Does the Autoscroll-Vertical animation preset help? There’s information in the “Best practices for creating text and vector graphics for video” section about vertical scrolling speed for credit rolls.

Just to clear something up: Working in a linear color space doesn’t imply work in 32-bpc (bits per channel). Working in a linear color space just means that color operations are done in a color space in which values add together in a way that matches how light adds together in the real world.

We perceive and transmit colors/light in a non-linear way, which is why input and output formats are almost always “perceptually” (non-linearly) encoded. But intermediate compositing operations work better when they’re done on values that are not “perceptually” encoded.

There’s really nothing special for you to do to composite in a linear color space in After Effects other than checking an option in the Project Settings as described on this page. See this page for a little more information about linear light and tone response in general.

Now, to get to what your question really seems to be getting to: What color profile do you use for exporting? That’s a fine question, but I’ll repeat that it has nothing to do with the fact that you’re compositing in linear light.

If your output is meant for someone to actually watch, then you choose your output color profile to match the system that they’ll be using to watch it. See “Assign an output color profile”.

If you are exporting an intermediate file for some visual effects work, and the person receiving the file expects it to be a linearly encoded file, then you should choose Convert To Linear Light. But it doesn’t sound like that’s what you’re after.

If you want step-by-step instructions for working with color management and linear compositing, see this document and the overview provided here.

Oops. My bad. Sorry to get your hopes up.

I can’t find it either. I was going by some crusty old documentation that apparently needs to be updated. I had better get to that.

Did you set Rotation to Auto-Orient Rotation?

You can draw arrows as shapes on shape layers.

I’m not a Vegas user, but I can tell you that you usually need to tell your NLE to interpret the alpha channel appropriately to make sure that it’s used as transparency.

Also, make sure that you’re using a codec within your QuickTIme or AVI container that can encode an alpha channel.

If you only have 3GB of RAM, you shouldn’t be using Render Multiple Frames Simultaneously multiprocessing at all. See this post:

Using Photoshop filters directly as plug-ins in After Effects hasn’t worked in a very long time.

You can process frames in a batch in Photoshop and then import the image sequence back into After Effects.

Have you updated to After Effects CS4 (9.0.2)?

> Does that make;

– Millions of colors = 8-bit
– Trillions of colors = 16-bit
– Floating Point = 32-bit

Yes (though you’ll be well served to always specify ‘bits per channel’ to avoid confusion with ‘bits per pixel’).

> If so, does that mean when I choose the cineon format I can only export 16-bit DPX – since I only have trillions of colors as an option.

The Cineon format is specified to use 10 bits per channel. When you render and export from After Effects to this format, you choose 16 bits per channel (Trillions Of Colors), since After Effects only has color bit depth options for 8, 16, and 32—and a 10-bit color value can fit into a 16-bit slot in the rendering pipeline, but not into an 8-bit slot.
