You mean HUD graphics on the video?
I, as do many others, use a phone app that uses the built in GPS. It logs the data which can then be exported to a software that maps the video and
speed.
I have done it, see below. I used Trackmaster for my Android (Harrys lap timer for my iphone) and Racerender to mesh the lot together.
Track days ARE the best thing since sliced bread, until I get a supercharger that is!
Please read my ring story:

Using regular phone gps for speed is pretty inaccurate, mainly for reaction time as generally they only work at 1 hz.
Heres me using a racechrono app to log and race render to present he video. Notice how slow the speedo is to react.

Then this is my latest, using same software but running a 10htz qstarz blue tooth gps receiver.
The revs and throttle position were logged on racechrono via a bluetooth obd reader, which obviously needs a car with a plug.

If you have a camera that records the GPS or some other log such as ECU log you can use Dashware to put telemetry on the video.
