Hi,

to put hotspots in 360 video is easy, like in 360 photo's.
This will work all the way. For example the GSV like 'airhotspots'.
You don't need the moving hotspots for that.

Also with the moving hotspots it is possible to have clickable hotspots, works in html5 , vr etc..
You can trigger, like normal hotspots, any action you like.
The difference with moving hotspots is, you can put it on a moving object and distort it. So, with the editor you will be able to make that the hotspot stays on the moving object and also you can distort it. Position and distortion will change during time, when set of course.
The moving hotspots will create timeline(s). On different moments you can set what you want or how you want the hotspot to behave.
Of course there are many different ways of using this.
You can label items or people, sync your subtitles (using textfield), hotspots to change video to appear at the right moment... , but you can also give the dynamic 360 video a north. etc etc
This also works in 360 photo's with a small simple trick.
If you have more questions, don't hesitate and send me an email.

Hope it helps,
