Yeah should do, any movement that gets picked up by the quad’s IMU is used to smooth things out. Yesterday’s flight wasn’t a propwashy kind of flight though. I’ll try again at some point with some more agressive freestyle flying, although that comes with other issues…
The main difficulty is that the cropping still has to be done manually. You end up with a smaller video with a black border around it and the location of that video within the frame (or relative thickness of those borders) moves around a little. You have to crop in your video editing software such that the video stays visible and the black borders don’t encroach into your crop. On the video above, flying mostly nice and smooth, the frame doesn’t move around too much so you don’t need to crop loads. If I do a really fast snap roll, the stabilisation moves and twists the visible video right over to one side and so you’d have to crop really really small and lose most of your resolution (and field of view) to avoid having the black bars come into view. For example, the bit toward the end of the video where I do a fast 180 over the small fence, I’ve cropped that whole clip to a smaller FOV than the rest of the video as the stabilisation was quite severe there.
Obviously you can adjust the amount of stabilisation - I could turn it down if I was doing lots of freestyle moves which would then require less cropping, but then there’s a tradeoff with how smooth it all looks. You really have to plan before flying - ‘am I going for a smooth cinematic flight or am I going powerlooping and rolling and spinning about?’. It’s difficult to accommodate both in one vid and make it look seamless and consistent.
If you use Warp Stabiliser in Premiere or iMovie’s stabilisation function (or probably RealSteady Go, but I haven’t tried that), it constantly zooms in and out to minimise the crop as much as possible depending on how much stabilisation is needed. You often see the FOV zoom in during a roll then back out again. You could do this yourself in Premiere with the Gyroflow footage by timescaling the crop values with key frames etc but it’s a bit of a ballsache.
On the whole, the results are night and day better than any optical stabilisation done by video editing software, there’s no substitute for actually using the gyro data. There are undoubtedly better commercial solutions out there, but for a free piece of software I’m pretty impressed.
