I exported a music video using H.264 for the first time (I would normally just use a simple Apple intermediate codec) and as the 1st shot fades up, for the duration of the fade up, there are ever so slightly visible 'lines' across the white background. It is literally just for the 1st second of the clip, but being the opening shot it's rather important. check it out, it's more obvious at 1080p
By the way, yes it is meant to be out of focus and grainy.
I set the quality to 10,000KB/s which as far as I'm aware is pretty good for online streaming?? I use Final cut express 4.1
Any help would be greatly appreciated as I have no H.264 knowledge at all
