high bit rate, 8bit.

shitty encode ! few new works of horrible is the same .
i was going through some of the things they did . and i think it's because they let the encode have various bit rate .

There are consistencies in what Horrible is doing.  There are several shows which he only offers in 480p and 720p.  Most of the others also have 1080p.  This probably is due to differences in network sources.  The shows which come in 3 resolutions tend to run: 480p about 180MB, 720p about 320mb and 1080p about 550MB.  The shows without 1080p tend to come in at 480p = 250MB and 720p = 580MB.  These titles include Kamasama Kiss, Robotics Notes, Code Breaker, Jormungand, etc.  These results are pretty consistent across these shows.

Now the "Why?" question:  I've never been able to find out that kind of info at the Horrible website, so I can only guess:
1. An attempt to make up for the lack of a 1080p quality option in those titles by boosting 720p parameters.  These 720p files are about the same size as those 1080p titles.
2. Something related to the lack of a 1080p option in those titles: signal quality issues, encryption issues, ?

I think #1.

Good or Bad: This issue highlights a big difference between anime fans world-wide right now.  Some of us are on metered internet service or have very limited speeds.  These folk want encodes that pack a lot into smaller files.  Others of us have unlimited and/or high speed internet service.  These folk don't care if an episode is 300MB or 600MB.  Additionally, some of us have massive storage or can add it, and some of us have limited storage.  Some of the info on Horrible's site suggests he's working out of a fat unlimited pipeline part of the world, at least for now.

Find sources that meet your needs.  For the size conscious, I think Commie is the best.  All their encodes are hi10p, tend to the smaller sizes and usually look pretty good.  And their scripts are often the best, even when just CR-Mods.
