3000kpbs at 1080p or do you resize down?

Frankly 3000 is a bit on the low side even for 720p and since you're also using LSF, it'll probably look even worse with such low bitrates. On top of this, you want to preserve grains at this low bitrate as well? With such low bitrate, you're better off to REMOVE the grains.

Since bitrate is obviously not your main concern, you should just use CRF setting instead of 2-pass bitrate setting. This way you won't need to increase your bitrate if the result is not good enough for you.

Try for example maybe CRF=24 to get around 3000kbps for 720p encodes.
This depends on the source, movies with much dark scenes, the bitrate will be much lower at a given CRF.
