I have been trying to learn how to fly my GEPRC TinyGO 4k FPV Drone in Manual (Acro) mode which is harder than I first thought, but I am making some headway and I can actually fly now in Manual Mode without totally bailing within seconds. I will get better over time and this will smooth out the video for sure but my GEPRC TinyGO 4K even though the video resolution is not too bad there is no stabilization to speak of in the camera. It does however include gyro motion information along with each video in the form of matching .gcsv files that help GyroFlow figure out how to stabilize my videos.
There are a couple of tricks I have figured out that I needed to do to get the Gyro motion data to match up with the video data and once that is done the video actually looks pretty good in my opinion. Keep in mind my flying is really terrible and very jerky so better flying and less jerky movements will give much better results.
Here is my workflow when using GyroFlow to stabilize my GEPRC TinyGO 4K FPV Videos:
I pretty much left everything else set to default but you can play with other settings to get your desired output.
