How to "Overlay" with limited iPhone free storage

[gandalf]

So I have managed to Overlay all but one of my video's from last weekend. Unfortunately the only one I cannot complete is the longest (24min) video and I really want to Overlay the data. It is the only road-coarse footage that I have. I have tried dumping all pictures, music, video and apps from the 16Gb iPhone but HLT still wants another 3Gb to run the Overlay process. The only way to do that is to dump HLT app from the phone (thus deleting the 3+Gb video file).

How can I run this overlay process?

The 24min video file does have two sessions back-to-back recorded so maybe there is a way to split both the video file and the data file and overlay them separately (thus needing less storage room to render the overlay)??

Thoughts?

How many laps are mapped to the 24min videos? Only one?

Yes, one "lap" - even though there are a total of 7-8 actual laps of the track and some pit time of approx 2min in the middle, it recorded as one "lap" so I'm guessing I did not set the POI/start/stop correctly.

So I'm not concerned with lap times but I do want the video with rpm/speed data.
