How to force AE CS3’s H264 Blu-ray to encode 2-pass?
H264 Blu-ray is an encode option. I’ve used it. It’s also there in Encore. The codec, by MainConcept, is perfectly capable of 2-pass encodes, and it’s a very good idea to make use of the option.
Encore has dozens of presets, including all kinds of 2-pass options. After Effects has like five presets, with no 2-pass preset, and no apparent customization which enables 2-pass. The presets from Encore cannot successfully be imported to AE.
So… what to do?

ae can’t do 2-pass encoding because, until it is finished rendering, it can’t perform the analyzing pass, just the encoding pass. basically, it has to render each frame, compress each frame and save each frame, and thus a less efficient, lower quality compression…
what you should do is render the highest quality that you can from ae, then use software that can do 2-pass encoding, like encore. so, choose a codec like uncompressed avi or lossless mov or an image sequence like png, psd, or tif. if you don’t have the drive space for uncompressed or lossless compression, try photojpeg at a high quality setting. then compress to h264 with encore, or other compression utility, prior to burning a blu-ray disk.
