If you would like a solution to your problem please post a download link to the panorama image for testing.
It is the only real way to come up with the answer. Otherwise everything is simply a guess and this is why you are not getting replies on the various forums you have posted this question.
Those look about right to me. Looks like your using a One-Shot set up? Better equipment will get you better results.
You could also try slowing the speed down a touch.
I cannot be seen because of 503 errors.
However, "shaking" is guessed to be a phenomenon in movie and walk through.
EP said that cannot be solved.
They seem not to work on this problem solving in TW4.
The thing that we can do will use TW3 or slow down the speed or wait for TW5.
Or, give up and use it.
The phenomena are different by rotary speed and PC specs.
The shaking cannot be confirmed with PC of low specs.
Old PC before Pentium D and Mac are hard to understand a phenomenon.
When you change a radar and a movie button arranged to a map in Hotel Virtual Tour (Purple Mountain Hotel) and compare it, you can confirm a difference.
When I finally got your tour to load after hours of 503 errors I got to see your panorama working normally. There was no shaking of shuddering. It sounds to me your personal computer is under powered or you simply have too many apps running at once.
What are your computer specs? CPU, Ram, Graphics card etc?
Worked ok for me although seemed to hang at 66 percent (loaded quickly until then).
Maybe 'stepping it back' from the zoom level would help - makes it look less blurry and also solves the 'slowing it down' as you pan around problem a bit.
Not a bad tour though - much better than I managed for ages certainly!
