Roger,

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.

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.

Ok, where have all the object VR tools gone? I've got what I hoped
was a simple task (compared to, say, creating panoramas from the
command line) but while I have come up with solutions for the hard
stuff, I've got bupkis on this.

I need to find a way to convert a sequence of still images, or a
linear movie (made from that sequence), into a proper QTVR
Object .mov - how hard can that be? My major caveat is I'd like to do
this without GUI apps... no QTVREditObject, etc... and I'd really
like to do this from a simple text-mode (shell) application.

I'd be willing to pay for someone to write such a tool if nothing
exists. I had hopes for both Qt_tools and QTCoffee, but neither can
do the last part (convert to Object Movie).

I even tried using the "muxmovie" command to merge the video track
from a new image sequence with the other three VR-related tracks from
an existing object movie... and ended up with a non-functional movie!

All help most appreciated,

Roger
