It has been a long time since I read this stuff, but I am sure you
already know that an object movie differs from a linear one only in
having information stored in the QuickTime atoms telling it to be
treated as an object. It still is just a sequence of frames. Even
fancy multi-row movies are just sequences of all of the frames and
the magic of working as an object movie is just QT knowing the way
it is divided into how many frames on how many rows. This tells it
where to point to jump to the proper frame when you pan/tilt.
Back in the ancient of times, I can remember reading details on how
to take a sequence of images and import them into a linear
QuickTime movie, then (and here, of course is the part that is
fuzzy in my brain) just "telling" the movie to consider itself an
object and to use the proper controller. I think there was some
really simple and free utility that would do it for you.
Right, QTVREditObject, which is what I'm looking to avoid. That and
VRWorx and QTVR Authoring Studio...
The instructions I am recalling were back in the days of Classic
Mac OS. Probably System 7 even. Still you ought to be able to do
some automation somehow.
It seems you are likely on a Windows box, so I don't know exactly
what approach would work best for you. If you were on a Mac, it
wouldn't be terribly hard to automate it using VRWorx. It has
scripts for making panos or objects from a folder of images. All
you would have to do is write an Applescript to automate doing
multiple objects. Just start it and walk away. I don't know if
the Windows version has any equivalent.
Actually, I'm on OSX, though I am trying to keep my options open.
That said, my goals are simple (though unattainable at the moment) -
a faceless command line application that can be passed either a
linear movie (which I can already generate from the command line) or
a series of still images, along with the basic parameters (numbers of
cols x rows, animation or not, etc), and will output a proper .mov
I've assembled a toolbox meeting my criteria for *every* phase of
image processing and other automation needs I demand except this one,
tiny, legacy little thing called QTVR Objects :)
Yes, I can script VRWorx, but that breaks one of my key criteria here
(faceless). George Birbillis has the closest thing yet, but at the
moment it'll only cleanly compile on Windows. But it does exactly
what I'm looking for.
For reasons I'm not fully at liberty to discuss, those are my
requirements. Suffice it to say, robust, performant automation is the
key. Basic criteria for each tool involved include being callable
from a shell on OSX and Windows (and, in some cases, any other modern
OS - though I'm leaving that out for the QT-generating tools, though
it's doable with some hacks), preferably (but not necessarily) open
source, and stable and supportable. AppleScript may well serve as a
wrapper around pieces of it, but I won't be scripting GUI
applications for the core processing.
Thanks for the thoughts!
