You got it! Not enough free memory! I repeated the overlay command after clearing some space and it worked!

Thanks Harry!

There was no error messages. The overlay completed. But video does not have overlay. When I play the video on iPhoto app theres no overlay at all.

Over 6400 frames.
Video was sent to Photo app.
Back in Lap Details, but thumbnail shows same video (without the overlay).
Process never stopped. Looked like it completed normally.

Hi Harry,

Tested the laptimer this weekend. Got good videos but when I tried to overlay data, it wasnt imbedded in the video after processing. I uploaded video (after overlay) to macbook thinking the iphone 4 could not display video, but the video still did not have overlay on the macbook. Thoughts?
