QGroundControl automatically records telemetry (while the vehicle is armed, or just while it’s open if you set it to). It can also record the video stream, along with a subtitle overlay of the visible telemetry overlay values. Here’s a quick video of video recording in the default mkv format, and playback with VLC media player.
QGC itself can have the ArduSub logo in the top right changed to any image you want:
For having a logo on your recordings, you can either
- screen-record the QGC window (which means you also record the telemetry and other widgets, so the base video is partly covered),
- add one to the subtitle file (some notes here), or
- do normal QGC video recording and then add a logo to your video(s) with video editing software (can be done with ffmpeg on the command-line, if you want)
Always nice to hear an issue’s not on our end. Hope they’re able to sort that out for you
