If you're asking specifically about Track Addict, you might have better luck in the
Track Addict Forum. I assume it can import a video and then overlay data along with some way to synchronize (or bump the video back and forth), but that probably needs to be done manually by finding something that occurs in both the video and the data (e.g. the first time the car starts moving out of the paddock).
In RaceRender, you would just choose the video as an input file, and then you can export a CSV from Track Addict to import as a data file into RaceRender.
