..The tragedy here is that the CG is a core part of the presentation in FFXIII and it seems to be the case that
the company has paid little attention to the poor quality of the final assets on the Xbox 360 version. The Microsoft XDK ships with a
VC1 decoder, giving it the ability to playback video files encoded using technology supported by Blu-ray discs and players. Indeed, movie pirates out there get
excellent quality VC1 encodes of Blu-ray movies that manage to fit onto a dual-layer DVD and run from the Xbox 360 dashboard.
Decent encoding takes time and effort, but the results can look good - even on challenging material. Combine this with the fact that the game
doesn't need the 1080p-sized video the PS3 version boasts, and we have the ways and means with which to attack the compression issue from two different angles.
Square-Enix has bought in the
Bink compression system for FFXIII on 360 and its failure in high-motion, colourful scenes does suggest a
constant bitrate is being used as opposed to variable bandwidth that allocates more data to
maintaining image quality on more complex scenes.
This failure is compounded by the fact that Square-Enix
hasn't even made full use of all the disk space it has available.
Around 1GB of storage is left empty on discs one and two of FFXIII, and you have to wonder why all that empty space couldn't have been
repurposed for higher bandwidth encoding. Perhaps it's because of the background loading taking place while the cut-scenes play out, but regardless, the hit to quality using Bink is often
unacceptably bad.
....
The results in Final Fantasy XIII aren't up to snuff - frankly,
the encoding looks amateurish.
