To be completely honest, my humble opinion is that AQ is far from always required, or even useful. But for what Mentar is talking about, I agree; it should be used for high-bitrate/high-quality encodes.

Guys, I find myself in a position somewhere between puzzlement and amusement here. This "disadvantage" which "raises" quants for constant-quant/quality encodes is a logical consequence and pretty much exactly what I want. It's nothing you should list as "buuuuut this is the downside" as if that wasn't clear to begin with.
Now before you all look at me perplexed, think of it this way: The current x264 bitrate bias emphasizes normal "bright" and well-contrasted spots on the expense of darker ones with less details. Of course you can make the encoder decision to say "it's sucky TV raws anyway, screw these spots", blur them into oblivion and just accept their degradation, and use the bitrate _stolen_ from there to polish up the rest of the frame more. Heck, there's even some logic to that, because most ASP-based TV raws already have these kind of dark spots damaged to begin with, so "preserving" it sometimes even acts as preserving "weaknesses". But still, it's a conscious decision to abandon the trouble spots. In other words, it's "taken from the needy, given to the greedy", while the negative impacts of further screwing over the needy are mollified by smoothing it over. And this is what I (personally) dislike in many (not all, but many) 140-and-smaller encodes: While the contrasts tend to be clean with little ringing, the overall picture tends to be very very soft, and darker areas look strangely unicolor, with occasional big macroblocks stirred into the soup. Now I won't contest that this is a perfectly valid way to arrange the picture and entirely up to the encoder, but... not my cup of tea, sorry ^_^; Once we reach the DVD-encode bitrates, it seems that we've reached a consensus that the bits should be sufficient to allow for AQ cleanups. About the medium-range (170) I guess we'll still have to fence it out |

There is a pattern in our releases, at first the download rate of x264:XviD is roughly 1:1, then the number x264 drops and in longer term in fall back to about 1:2.5. I think it has something to do with the seeds, many people don't like to download when the torrent seems slow. So if people batch the h264 but not xvid. The ratio should rise. Talking about the double release, I think it is getting in the way. While a normal XviD encode takes 20-60 minutes, I am using 2-4 hours to encode x264. Counting the upload time, it is often a next day release. |

On the first, those who care more about the file the recieve are more willing to spend time & effort in getting better files to work. On the second, most h264 HD releases that come from groups also doing a SD xvid release add a HD into the filename. The number of people who wouldn't see any single one of: filesize, HD in name, h264 in name, mkv/mp4 extension and confuse the download with a SD xvid gets what they deserve |

Indeed. I don't think I've seen any groups that release in both XviD and h.264 and do not give some sort of hint (ie. tagging or commenting) as to what to expect.
Similarly for the SD / HD argument. Typically if it's unstated, it can be assumed to be SD. Even without stating SD / HD, the group may at least state a resolution from which such information can be discerned. I don't recall seeing HDTV releases without a tag stating such, but I suppose there is the odd case when a group may not (or forgot). Even then, the file size should clue people in. I believe that if those who download truly want to be conscious about what they're getting, they should be paying more attention rather than haphazardly clicking links and confirming (and even then there's still X amount of time between when you open the torrent and complete it) at first notice of the series title. |

wazzup@teh homies! from a leecher prespective what we want is quality tempered with size when blu ray dvd's become cheap and common then it wont be as important, but ive found that 233MB encodes are easy to swallow as are 175MB and there is no reason to shrink the encode smaller than that. i would love to see true hd encodes or higherdef encodes, but filesizes around a gig scare me a bit. ive a few TB of the current size encodes and i just dont know if i could go back to 4 eps per disk >_< also ive noticed that some groups when doing an mkv dont force the subs track on ~_~ if someone [ i know its a bit off topic but they are often 264 if that makes u feel better ] wouldnt mind telling me how to do so i could quite nicely correct said groups and yeah.... anyway keep up the good work... what a thread... |

Shinsen released a 1920x1080p fansub at 350mb, and prior to that there was a 708mb one which was basically the japanese raw +softsubs released on a private hd tracker.

The few complaints about it on the doom9 board seem to mostly say "we can decide what's best for ourselves and anyway there is no easy way to do h264 encoding without the vfw".
To which I say "if you really feel you need avi output it's a simple matter with avc2avi, and I think "familiar" would be a better term, because programs like megui with its inbuilt profile system require far less codec configuration". I would finish with an insult about their mothers and, if required, a last retort of "stop hosing". The one thing that I'm worried about is the vfw lovers just not upgrading their x264. Maybe it would have been better to subtly break the vfw over a number of versions in order to maximise confusion and sow dissent within the evil enemies ranks. </serious post> (</html jokes>) |
