unlike if you publish a QTVR as a standalone in the internet you achieve
fullscreen by the HTML-Code (set width="100%" and height="100%" and
<param name="SCALE" value="TOFIT">). As Landis and Don is doing this for
you, so Harald is right just provide a very large QTVR.
I just want to ad that a large VR means for a cylindric a panorama with
900-1400 pixels height.
If your movie has a FOV of max 75, equivalent to a 24mm lens I usually set
the
initial Zoom to 100% so that you still get a little resolution left for
Zooming in.
The actual display size of the movie can be anything.
The fullscreen display in browser is set in the Html code as Rolfo said.
A Cubic movie should be minimum 1200x1200 cubefaces.
I recomend 1500x1500. It depends on what tool you use to make them.
Panocube makes 1500x1500 as default from a 3000x6000 panorama
Make Cubic makes 1900x1900 as default and so does CubicConverter.
In CubicConverter (Mac) you can choose to downsample the cubefaces to
smaller
from your original high resolution panorama. That gives you a much better
quality.
The optimal resolution from a 3000x6000 is 1600x1600 pixel but in most cases
a 1300x1300 will give you a pano which you can not distinguish from the
default 1900x1900.
However you get a download which is almost half the size.
However CubicConverter and possibly Stitcher are the only softrware which
you can use this way.
For compression use 30-50% JPG.
Note that Panocube uses an irregular scale which is not standard.
A compression of 50% in Panocube is equivalent to a compression of 32% on
the IJG ( Independent Jpeg Group ) scale which is used by QuickTime tools
and in Photoshop on Mac and PC.
A Panocube compression of 78 is equivalent to 50 on the scale used by other
software.
