The Video flight mode is used to manually fly the drone while collecting video data throughout the flight. The difference between this flight mode and manually flying in DJI Go are the video tags that you can generate throughout your flight. While flying manually you can select a trigger on the PrecisionFlight screen which will create a time stamp at that particular point in the video. Once uploaded to PrecisionMapper these time stamps are correlated with your video data.
This feature was built for inspection jobs. A good specific application that we have seen with this feature is pipeline inspection. The pilot will be able to fly the pipeline manually and mark any possible damage they see throughout the flight. Once the data is uploaded the video and tags can be seen by someone in the office for a more in depth analysis of the damage.
Before flying in this mode of PrecisionFlight you should fully understand the manual controls of flying your drone in P-Mode. For more information on manual flights with your DJI drone see your user manual. Review our PrecisionFlight checklist section to inspect equipment before leaving to the field location as well as necessary in field pre flight checks on the drone. This will include physical checks of the equipment as well as necessary steps to take in the DJI Go software before a PrecisionFlight survey.
1. Choose an ideal takeoff location at your area of interest. The spot that you turn on the drone will be your designated Home point through the entire flight. Account for takeoff, landing, and any emergency procedures that may be necessary.
We typically recommend an area that is free of obstacles and obstructions for at least 20 meters in all directions of the drone’s takeoff location.
You should also be within Visual Line of Sight of the drone throughout the survey.
2. With any necessary sensor already connected, setup the drone with charged battery installed. Have RC controller and tablet ready. Power on the Drone and then the RC controller by tapping the power button once quickly and holding down on the second push until the drone powers up. Wait for the green light to illuminate on the controller signifying a successful connection between RC and drone.
3. Close out of all other applications before running the PrecisionFlight app. Prepare to connect the RC to your mobile device using the provided USB cable.
- If you are using Android, connect the tablet to the RC, then select “PrecisionFlight” from the pop up bar and tap “Just Once”. This will ensure that you can use DJI GO when required.
- If you are using an iOS device, then open the PrecisionFlight app on your device and connect the tablet to the RC.
4. When ready select "Create Flight Plan" or choose from existing flight plan to start flying. Select "Video" survey type. For flight process using the "Grid" Survey type see our Capturing Data with the PrecisionFlight App article of the knowledge base.
5. Once you have selected this flight mode there is no need to plan any survey. In this flight mode you will be flying in the GPS enabled manual flight mode of your DJI Device. To takeoff slide up on the next screen. The drone will takeoff directly upward to 1.2 meters. From here you will have manual control of the drone.
6. Throughout your flight control the drone manually with the DJI Remote controller. On the PrecisionFlight screen you have a few buttons on the screen.
To begin or stop the recording of your video use the button on the right side of the screen (seen below in the "Record" state). In the Video flight mode you are limited by your DJI device when recording videos. The Micro SD card in your camera will only allow up to 5 minutes of video at a time. After 5 minutes you are able to begin a second video if space on your SD card allows.
7. Also on the screen through your mission is the "Mark Frame" feature. This will mark the video frame at a particular time stamp for you. When uploading your video these time stamps will match up with your video.
8. Another essential feature is the method of focusing your camera on specific objects throughout the flight. To do this simply tap on the object on the PrecisionFlight screen during the flight. You will see a green cross hairs icon appear on the screen at the focus point.
9. During all segments of flight follow necessary emergency procedures if the drone begins acting strangely or flies off the planned course of flight. Throughout the flight you should be within visual line of sight of the drone in case of an emergency. See Emergency Procedures section of knowledge base for more information.
10. To finish your video make sure you select the "Stop" button on the right side of the screen. Land the drone using the "Go Home" button or by manual control. Once the drone is landed and the propellers stop spinning power of the drone and the RC controller and remove the Micro SD card for data verification before leaving the field.
11. If you were operating the app without internet connection in the field you must regain internet in order for Marked Frames to get to PrecisionMapper. When you get back to internet connection open up the PrecisionFlight app and the data will automatically port over to PrecisionMapper in the background.
