Motocross aerial test with quadcopter

V010. Recording date: 01-02-2014

I broke one propeller some days ago hitting a tree branch, so I replaced them with DJIs, the only available at the store, as I wanted to fly asap. They don't fit perfectly with my motors, I reckon that could be one of the reasons why there's some jello on the footage. Besides, the cylinder of one of the propellers adapter holder is a bit bended because of that crash, and that's giving me vibrations for sure...

It was not the perfect day for flying: 25mph wind gust and my first time with too many moving objects on stage. Keeping my eyes only on the FPV screen was really complex, as the wind was taking the quad quite far away in a matter of seconds. For that reason I recorded 85% of the videos at a guess looking directly at the quad, and that's why I couldn't make another shoots I had in mind, like from a really high altitude facing down, or following the rider more closely, etc... I chose not to risk this time and avoid problems!

I'm still dealing with the slow motion settings in Sony Vegas, as I haven't been able to make these scenes look smoother. This time I've desabled resampling, and added the envelope velocity to set the speed at 50% (30fps). In previous videos (https://vimeo.com/niropter) I didn't take into account the fps for slow motion scenes, going under 30fps with the smart resample activated (apparently not good for fast scenes with dark background), and clicking the edge of the video and dragging while pressing control.
