Hi Tony,
Thanks for the follow-up, always good to chat, never know what ideas may come up.
Yes you are correct that in theory the viewer can choose to look in any direction within the 360 degree sphere that they please. And yes, trying to "move" this around probably could lead to all kinds of disorienting effects.
However from a practical standpoint there always is a "starting" view. And that is typically what is used for thumbnails, and is the first thing people are seeing when they encounter the video. Kind of like a scrolling webpage that has content that you see first at the top. And there is a risk that stuff at the bottom gets lost or never seen unless prompted somehow. With the 360 videos, you may lose your viewer before they even realize something cool is happening out of their initial field of view. And the field of view in facebook, youtube, and even in the headsets such as oculus or Samsung gear probably only shows 1/8th of the total sphere of video. So its easy to "miss" something cool in the scene if you aren't somehow directed to it.
I can imagine especially in some unplanned or impromptu videos that catch something unexpected that may occur 90 degrees or 180 agrees from the intended subject, that THAT may end up being more interesting than what was planned.
I've been working on this all day, with a few different leads as to solutions to the problem. 1. Facebook as part of their encoding and processing gives you a choice to set the initial view that they will display. 2. Youtube does not. 3. Adobe Premiere has a tool that will allow you to change the position (and even rotate it mid-video), but only in the horizontal axis 4. I just can't find that functionality in PowerDirector 15, am doubtful it is in there.
Lastly I've got a lead that you may be able to edit the metadata package for the 360 video to include tags that set that initial view. Which could solve at least that part of it.
Thanks for your response and hopefully this is somewhat helpful.
Have a great week!
Darren
