DJI SRT flight log
Also known as: DJI SRT file, DJI video subtitles, SRT telemetry
A subtitle file a DJI drone can write next to each video, holding GPS position, altitude and camera settings over time. It is not needed for editing.

What it means
Many DJI drones can save an .SRT file alongside every video clip. SRT is a standard subtitle format, but here the "subtitles" are flight and camera data: a timestamp, GPS latitude and longitude, altitude, and exposure values such as ISO, shutter speed, aperture and EV. Open one in a text editor and you will see a block of numbers for each frame or moment of the recording.
Despite the common nickname, it is not a full flight log. The detailed flight records with stick inputs, battery data and warnings are kept separately by the DJI Fly app. The SRT is closer to the GPMF telemetry GoPro embeds inside its files, except that DJI writes it as a separate sidecar file, much like a GoPro LRV companion sits next to its video.
How it works in practice
The option is usually called Video Subtitles or similar in the camera settings of the DJI Fly app, and on some models it is on by default. The file shares the video's name, so DJI_0042.MP4 gets DJI_0042.SRT, while newer drones use longer names that include the date and time.
People use SRT data to check which settings a great shot was filmed with, to plot the flight path on a map, or to build a telemetry overlay showing altitude and position on screen. Some media players also show it as live captions when both files sit in the same folder, which is a handy way to review exposure while scrubbing through a clip.
What to watch out for
The SRT contains exact GPS coordinates. If you hand original files to a client or post raw clips publicly, you may be revealing your home or a private launch spot. Leave the SRT files out whenever the location is sensitive.
It is also easy to break the pairing: rename the video and tools no longer find the matching subtitle file. Some editing software imports SRT files as a caption track, which clutters the timeline. If you never use the data, you can switch the setting off. If you do, back up the SRT files together with your raw footage instead of copying only the MP4s, because they cannot be recreated later.
How RawClip handles it
RawClip does not read SRT files or use telemetry, and it does not add data overlays, so there is no need to upload them. Send only the MP4 or MOV video files from your drone; the AI analyzes the footage itself for motion and peak action. Keep the SRT files in your own archive if you want the data.
