I am turning on the subtitles option in the fly app.

After recording a video, i can turn on the subtitles in the video.

I see several information, like coordination, iso value, distance, hight, etcetera.

I also see the meter per second, so how fast it flying.
I want to see km per hour instead of meter per second.
When i fly, then i see km per hour, but not in the subtitles. How can i change the subtitles?

You can't unfortunately. I just tried my settings from Metric(m) to Metric(km) and did a quick 30 second flight. Viewing the subtitles, it's still showing as m/s.

Not only that, but no matter what unit of measure you select in the controller, the subtitles always show m/s.

You will need to load the subtitles in some software that can interpret them. For example (disclaimer, this is my own paid software): https://djitelemetryoverlay.com/

Is only my longitude without decimals? In the case of latitude, everything is correct. I was also surprised by the operation of shutter speed in auto mode.

The layout shown in your photo is exactly what I get on mine. You mention only longitude without decimals but highlighted the latitude figure, both of which have four decimals. I suspect you've confused yourself with the third number (29), which represents the number of satellites.

You are genius. Thank you. That explains it all. I was also surprised by the value of the shutter speed. I was expecting whole numbers, e.g. 500. You are also right with the latitude.

Thanks, steamship. I couldn't figure out what that value represented. To summarize, the Mavic Mini 2 video subtitles include:
f-stop, shutter speed, ISO, EV correction, zoom value, GPS (longitude, latitude, # of satellites), distance from home point (meters), height from home point (meters), horizontal speed (meters/sec).

Have I got that right?

Almost. Just missed the last figure, which is vertical speed (meters/sec).

I found it very easy to convert the raw subtitles to something much nicer, using Python.

This is the result:

May I know what program you used? Would like it simple like yours and not have too much data presented like in the default subtitle settings.

Use ffmpeg to get the raw subtitles from the video

ffmpeg -i C:\Path\To\Video.mp4 subtitles.srt

Then load the resulting .srt file into the DJI Video Subtitle Cleaner tool. Select what you want in the subtitles and click 'Process' and 'Save'.

You can then use ffmpeg or Handbrake to put the new subtitles into the video file.

You're very welcome.

If you see any changes that could be made, let me know. Right now, I'm working on making so you can extract the subtitles in the app without the ffmpeg command.
