Hi, there are expensive apps like Telemetry Overlay that can do this but is there a free way? For instance converting the .srt telemetry to .fit and then importing that into DJI Studio and use the dashboard function to show speed, altitude, etc. I’ve tried to covert .srt to .fit but can’t find a f…

I will have a more thorough update today, but in the meantime - what file do you actually import/upload to AirData? Because the AirData csv clearly contains so much data - like ailerons, rudder, throttle, battery etc - that it must be coming from somewhere (which is not SRT). Is that some flight log…

Ok, so I think it makes what we discussed earlier clear - the Fly App logs the entire flight, SRT logs only data when the camera is recording (and limited metrics only). OVRLEY (and probably TO) syncs the video with SRT/CSV/GPX by timestamps (even if the length does not match) and that’s why it doe…

[image] spirokai: I think what makes most sense for now is to focus mostly on support for AirData :+1: Again @spirokai thanks for your help with this

Chances are that the .csv from Airdata varies in content depending on the age/model of drone, too .. though I expect the headings remain consistent for the data they contain. [image] spirokai: OVRLEY (and probably TO) syncs the video with SRT/CSV/GPX by timestamps (even if the length does not m…

[image] milkmanchris: the SRT file is only the portion of the flight where you are actually filming I should have realised this, because each time I change camera on my Mavic 4 Pro, a new srt file is saved along with the mp4 and lrf files.

Been spending some time with OVRLEY and I’m very impressed, it’s got much better widgets than Telemetry Overlay and they are very configurable, you can get them just how you want them. :+1: [VAN !!!]

At 6 secs .. where you are almost stationary and turning 180 .. why does the speed shoot up to 10mph? You’re certainly not moving anywhere near that fast.

Is there a free way to put telemetry onto a drone video?
