It is somewhat frustrating to me that the flight data is recorded with the video in a subtitle format.
There are formats specifically for recording GPS data and it would be great if that could be leveraged.
GPX file would be OK.. but would be great if it also could support fit files - that way other data such as altitude, control (throttle) info etc could be stored too.

Hi there. Thank you for reaching out. We will forward this suggestion of yours to our designated team for attention. We will keep you posted once we receive an update. Thank you for your valued support.

Sync you log files to a free airdata.com account and you can download in GPX and other formats.  Airdata are DJI partners for logs.

Or better yet consider subscribing to Airdata, it's invaluable IMHO.
