As Android doesn't have support for overlaying anything on video sequences, alternate ways were devised to overlay the timestamps and GPS info on top of video files.
Generate subtitle files - subtitle files (*.srt) constitute a common way to include various text info, displayed at the bottom of videos. Most video player software (such as VLC) can use these files.
Overlay credits - an external online server is used to embed such info directly into the video files. Through the "Overlay GPS data" context-menu option, you can manually upload the desired video files to a special section of DailyRoads.com. To use this service, you initially get 10 free credits, and can later buy more through in-app payments (Android Market) or through the web site (PayPal).
Overlay template - You can choose what info to embed in videos, where to place it and what colors to use.
Converted video files - Finally, the converted files can be downloaded back to the phone, or to any other device.
