No. Our software saves the subtitles as soon as the video recording is stopped. The subtitles are generated on camera based on the settings.txt file stored on the memory card at that time. Changing the options in the settings.txt file will affect subtitles of subsequently recorded videos only.
Optionally, the CSV sensor data file or GPX format GPS mapping files may be used with DashWare at any time to generate visual gauges of your choice.
Note: the GPX files are available only when using the Alti-Force GPS mobile app paired over Wi-Fi with a Hero4 camera during video recording.
