find those missing tenths!

Nice run. I think you lost the tenths in the slow 180 near the end. The slower you go the more important it is to keep a tight line and not waste distance. Other than that the run looked great. How do you like R tires? Really addictive. Wait until you get to a smoother bigger lot than Pungo and the temps warm up. Then you will see why we call them black crack.
That looked like a nice course. The best I have seen there.

We lost ACU4 this year (new base CO kicked all the civilian groups off), so it's all Pungo for now locally, unfortunately. I liked the feel and the extra grip of the V710s (and my wife REALLY likes the feel of them) and I liked that I finally got a fair pax time that I could consider competitively with everyone else in the club, but I had just as much fun on street tires. If they ever let me into STR I might grab some camber plates and springs and jump back on the street tire bandwagon. Maybe my opinion will change on a more open course, I dunno. I do know my in-car video looks impossibly fast, lol... I keep telling people I didn't even have to change the way I drive- just that the tires finally caught up with my aggressiveness! I've still got a long ways to go for improving as a driver, though.
Some telemetry from my codriver and I (1Hz OBDII/GPS data rate, unfortunately, and a lot of noise in the 10Hz accelerometer):
