I'm having trouble getting my video render to look the same, quality wise, as my view in After Effects.

Here's a screencap from my After Effects view. Full resolution, 100%.

Here's a screencap from the video playback in Quicktime after render. Best Settings, Lossless (Animation).

What render settings do I need to get that text crisp?

Do a quick test with a single image render.
Select Tiff, Trillions+, LZW off
It should remove the banding and fix the text. A lot of codecs are only 8 bit millions :/
Also make sure you're running at least 16bpc and are not using 8 bit plugins.

Single image render based on those settings does indeed look fine. I also switched to 16bpc and tried rendering as Lossless again...but the same issues are still persisting.

What codec do you suggest for exporting the actual movie (instead of just one frame)?

any 10bit or higher 4:4:4 codec that support trillions+ of colors. I recommend cineform 4:4:4 or ProRes 4444, both are good. Also, you can render out image sequences then burn them into mpeg's if your software supports it or just settle for adding noise or slight blurs to video. Search the cow for "banding" for more detailed instructions.

The more I look at this, the less I think it's a banding issue.

If I remove all effects/gradients/etc and just have a white background with a single solid color line of text, it's still "soft" around the edges of the text when I render with Best Settings, Lossless.

Do you mean the quicktime player, or Final Cut Pro? FCP's viewers are notoriously poor, and you can't judge the quality of ANYTHING with 'em... look at a video monitor.

Does this file contain interlacing? If it does, you can't use ANY kind of viewer to judge quality.

No, I'm specifically referring to QuickTime Player. I'm not using FCP for anything at this point in the project. And no interlacing.

What's not making much sense to me is that even if I set the compression codec to "None" and just render it as a regular QuickTime file...it still has this same problem.

The only way that seems to avoid the problem is to render as a TIFF sequence with trillions of colors...which creates prohibitively large files (7GB+ for a 10 second clip).
