I found this post on the Barnes and Noble forum:

FINDINGS

----------------

ok, the Nook Color has a resolution of 1024x600, which is an aspect ratio of 1.71

720 seems to be the maximum width of a video, so at 1.71 aspect ratio the correct width should be 421 pixels.

I encoded a video with a width of 721 pixels and it would load the player, but then crash and say it couldn't play the file. Anything larger than that and it doesn't even attempt to load it. So apparently 720 pixels is the built in maximum width for video files.

I did not discover a maximum height, however it's irrelevant.

ENCODING

-----------------
I encoded all of my test videos with MPEGstreamclip which is a free tool. I would assume these settings would also work in HandBrake.

(if you're unfortunate enough to be on a Windows computer you will also need Quicktime Alternative 1.81 to run MPEGstreamclip properly)

BASICS

------------
Just make sure you're set to MPEG-4 encoding, 720x421 (640x480 for 4:3 content) and you should be good.

Here are my Compressor presets (if you have a Mac and Final Cut Studio)
