Sorry … 30 marks, one every 12 degrees, not every three degrees. Yikes.

Well, the resolution is higher if you need it for, uh, print, I suppose. 🙂 I haven’t done a test, but there’s probably more latitude in the high end of the stills curve compared to video. Also, you can effectively make the turntable run more slowly than its motor can, by increasing the number of marks and moving it incrementally. Also, still cameras are naturally progressive, not interlaced. If you shoot twice as many frames, you can render to interlaced in AE later if you need it.
The advantages of video are that you can run the turntable at a constant speed, so it’s easier, and you’ll get motion blur.
However, if you want to apply motion blur to the stills in AE, you can use Reelsmart Motion Blur.
I’d probably go with the stills for precision.

If you can get ahold of the turntables used by QTVR producers, that would be great, since they’re designed to be rotated in specific increments.
If not, you could use a DJ’s turntable, and apply tape to the edge. Mark the tape in increments corresponding to the speed of your rotation. If you want the product to complete a rotation in one second, mark the increments every three degrees, or make 30 marks evenly spaced around the circumference of the turntable. I’d recommend doubling the number of marks in case you want to slow down the rotation, and/or apply the Twixtor plugin to slow it down even further.
Next, you cover the turntable with bright green material (ideally, greenscreen material), then set up and shoot the product with a digital stills camera, carefully rotating the turntable so the marks line up with a rock-solid index pointer clamped to a static part of the turntable. Make sure everything is rock-solid, including the product.
Once you’ve shot, you bring the stills into AE. If the camera numbered them in sequence, you just import the stills as a numbered sequence.
Hope that helps,

[Paul Carlin] “Be aware that if you have two instances of AE rendring something very intense, you may have a hard time regaining control of the system due to the processor time being used up by AE.”
This is true. Both processors will pin at 100% (good) but the computer is basically useless for other tasks until the render’s done. (bad)
Of course, you can always pause the render to do what you need, then resume. Or pause one render, and let the other one take it for a while as you do something else.Steve

Cowdog is righteous on this one, as always.
Contact the owner of the copyright and pay the fees if you want to use the song — it might not even be an option. If your client doesn’t want to do that, you should bail, or at least convince him/her to use stock music, for the applicable fee of course.
Even if you make your client sign a piece of paper that holds you harmless for any legal action taken against your client, you might still be liable.
Caveat: I’m not a lawyer, though I do occasionally use italicized latin words.

Search the COW for “secret”. It’s a prefs setting that might help your renders.

That’s about it. Fancy graphics cards don’t help, since AE’s OpenGL implementation isn’t very good right now. Many users switch it off.
There are no AE hardware accelerators out there. The Blue ICE cards used to serve that purpose, but they’re obsolete and have long since been abandoned.
However, if you want to speed up your renders considerably, set up a multi-instance render. Use the “multi-machine” preset, then save that project. Next, from the command line, launch a new instance of AE thusly:
“C:…Program Files…Adobe…After Effects 6.5…Support Files…AfterFX.exe” -m
(dots substitute for slashes here – COW don’ like no slashes)(keep the quotes and the space-dash-m)
Open the project in the new instance and hit render. Remember, this only works when rendering image sequences. When done, do a quick render of the sequence into a movie if you like.
Hope that helps,

Can you copy the Premiere project and footage to the AE computer?

Trapcode’s Sound Keys plugin should do it.

Did you search the 2003 COW archives for “dots” with “Ebberts” as the author?
