Danny, Dave:
When in the After Effects Render Queue you specify a format that’s typically used for distribution (H264, MPEG-2, Flash video), the Adobe Media Encoder dialog appears when you invoke the Output Module’s format options.
As Dave said, because of the way After Effects works, AME can’t do multipass encoding (note that for some formats this produces critical quality advantages; for others, not so much). But it’s true that as of today, exporting to distribution formats in AE is more about convenience than having the ultimate quality option.
However, starting from CS4, the Adobe Media Encoder also exists as a standalone application.
If you have Production Premium or Master Collection (ie, if you didn’t buy After Effects as an individual product), you can avoid rendering an intermediate, uncompressed file for encoding later. Instead, you can open the After Effects Composition directly in Adobe Media Encoder, and encode using 2-pass VBR encoding. As a source for encdoing, of course, the “raw” After Effects Comp is the same or higher quality than an uncompressed file.
If you did buy After Effects as an individual product, you can still render an uncompressed or slightly compressed file, and use that as a source for encoding in AME.
As for H264 (even MPEG-2) being correct if you’re not “too picky”…
I agree with you if this was about using them as acquisition formats, but distribution is that they were made for.
Given enough data rate (say, 25-30 Mbps) H264 should look gorgeous. It’s what you see in a Blu-Ray disc. At such data rates, 2-pass MPEG-2 also looks better than it has any right to. And it’s less demanding on CPU muscle than H264. Playing full HD H264 video requires a powerful computer.
An uncompressed HD file can be about 100-120 MEGABYTES a second. It would require special hard drives, or a stripe set to play back correctly.
