Preferences are further detailed below. Exceptions to these guidelines may apply (see below for details).


=Video=
In selecting accepted formats for release, we go for the best quality possible, but we also try to accomodate lower-spec machines that might not be able to handle H.264 or HD content, and content that is compatible with DVD-burning. At the same time, in the interests of simplification, we are slowly cutting down on the number of formats we accept.


==Video 'food-chain'==
<pre><-- increasing rank</pre>
* <b>(Group A)</b> H.264 Bluray 1080p or equivalent quality
** <b>(Group B1)</b> H.264 Fansub 720p and below
** <b>(Group B2)</b> H.264 Dual-Audio (R1 single-audio rips accepted in this slot if no Dual-Audio available)
*** <b>(Group C)</b> Xvid/DivX (H.264 DTV rips accepted if no Xvid release available)
'''Note:''' Dual-audio release always replaces single-audio release ''of comparable quality''.


==Accepted releases==
 
Except under special circumstances (see below), we will only accept at most 4 releases:
-->
* 1 release from '''Group A'''
=Format Preferences=
* 2 releases from '''Group B'''
<!--
** 1) [Dual-Audio release] or [Single-Audio + R1-subtitles]
 
** 2) [Fansub release]
 
* 1 release from '''Group C'''

*TV Series
*Movies
*BD/DVD/TV Specials
*OVA/ONA (ONA goes under OVA)
*Live Action

*Groups A, B and C have 2 slots each, for the best available '''single-audio''' and '''multi-audio''' releases.
*If the best available release* happens to be multi-audio, only one slot will be used.
 
''* Releases are judged on video, audio and subtitles. A multi-audio release that is, '''in all three aspects''', comparable to or better than a single-audio release will displace it.''
 
===Accepted Releases===
 
Each video group will hold no more than 2 releases, one per slot (single-audio/multi-audio).
Under certain circumstances listed below, we may grant some releases under video group D:
 
* Very high bitrate content in Group B with no accepted releases in Group C
** A lower-bitrate option may be granted in Group D for lower-spec machines.
* A release with lower video quality, but has better subtitles than existing releases.
* Other notable exceptions, to be decided by staff.
** E.g. PSNR's HDTV release of GitS movie, which has video quite different from the filtered Blurays.
 
'''Note:''' Offers for a release might not be accepted if a better/preferred version is on the way.

==Exceptions to Guidelines==
====Exceptions====
The following exceptions apply:
 
<p style="padding-left: 15px;">The following exceptions apply:</p>
#HDTV/DVD rips are ''temporarily'' allowed if complete Bluray rips are more than a month away. These will be replaced once the Bluray release is uploaded.
#We're still thinking.
 
===Remuxing Guidelines===
 
Remuxing of audio and subtitle tracks from other groups is generally discouraged. Keep group releases intact as far as possible.
 
====Exceptions====
 
<p style="padding-left: 15px;">The following Remux exceptions apply:</p>
#We will accept remuxes if the available releases all fail terribly in one or more aspects (video, audio, subtitling, etc). We will not approve releases with audio from one group and video from another, just because "the audio track from one is somewhat better than the other".
#Remuxes that combine a HD video quality release with the english audio track of a lower video quality release will be considered only if there is no sign of a dual audio HD release appearing any time soon. The timing of the audio and subs must be spot on, we do not want some demux, remux, release crap.
##If any HD dual audio alternative exists (either 720p or higher) a remux will not be considered just because it is not available in all HD resolutions.
#Remuxes that combine the best tracks from different, but otherwise complete releases or leave a release as-is BUT add a significant improvement to it (addition of relevant notes or QCing the script) will be considered on a case-to-case basis.
 
 
'''NOTE:''' If allowed all re-muxed releases must have 'Remux' keyword and credit the groups used in suggested format:
* '''[Groups] [Title] [Episode number] [CRC]''' - source of the video (TV, DVD or Bluray) may be added as well, but is optional.
* '''[BBT-RMX] [Groups] [Title] [Episode number] [CRC]''' - alternative naming if the remux is intended specifically for BakaBT.
 
 
'''NOTE 2:''' To keep better track of our files even upon removal please update them in our [http://anidb.net/perl-bin/animedb.pl?show=group&gid=9030 AniDB entry].

====Exception 2====
===Audio Groupings===
Releases normally replaced by higher-ranked releases may instead be allowed to co-exist with or replace them if they have something that the higher-ranking offer does not, e.g.:
* better ''subjective'' video quality (Staff will decide based on comparison screenshots, video samples (if available), and/or user comments).
** Example: [http://www.BakaBT.com/torrent/144733/Ghost_in_the_Shell_(HDTV_720p_H264_DTS)_PSNR.html PSNR HDTV Ghost in the Shell] vs. [http://www.BakaBT.com/torrent/130601/Ghost_in_the_Shell_(Blu-Ray_720p_H264_DTS-ES)_THORA.html THORA Bluray Ghost in the Shell]
* Dual-audio vs Single-audio
* fansubbed translations vs official-[http://en.wikipedia.org/wiki/DVD_region_code#Region_codes_and_countries R1]/modified-R1 translations
* other noteworthy points (to be discussed in [http://forums.BakaBT.com/index.php?board=4.0 Uploaders' Forum] or in torrent comments)


====Exception 3====
*We only allow 2 versions of any OST album/compilation:
Older releases that do not fall under these guidelines (such as older, rarer [http://en.wikipedia.org/wiki/Divx DivX]/[http://en.wikipedia.org/wiki/Ogm OGM] releases) can be discussed in the [http://forums.BakaBT.com/index.php?board=4.0 Uploaders' Forum]. These rules do not apply in such cases.
<!-- #<font color="green">'''(Group A)''' [http://en.wikipedia.org/wiki/Lossless lossless], 24bit FLAC format</font>  -->

#<font color="#AAAA00">'''(Group C)''' [http://en.wikipedia.org/wiki/Lossy lossy], MP3 format.</font>


====Exception 4====
===Accepted Releases===
'''(Applies to Group B only)'''


In certain cases where the 720p Bluray torrent exceeds a certain size ''(cutoff filesize to be confirmed in time to come)'', a single-audio 'quality rip' of smaller filesize will be allowed alongside the Bluray rip (i.e. 3 releases accepted for Group B: Bluray, smaller 'quality release' and 'alternative release').
*Offers must be in one-file-per-track format.
* Example: Lupin III: Castle of Cagliostro - [http://www.BakaBT.com/torrent/142901/Lupin_III_The_Castle_of_Cagliostro_(1979)_720p_Bluray_x264_THORA.html THORA 720p, 4.4GB]; [http://www.BakaBT.com/torrent/129339/Lupin_III_The_Castle_of_Cagliostro_a4e.html a4e Dual-Audio, 1.35GB]; [http://www.BakaBT.com/torrent/141062/Lupin_III_The_Castle_of_Cagliostro_h264_ritchan.html ritchan DVD-rip, 1.80GB]
*All files in an album/compilation should match a single group (Audio Format). You may not have an MP3 file in an otherwise FLAC group release.
*Similarly do not mix formats.  
**i.e. FLAC: 24bit or 16bit
**i.e. MP3: 320kbps CBR or v0 VBR.
</div>
</div>
<!--


==Other Guidelines==
Re-muxing of audio and subtitle tracks from other groups is generally discouraged. We will accept remuxes if the available releases all fail terribly in one or more aspects (video, audio, subtitling, etc). In other words, we will not approve releases with audio from one group and video from another, just because "the audio track from one is somewhat better than the other". Keep group releases intact as far as possible.


=Manga & Printed Material=
We only allow 1 manga release (best available version) for each manga series, artbook, or other printed material.


=Soundtracks=
We only allow 2 versions of any OST album/compilation:
* 1 [http://en.wikipedia.org/wiki/Lossy lossy] release, in MP3 format
** Best quality possible, i.e. '''320kbps [http://wiki.hydrogenaudio.org/index.php?title=CBR CBR]''', or '''v0 [http://wiki.hydrogenaudio.org/index.php?title=VBR VBR]'''
* 1 [http://en.wikipedia.org/wiki/Lossless lossless] lossless release, in FLAC format
** All other lossless formats should be converted to FLAC before uploading.
** FLACs must be in one-file-per-track format.
* For [[How to make an offer#Parent torrents|parent-child torrent groupings]], lossless formats are preferred as parents over lossy formats, unless the lossy formats contain more albums or other torrent content.

Format Preferences
This is how we want our stuff packaged

We only accept complete, Anime/manga-related Series/Movies/OVAs/printed materials. We also allow Live Action adaptations (of anime/manga and related games/eroge/visual novels).
Not accepted are items specifically made for the American market.

Read the walkthrough to making a torrent offer if it is your first time making one. The Torrent Content Upload Guidelines cover what content is allowed to be uploaded here. In this section, we describe in detail how we want this content to be packaged.

If in doubt, remember our mantra: Quality over Quantity


Format Preferences

Video

In selecting accepted formats for release, we go for the best quality possible, but we also try to accommodate lower-spec machines that might not be able to handle high-bitrate content.

Video Types

  • TV Series
  • Movies
  • BD/DVD/TV Specials
  • OVA/ONA (ONA goes under OVA)
  • Live Action
  • Music Videos

Video Format

  • Codecs: Xvid, H.264/AVC, H.265/HEVC
  • Containers: AVI, MKV, MP4
  • Subtitles: Softsubs

Video Groupings

  1. (Group A) 1080p releases
  2. (Group B) 720p releases
  3. (Group C) SD (generally 576p and below)
  4. (Group D) Staff-approved exceptions
  • Groups A, B and C have 2 slots each, for the best available single-audio and multi-audio releases.
  • If the best available release* happens to be multi-audio, only one slot will be used.

* Releases are judged on video, audio and subtitles. A multi-audio release that is, in all three aspects, comparable to or better than a single-audio release will displace it.

Accepted Releases

Each video group will hold no more than 2 releases, one per slot (single-audio/multi-audio). Under certain circumstances listed below, we may grant some releases under video group D:

  • Very high bitrate content in Group B with no accepted releases in Group C
    • A lower-bitrate option may be granted in Group D for lower-spec machines.
  • A release with lower video quality, but has better subtitles than existing releases.
  • Other notable exceptions, to be decided by staff.
    • E.g. PSNR's HDTV release of GitS movie, which has video quite different from the filtered Blurays.

Note: Offers for a release might not be accepted if a better/preferred version is on the way.

Exceptions

The following exceptions apply:

  1. HDTV/DVD rips are temporarily allowed if complete Bluray rips are more than a month away. These will be replaced once the Bluray release is uploaded.
  2. We're still thinking.

Remuxing Guidelines

Remuxing of audio and subtitle tracks from other groups is generally discouraged. Keep group releases intact as far as possible.

Exceptions

The following Remux exceptions apply:

  1. We will accept remuxes if the available releases all fail terribly in one or more aspects (video, audio, subtitling, etc). We will not approve releases with audio from one group and video from another, just because "the audio track from one is somewhat better than the other".
  2. Remuxes that combine a HD video quality release with the english audio track of a lower video quality release will be considered only if there is no sign of a dual audio HD release appearing any time soon. The timing of the audio and subs must be spot on, we do not want some demux, remux, release crap.
    1. If any HD dual audio alternative exists (either 720p or higher) a remux will not be considered just because it is not available in all HD resolutions.
  3. Remuxes that combine the best tracks from different, but otherwise complete releases or leave a release as-is BUT add a significant improvement to it (addition of relevant notes or QCing the script) will be considered on a case-to-case basis.


NOTE: If allowed all re-muxed releases must have 'Remux' keyword and credit the groups used in suggested format:

  • [Groups] [Title] [Episode number] [CRC] - source of the video (TV, DVD or Bluray) may be added as well, but is optional.
  • [BBT-RMX] [Groups] [Title] [Episode number] [CRC] - alternative naming if the remux is intended specifically for BakaBT.


NOTE 2: To keep better track of our files even upon removal please update them in our AniDB entry.
