I'm new to the drone family. I've recorded a handful of videos and have Subtitles turned on in the controller Settings. The mp4 files are there, but I can't find where the SRT files get saved. Are they supposed to be in the same 100MEDIA folder as the MP4s? If they're not there, is there another setting change I need to make?

If your drone creates a separate srt file, it will be in the same folder as the .mp4 file.
But some of the Mini series skip that step and put the subtitles directly on the video file and don't have a separate srt file..

Hi there, thank you for reaching out. Kindly take note that DJI Mini 3 does not generate separate SRT file and puts the subtitles directly on the video file.

Thank you for your understanding.
