Snow?

Postby Gepetto » Sun Aug 20, 2006 2:34 pm

I just started reading about x264 encoding and downloaded MeGUI. It has an option for encoding with a certain "snow" codec, and not even the wikipedia had barely anything more than a "dictionary entry" of the term. What is this codec, and how does it compare to the other ones out there?

Snow is an experimental wavelet based codec. To the best of my knowledge, it does not conform to any standards, but is a completely original design. I haven't followed its developement closely, but I *think* its gets quality/filesize around similar or maybe better than xvid, but not as good as h.264.

Do to it's experimental and non-standard nature, it should not be used for anything you want to distribute.

Thank you. Distribution is what I mwas wondering about. But if it's still in experimental stage, does it mean it can come to surpass x264?

Just like Zarx has said, Snow is a public domain wavelet encoder. At the moment I believe the quality is comparable to XviD; but pengvado who codes for x264 and Snow says that Snow can go further than x264. That is mainly due to the fact of it being wavelet based, you immediately remove some of the "blocking" artifacts associated with codecs such as MPEG-4 ASP (DivX/XviD).

That is something impressive by no means; but to agree with Zarxrax it's probably best to stick with x264 since H.264 is an industry standard. The same applies for MKV vs MP4, MKV is more flexible than MP4 but it is not standard.

Having said that, MP4 supports all MPEG codecs so you only miss out on stuff like Vorbis or WMV video (not a big loss IMO since AAC is as good as Vorbis, and sometimes better).

Information assimilated. Thank you.
