I turned on the video caption options on my Mavic Air but the SRT files are nearly useless. They only seem to be recording some basic camera constants and the mildly useful shutter speed info (if I have the camera in Automatic).

Any ideas if this is a firmware limitation at this point?

Hi, sorry to reply you late. This has been forwarded to our engineers for a check, if there is an update, we'll let you know at the first time. Thanks.

I recently wrote this on the topic.

The Video Caption doesn't recording GPS on Mavic Air, we will consider to add this feature in the further, thanks.

Hi, It has been a year now, and I still do not see the SRT file contains GPS, Altitude data, it is very disappointed.
