Video mapping might require a more perfect timing because since you are
moving relatively fast, a difference in time between the two hardware could result to a mismatch of GPS coordinate and the captured video.</span></div><div id="yiv2174295766yui_3_7_2_33_1380247435214_55"><span style="background-color: transparent;"><br></span></div><div id="yiv2174295766yui_3_7_2_33_1380247435214_55"><span style="background-color: transparent;">--bunny</span></div><div id="yiv2174295766yui_3_7_2_33_1380247435214_55" style="color: rgb(0, 0, 0); font-size: 13.333333015441895px; font-family: verdana, helvetica, sans-serif; background-color: transparent; font-style: normal;"><span id="yiv2174295766yui_3_7_2_33_1380247435214_80"><br></span></div><div><br id="yiv2174295766yui_3_7_2_33_1380247435214_57"></div> <div style="font-family: verdana, helvetica, sans-serif; font-size: 10pt;" id="yiv2174295766yui_3_7_2_33_1380247435214_60" class="yiv2174295766yui_3_7_2_33_1380247435214_59"> <div style="font-family: 'times new roman', 'new york',

I'd
probably seen that GPSbabel could export in SRT format, but it didn't occur to me that this was subtitles as it was out of context. Question: how do you get the timing of the video and GPX to sychronise? For a start you'd have to make sure the video recording device and the gpx recording device had their time set the same. Do you sync them up just by switching them on at the same time, or is there a way to embed the time in the video? GPX has time information included of course.<br><br>Jim<br><br>-- <br><br> datalude: information security<br> e: <a rel="nofollow" ymailto="mailto:jim@datalude.com" target="_blank" href="mailto:jim@datalude.com">jim@datalude.com</a><br> Philippines: +63 2 403 1311 / mob: +63 917 849 3939<br> Hong Kong: +852
