MainConcept is proud to announce the immediate availability of our H.264 Encoder Preview Version for Microsoft® Windows®! Although not yet optimized for speed, this free demo will enable you to sample the quality of our newest codec. H.264 AVC (Advanced Video Coding), also known as MPEG-4 Part 10, is an exciting new standard which offers many advantages and has the potential to replace existing standards.Our H.264 Encoder Preview Version also includes our H.264 Decoder, enabling you to play H.264 files in Windows Media Player and other compatible programs. NOTE: This demo version places a watermark on encoded material.
but the quality seems to be strongly fluctuating, meaning it seems that sometimes the picture is blurry, than sharp again, than blurry, with blocks sometimes showing up in between... (maybe thats a decoding issue?)
AFAIK this technology preview is only able to use CBR which would explain the fluctuating quality.
How fast is encoding/decoding (compared to xvid)?
inloop filtering?for filtering we have avs and vdub,no need for codec to do filtering....
so,what's the difference?1-vdub or avs cleaned video;less noise in I-frame=less noise in subsequent P's....2-h264's inloop;codec denoises,result is the same
this sort of filtering is a BAD thing and shows that desperate measures are employed;this just blurs the image
the trouble is this;i doubt wmv9(or h264,if bulletproof is right(on 1mbit),and i think he is) has adaptive filtering(ie. filter less as bitrate increases)...that's why normal mpeg4 might even win on higher bitrates...it just might...and on lower bitrates..well,there's always ffdshow and addnoise....(as i said,if there's a confirmation that this encoder can load avs,i'll try it against mpeg4...i already tried wmv9 and i didn't took that encoding path..it's 2x(or more) slower while being 10-20% better than mpeg4 on lo bitrates...and better here means that it blocks less,but also has less detail....i rather use ffdshow to compensate...)[snip]this sort of filtering is a BAD thing and shows that desperate measures are employed;this just blurs the image (few nice illustration shots in this pdf....both blocked and filtered images look like crap;one is full of blocks,and another is blurred like freakin' rv9!) (perhaps this is the link to get pdf'shttp://www.vcodex.fsnet.co.uk/h264.html )
bonzi,does that look like key-frame "pumping"?(ie. like overcompressed KF's?)can you post few subsequent screenshots?jpeg will do...and also,did you load avs or?but i thought whol epoint of new codecs is going DOWN with the bitrate,and not up(but ok,this is too early time to say anything about h264)
Has anyone tried to play these files using mplayer?
i believe i'm not mistaking if i say that this technology is not mature at all,and it needs more time to become of any use....(needs faster encoding,faster decoding,compatibility etc.)i'll leave it at that for now.....
(simply imagine how divx5 and xvid performed some years ago)
