Telemetry Overlay for Mavic (and other models) in After Effects

[0Kajuna0]

Hey guys,

I've been working on a system that uses the SRT flight telemetry to create customizable gauges in After Effects: a dashboard with speedometer, GPS path, altitude, heading, distance, ISO, shutter speed and f-number.

Here's a demo and a tutorial:

There's also a tool to export the data to a bunch of formats (GPX, KML, CSV, JSON, GeoJSON...) but that's been available for a while.

It's compatible with the Mavic (Pro, 2, Zoom, mini), Phantom (3, 4, Pro), Inspire, matrice 200 and maybe some more. In some cases the data has to be pre-processed with a script first.

Some screenshots:

Someone has done this already.
I'd like to see someone use the TXT flight log file which has more robust data.

Mini doesn't have an SRT file. Instead it has a subtitle track in the video file. I couldn't get Windows Media Player to see it, but worked with VLC.

That looks really cool. Is the only cost, the cost of the template?

Assuming you already own Adobe After Effects, yes. The data conversion tool is free

I know about the Mini, I included a script to extract the subtitles to a file.

Yes, parsing the flight logs would be a natural next step, if I ever find the time.

That would be awesome for a presentation. See the video. See the flight path on the map. See the telemetry.

I love telemetry, I'm getting few errors trying to extract data from video, Windows 7 running in VM on MAC

 

[0Kajuna0]

I have not tested this on a Mac. The batch script extraction is just a workaround until I find the time to code a proper solution (I just need to find the time...). Will try to test this and get back to you. Thanks for the feedback!

 

[Deleted member 109934]

I have run that on Windows 7 in VM Environment, I will try to download those .dlls manually, later on, I'm sure it will work.

 

[DanMan32]

Or reinstall mp4box, since that's what reported the error.
Also a VM might not have the needed video handling.

I've quickly put together this tool that extracts the subtitles: Subtitle Extractor for DJI Drones

I've tested it with a couple of Mavic Mini files and it appears to work well. I would really appreciate it if someone else tested it, especially with Phantom 4 Pro or Inspire 2 files (which I don't have at the moment).

Thanks

Since the M2 used SRT files rather than embedded subtitle track, the P4Pv2 and I2 are likely the same.

No. I'm not sure what DJI's criteria is, but the P4P and I2 store the subtitles inside the mp4 file.

 

[DanMan32]

Really? In that case strange it was still SRT for MA and M2.

 

[0Kajuna0]

Yeah. It doesn't make sense, but neither does that the Mavic 1, 2 and Mini include GPS coordinates in the subtitles and the Air does not.

Has anyone been able to test the subtitle extractor?

Thanks!

but neither does that the Mavic 1, 2 and Mini include GPS coordinates in the subtitles and the Air does not.

even the M2ED creates .SRT files but with very strange coordinates:

00:00:00,000 --> 00:00:00,033
<font size="36">FrameCnt : 1, DiffTime : 33ms
2019-03-06 16:39:02,569,925
[iso : 110] [shutter : 1/60.0] [fnum : 280] [ev : 0] [ct : 5055] [color_md : default] [focal_len : 240] [latitude: 0.843114] [longtitude: 0.207163] </font>

it should be: GPS(48.2629,11.8577,0.0M)

It seems every department within DJI responsible for a specific type of aircraft has a different code for the same procedure (create and write .SRT content)

 

[DanMan32]

Yep. Which is why I was surprised the M2 originally was missing features the MA and MP had. I figured the M2 would be the best of what MA and MP each had. Should have been shared code.
