Thomas is going to change the video wizard at some point so I was waiting for this before the tip video.
So far I have some 20 tips to produce but some are waiting for changes to happen first.
For now open version 5.x and under Tool's you will see video wizard.
This will convert the Equirec video to the 3:2 format Pano2VR requires.
Once done you add the first extracted Equirec to the first node.
Then add the video where it says Input Video.
Most browsers should support MP4 by now so I don't think there is a need to make an alternative format such as webm.
The idea is if the browser supports it you will see the video which will play natively in the browser, no plugin required. If it can not play the video you will see the still image.
Using the still frame you can set your hotspots etc.
Under the video input you can select the End Action.
As an example Node01 could be a still pano, node 02 could be a video pano, node 3 a still pano.
The end action for the video would be to open node03.
So from node 01 click a hotspot which can be a video of someone walking to a door and opening it, then node 03 opens looking in the room.
Making a video transition in effect.
Or each node is a video panorama. Note we can not track hotspot, so the video must be shot from a static point so hotspots on doors remain in the same position be it a still pano or a video panorama.
Hope this helps,
BTW have already pre ordered the new Theta S, be good to use this for the tip video
