I'm not aware of any HD limitations in Xvid. I got a 3840x2160 video encoded by Xvid here
However H.264 (x264) compresses more efficient than MEPG-4 ASP (Xvid). Especially at HD resolutions. And especially at low bitrates. So I'd definitely go with x264. At a given bitrate x264 will certainly produce better quality than Xvid (except for overkill bitrates where both look transparent). The only reason to use Xvid nowadays is compatibility to standalone devices that can't play H.264 video yet...

Overall H.264 is vastly more efficient than XviD or DivX, especially when you're dealing with relatively low bitrates. At the high end of the spectrum differences even out, but H.264 still comes out as being slightly better.
In short, go with x264 if you need to work with low bitrates at good quality. AVC > ASP

Very roughly MPEG-2 requires ~25 MBit/s to produce decent quality for 1080p HD content, while H.264 requires only ~8 MBit/s.
Of course this may vary significantly from source to source...

And of course HD + High Bitrate will give best quality

If your source is a Blu-ray, go with 720p at a medium (~2-6 mbps) bitrate. Otherwise, if it's DVD leave it at SD resolutions and encode at 0.8-3 mbps. All these values vary with respect to source complexity and quality.

And most important: The OP asked whether Xvid (MPEG-4 ASP) or H.264 is to be preferred quality-wise at a given bitrate. The answer clearly is H.264. This fact doesn't change, no matter on what forum it is asked/answered...

H.264 at 12 MBit/s should deliver excellent quality for HD content. H.264 at 24 MBit/s usually is overkill, even for 1080p material...
Just look at this 8 MBit/s 1080p H.264 sample: http://files.x264.nl/force.php?file=...0.48.8mbit.mkv (Looks excellent - and it was encoded with a pretty old version of x264)

You can't just lump H.264 and WMV and MPEG-2 together like that either Nor can you lump together 720p and 1080p, since the latter needs roughly twice the bitrate of the former... |

I think MPEG-2/VC1 will perform better in high bitrate because of their low compression method xD Quote:

I don't know well the 2 others formats but for H264 (x264) it will be something like this
[1080p] Low bitrate : 6 Mbps Medium bitrate : 8Mbps High bitrate : 12+Mbps [720p] Low bitrate : 2 Mbps Medium bitrate : 4Mbps High bitrate : 6+Mbps [SD (DvD)] Low bitrate : less than 1 Mbps Medium bitrate : 1.5Mbps High bitrate : 2.5+Mbps

Even at 720p, you can coax some very good quality out of video at something like 2 mbps, I've done it before
