LiNE release has a custom quantization matrix, which is forbidden
It also had problems with subs (although to their credit, they did release a subfix).
We have used h.263 quant matrix for maximum standalone compatibility.
[Verbose Proper Reason]
We were very excited when we saw this pre, we feel it is easily one of the
best films of 2006, so we downloaded the LiNE release, burned it to disc
and started it up on the standalone. Unfortunatly it looked terrible.. lots of
pixelation, big obvious macroblocks and various other artifacts. Upon further
investigation our suspicions were confirmed, LiNE had used a custom quant matrix.
The matrix in question is AutoGK's default matrix, which leads us to believe that LiNE
have one-clicked their release.
Many people do not know or fully understand what the quant matrix is or why it's important.
A simple explaination is that the matrix is essentially a series of threshold values
for the DCT that is used to quantify the amount of 'detail' that should
be put into a block. These thresholds dictate what detail to keep and what to discard
depending on how much of a change in average luminance there is between other 'pixels'
in the block. Depending on the content of the video, some matrices are better than others
and can produce better (or worse) results. The two default xvid matrices, H.263 and MPEG,
are good allrounders and make a nice job of most types of video content.
The problem with custom matrices is mainly hardware compatibility with standalones.
"- Quant. Matrix always has to be H.263/MPEG due to lack of hardware
support for Custom matrixes. " - txd2k5
The majority of standalone players do not support custom matrices and exhibit artifacts, pixelation
and other problems that seriously degrade viewing enjoyment. Some players even crash or show no video
when trying to play a movie with a custom matrix. The other danger of using custom matrices is
if one dosn't fully understand the relationship between the matrix and the type of content they're encoding.
In LiNE's case, it is the AutoGK default matrix, which generally is pretty good on most video content.
Sadly, a lot of groups are one-clicking their releases with autogk (m00tv, FTP, etc) and also having problems
with it using a custom matrix. We would encourage groups to use regular GK or other tool that dosn't cause
problems. If groups really insist on oneclicking with autogk, please enable the standalone compatibilty
flag in the hidden options. This should produce a scene standard rip that will play fine on standalones.
If you have already downloaded the LiNE release and only intend to watch it on your PC and arn't
bothered about subs, or don't care about scene standards, then feel free to keep their release.
Otherwise enjoy our proper.
