A Tunnel survey contract required textual captioning to be flashed up on the recorded video in real time. A market search failed to find a suitable system. In a matter of days, Vocean engineers created a captioning tool which allows edited text to be posted ‘on the fly’ and then removed after a short time. This is invaluable for identifying specific features and marking events. Regular messages are stored in a list and can be summoned as and when required.
