After a bit of googling around, this should not be too hard using a subtitle format like SSA (<a href="https://www.matroska.org/technical/specs/subtitles/ssa.html" class="">https://www.matroska.org/technical/specs/subtitles/ssa.html</a>): This is a text based file format that allows to show text at specific times in a video and there are even some drawing primitives as well as image display included. And ffmpeg is able to read that and render it into a video stream.</div><div class=""><br class=""></div><div class="">As I myself am not a videographer (have not even taken images underwater), I wonder if there would be any demand for such a feature. I think we could simple export dive data to such a file format, not necessarily rendering a faux dive computer but just showing the information as a text for starters. Any feedback appreciated!</div><div class=""><br class=""></div><div class="">Best</div><div class="">Robert</div><div class=""><br class=""></div><div class="">PS: Does anybody object to asking a similar question in the Subsurface facebook account as I guess that would reach more of our users rather than just developers?</div></body></html>
