Hornsdale SA, Tesla battery and wind farm

Yes, iMovie for clipping, any speed alterations, adding dissolve / fade between sections, then save in 1080 and 720.
These are then opened in the DJI app editor, and add some music, which is a bit limited.
After adding music, I then save those in turn 1080 and 720 res, and delete the silent ones.
So when I see the 2 vids on the ipad, I know which is 1080 and which is 720.

Not sure why I do the 2 res, maybe because youtube sometimes reduces quality, and I've had to upload in 720 a couple of times.
Not much difference between the 2 in file sizes when transferred to the main laptops, I noticed a few times.

With the music, one of these days I will find out how easy it is to find free songs on the many free and commercial websites, and get some new ones onto the vids, there are many nice quiet songs that add to the otherwise 'silent movie'.

DJI editor music can be added to, go to more music somewhere on there, as there are maybe another 10 or 12 songs you can download, and some of them are good.

Yes Dicky, that was actual except for the obvious 3 or 4 seconds I slowed it down for the slow motion effect.

Some of the turbine blades nearby were going a lot faster that this one, others barely moving.
I think it is mainly eagles, hawks etc that are slow moving air current flyers that have issues with the blades.

I suspect you're right, DickyBeach. Some interesting numbers posted in the last item on the Hornsdale FAQ.

But those stately turbine move at quite a clip.....

The blades at Hornsdale are 55m long. 12rpm is a typical rotational speed in a good breeze, so with a 3 blade turbine, that's 36 blades a minute, or one every 1.7 seconds. At 12rpm the tips are doing just under 250kph. 1.7 seconds to dodge between things coming at you at 250kph. Best not to be there, except for Indian Mynahs, of course :-)

That's at the tips. Closer to the hub, it's still 1.7 seconds between blades, but they're moving much slower, so perhaps the poor bird would only get a bump if it mistimed its attempted passage.

Looking at the video, the rpm seemed to be about 6. So tip speed would be about 125kph and the interval between blades about 3.5 seconds. Still a bit risky to play chicken.

LOL

Yes, the blade tips on those big turbines are moving much faster than it may appear to the eye!

Strangely unnerving, shadows look faster.
Early morning or late afternoon shadows would look amazing from above looking straight down.
Must remember to do this if near turbines sometime suitable.
