In my opinion, h264 has the highest retained quality with the smallest file size. Xvid would be next best I guess. Larger files and a little more quality loss. And I hate DivX. It makes gigantic files and ick quality.

Thank you for explaining.
Yes, large files isn't that fun.
I prefer a drama being 4,4 GB, then it fits on one (data) DVD. Or if it's high quality, two DVDs, see "Seija no Koushin" each episode is about 800MB and fits exactly on two DVDs.

I wonder why ASP codecs such as Xvid and DivX are still being used by fansubbers today. Here's a quick comparison between Xvid and x264, the open-source H.264 codec. The original video from Apple's website was downscaled from 1280x720 to 704x396 and compressed (2-pass encoding, average bitrate 622kbit/s) using MEncoder. Although the resulting files were the same size, they looked very different:

H.264 is an ISO-approved part of the MPEG-4 standard. It will be supported by all the upcoming pocket-sized portable video players, along with the MPEG-4 multimedia container format (.mp4) which can also contain subtitles. The next Xvid codec (version 2.0, currently in development) will also implement the H.264 specification. Quicktime 7, VLC, MPlayer and Miro support H.264 out of the box. Plugins for DirectShow-based Players (e.g. Windows Media Player) are available. A VfW version of x264 can be used as a drop-in replacement for Xvid in VirtualDub.

Are there any reasons not to use H.264?

The only reason is that the world is full of stupid and lazy people who can't (more often WONT) educate themselves on how to use technology. How many people ask retarded questions that could be simplistically answered on the first hit of a google search? Amazing amounts of people are indeed this lazy. Or have forgotten that the internet can explain anything if you can read. They would rather look like a lazy idiot then take 2 minuets to google a term.

Though I do understand that there are a wide range of ages and demographics that watch these videos.... if you can use the internet to download dramas... you can use google to learn things.

When people get desperate enough they do eventually stop being lazy and figure things out themselves.
