Data Overlay on Track Videos
Just looking to see what everyone else is using for overlaying data collected from a logger like the Aim Solo onto a video.
I know there is TrackVision, Dashware and RaceRender but wasn't sure of any others and also looking to get your thoughts on how well you like the software.

Racerender is pretty awesome with the various styles and gauges. It's very easy to edit and sync as well. There are an infinite number of possible combinations. It can be a bit cumbersome with really high definition video though.

Alright. I'm going to admit I don't understand how this overlay stuff works. I have a Droid Razor phone and a GoPro Hero 2 camera. So, I download the app for the track application? Then I buy a GPS corresponder, correct?
But how do you sync the the camera to the phone? Does it plug into it?
Also, when I get home and download my GoPro footage to my computer. How do you then get the Droid footage onto the computer?
Is there a good how-to to read somewhere?

Jeremy,
You sync them in RaceRender. At the track, start the camera when you go out and run Trackmaster normally. When you get home, use the Export for Video option in Trackmaster to create a file that RaceRender can read. Getting the data and video in sync can be a PITA sometimes.
To run Trackmaster on your phone, you will need the Trackmaster app as well as the Bluetooth GPS Service. For the external GPS, I use a and set it to 5Hz. You can use the phone's native GPS but it's only 1Hz and had trouble keeping up.

trackmaster is a good app but gps data only; speed, g-force, track map and location, etc. Does not integrate with car data via ODBII. I would really like that to get tach, throttle, brake etc.
you can add an external GPS to get higher sampling rate. internal phone is limited to 1Hz. It works ... just do that first few times till you get used to it.
You log a session, go into that session in the trackmaster aapp and select Video Data. It saves a .xls file to the phone's storage. Transfer that file and your video file to your PC. Run racerender, import both of those files into a project, sync them (set the starting video time to when you cross the first split marker on the track map which is where the trackmaster app starts recording gps data), arrange your widgets on the video screen (speedo, track map, lap time etc), export to a video file like .wmv, and you are done. See "nuisance2008" username videos on youtube for some of mine. Can't post a link from work. I was at Summt on 4/22, drove home 3 hrs, downloaded and made video of one session before I went to bed. I kicked it off anyway, takes a while to render the final product depending on your PC performance.

I used Harry's for iPhone but switched to TrackAddict which doesn't have all the features but is simpler. It does on phone overlay, capture of external GPS and ODBII (kiwi) and is written by the RaceRender guys so it integrates with that easily.
It also controls a wi-fi GoPro so it starts it recording when the phone starts recording, Harry's has this feature now as well. It doesn't play well with the kiwi wi-fi version for ODBII because they both create a network and the phone can only connect to one. Bluetooth seems to be the thing to get for ODBII so GoPro control works as well.
Overall a really nice system, at an auto-x you can walk the track with the phone and then watch that while waiting for your first run. After that you can watch your last run to see where you can make up time.

How do the phone app's get engine RPM? I understand using an external GPS to get location and speed but not sure how the phone can get engine information? I assume there is a cord that needs connecting to the OBD?
So I would need the phone app (Iphone), cord to connect to OBD?, video recorder, then Race Render for my laptop to merge the video and phone app data?
