You mean you get a Vegas error? If that’s so, you should check the Vegas COW forum.

Your link doesn’t work for me, sorry. Could you place a space on each side of the URL?

As for your problem, I’m not sure I understand, but here goes: Do not change any layers in your composition. Lock them all. The only thing you should change is the start and end of the work area (check the help).

Yes, if you render to a numbered PNG sequence, you can render in sections. Once you’re done, import the rendered sequence into AE, and drag it onto the new comp button at the bottom of the project window to make a comp. For audio, I’ll leave it up to you as to how to get the desired audio into this comp. Render this comp to a Quicktime movie — it shouldn’t take as much RAM given that you’re just rendering frames with no effects, no multiple layers.

It appears stretched in the computer. It would not be stretched on a TV. If you just want to play back on a computer, use a square-pixel comp preset.

Look up “non-square pixels” and “pixel aspect ratio” in the help.

You set the anchor point of the text arc to the center of the donut. To make an expression for the rotation of the text, drag the pickwhip to the Rotation value of the null and release. Multiply that expression by -1.

For example, the donut will rotate 60 degrees, and the text by -60. It will stay in place.

You change the start and end of the work area, then render.
Your Render Settings should be set to “render work area” to make this possible.

Check the help for “RAM preview”. Don’t use spacebar.

Yes. Weird.
If you’re in a rush …

… you’ve probably considered this, but can you do the composite in an editing app?

[Steve Roberts]

You should ask in the DVD COW forum or the Compression Techniques COW forum.

Yes, but do it as I advised. Import the AEP that uses comp A, then delete the stuff you’ve imported that you don’t need. Or make a copy of the AEP that uses comp A, and use “collect files” to collect the files for Comp A into a new, leaner AEP. Import that into Project B.

You can’t do this:
– link to a specific comp in a specific project
– link to a project
– import a comp without importing the whole project that contains it

It’s in the Help:
import a project
collect files
