Note: The X1i (Euro version) of the phone is the only one that supports 30FPS VGA video. The USA version (X1a) supports 24fps QVGA recording, similar to past ericsson phones.
Also the X1i uses h.264 where as the X1a does not. Video recording quality on the international version will be about double the quality you will see on a US-Spec model.
Point being, if you are in the USA looking to get this phone you're not going to see the same quality from samples released now since the phone just started shipping the UK,Germany,Sweden etc.
