Most DJI drones record flight logs as subtitle data. Learn to import it in After Effects to create custom overlays
Some drones record the data in a separate .SRT file (caption, subtitles), while others embed it in the MP4 video file.
Before your flights, make sure to enable the Video Captions option in the Camera Settings of the DJI Go 4 App
Yes. You can load multiple .SRT files on the Flight Data Viewer at the same time. They will be sorted and merged based on their date. This will allow you to visualize more complex flights.
It can visualize the data over map and satellite imagery and export the data to a range of formats
Yes. Expand the duration of your composition from its settings, unhide and unlock all the hidden layers and extend their duration as well.
Keep in mind that Adobe After Effects cannot import mgJSON files longer than 3 hours. If that is what you need, either find a way to compress the duration of your data before converting it to mgJSON, or use Telemetry Overlay instead.
Yes. Telemetry Overlay allows you to create your data dashboard without the need of third-party professional tools like After Effects. It has an easy drag-and-drop interface, hundreds of customization options and more gauge options and data types.
Yes, please! The Facebook community is probably the best place to do so, but if you prefer to do it somewhere else, get in touch to increase your audience.
Speed, Distance, Altitude, GPS Path, Altitude Path (graph vs time), Speed Tracker (graph vs time), Course Direction, Camera Settings (ISO, Shutter Speed and Aperture), Vertical Speed and Time. Some drone models do not include all the gauges
You will need to retrieve the .SRT files, located next to the video file in the SD card. If your drone does not generate the files (Mavic Mini, Phantom 4 Pro, Inspire 2), you can generate them from the MP4 file with the Subtitle Extractor.
Load your .SRT on the Flight Data Viewer to visualize your GPS on a map or satellite images. Then export it to mgJSON (After Effects animation)
Use the DJI Telemetry Overlay for After Effects to select the gauges you want to display. Import the MGJSON file, drop it into the desired gauge composition and use the Control layer's effects panel to set the imported data as a source and customize how it looks.
To some extent. The subtitle data of some models is not a 100% accurate and needs smoothing in order to look accurate. You can play with the smoothing control both in the DJI SRT Viewer and in the After Effects Template until you find the sweet spot for your use case and model.
Adobe After Effects 2020 or newer.
Not easily. For that, use Telemetry Overlay instead.
Pay once. Use forever!
Plus, get support for one year, then optionally extend it for a fraction of the initial cost.
