This document is designed to resolve problems with dupes, propers, REAL_PROPERS, etc.. 
and to ensure that only quality releases are released to the MV scene. The following 
groups have agreed to follow these guidelines:

      a) Dirname/Filename
      b) Logos
      c) Concerts & Live Performances
      d) NFO

3) Propers and dupes

1) Encoding
     Four formats will be allowed: XViD, DIVX, SVCD and VCD.
     - This means that any other format, such as:
     will not be allowed. If you must, keep them INTERNAL.

VCD Audio:         MPEG-1 Layer 2 44.1KHz 224kbps
                   Replacing audio on VCD rips is RECOMMENDED,
                   but not required.

VCD Video:         - PAL, 1150kbps CBR, 352x288, 25 fps.
                   - NTSC, 1150kbps CBR, 352x240, 29.970 fps.
                   - NTSC-FILM, 1150kbps CBR, 352x240, 23.967 fps. (via IVTC)

SVCD Audio:          Audio must be replaced on all SVCD music videos.
                     Replacement audio must be from a CD, or from a high
                     bitrate MP3 (192kbps+) ripped from a CD. All
                     video soundeffects must be inserted into the replac-
                     ement audio

                     - If replacement audio *DOES NOT EXIST* for videos older than 1998,
                       then you can release with normalised tv audio, AND, IF

                     - Vinyl ripped MP3s are not to be used. Replacing
                       less-than-cd-quality with less-than-cd-quality is

                     - Use uncensored audio. If you use censored audio,
                       prepare to be propered.

                     - Live rips (concerts, performances) use normalised audio
                       from source. If source is 48KHz, downsample to 44.1KHz.

SVCD Video:          - PAL, Should be inverse 2:2 pulldown manually, if possible.
                       (This is also known as manual-deinterlace). If this isn't
                       possible on a regular vid the nfo MUST state why.

                     - NTSC, Should be inverse 3:2 pulldown manually, if possible.
                       (This is also known as IVTC).
                       If 3:2 pulldown is not possible, then inverse 2:2 pulldown 
                       manually, if possible.
                       (This is also known as manual-deinterlace)
                       If none of the above methods is possible the nfo MUST state why.

                     - Interlaced videos will not be allowed.

                     - Video and audio bitrate MUST be within SVCD standard.

                     - For maximum player compatibility, it is STRONGLY
                       RECOMMENDED that the video bitrate does not exceed
                       2496 kbps. - SVCD rips must not be ripped from VHS or SVHS source,
                       due to the sub-SVCD specs of both formats.
                     - VHS resolution (analogue) approx 240 lines of resolution.
                     - SVHS resolution (analogue) approx 400 lines of resolution.
                     - VCD resolution = 352x240(NTSC), 352x288(PAL)
                     - SVCD resolution = 480x480(NTSC), 480x576(PAL)

                     - VHS/SVHS is only sufficient for VCD rips. SVCD rips
                       from VHS/SVHS must be kept INTERNAL.

XViD Video:          [standard Video]
                     - Allowed codecs: Xvid 1.1+ or Divx6.1 +
                     - Upsampling the horizontal resolution to maintain the vertical 
                       resolution is allowed.
                     - Upsampling both the horizontal and vertical resolution from 
                       the source video is not allowed.
                     - The width and the height of the video have to be a multiple of 16.
                     - Maximum (PAL ) resolution is 720x576 @ 25fps
                     - Maximum (NTSC) resolution is 720x480 @ 30fps
                     - All videos MUST be manually deinterlaced / ivtc'd (if possible).
                     - Maximum allowed average bitrate is 4000 kbps.
                     - Maximum peak bitrate during any 1 second of video is 8000 kbps.
                     - Interlaced encoding is NOT allowed.
                     - GMC and QPEL are NOT allowed.
                     - AVI pixel shape must be square.
                     - Only the MPEG and H.263 quantization matrices are alowed.
                     - No packed bitstream.
                     - Key frames must be inserted every 10 seconds or less.
                     - It is strongly recommended videos should encoded with 1 pass using
                       a target quantizer setting of between 3 and 4 inclusive.
                     - The DRF of the video should be below 8 inclusive.
                     - For concerts or other performances which are long enough, the 
                       video must be made to fit on 1 or 2 cds (700meg) whilst still 
                       obaying the rules above, except for the minimum DRF. 
                       A 2 pass encode must always be used for this.

                     [High Definition Video]
                     - Source must have a horizontal resolution greater than 720 for 
                       progressive video, and a horizontal resolution greater than 1440 
                       for interlaced video.
                     - Maximum resolution is 1280x720 @ 30fps
                     - Progressive rips must be encoded at 1280x720 unless broadcast at
                       a lower  resolution.
                     - Interlaced sources must be encoded at half resolution and must be 
                       deinterlaced by discarding the 2nd field (even/odd field deinterlace)
                       (eg 1080i to be encoded at 960x544)
                     - Maximum allowed bitrate is 4000kbps.
                     - Maximum peak bitrate during any 1 second of video is 20000 kbps.

                     Cropping and Aspect ratio 

                     - Letterboxed videos should be cropped to remove the black bars.
                     - There is one exception to this: when there's an overlaping logo common
                       sense should be used to decide whether to crop the entire black bar 
                       and thus cropping half of the logo, or cropping it completely. 
                       Propering on no or half cropped overlapping logos is NOT allowed.
                     - Some videos contain variable aspect ratios. Crop as to not remove any 
                       of the picture throughout the video.
                     - If black bars are still present in the video after cropping (due to 
                       permanent logos etc) they must be of equal size.
                     - Encodes must be within 5% of the original aspect ratio.
                     - Calculating AR % error: (Release - Original AR)/Original AR x 100

XViD Audio:          - Can be MP2, MP3 or AC3
                     - MP2 must be used if no audio replacement exists and if the audio 
                       source contains MP2 audio. The audio can be normalised if the 
                       normalisation does not involve re-encoding the audio.
                     - MP2 audio must be interleaved every frame with 500ms preloaded.
                     - AC3 allowed only if it is 384 kbit+ and from a DVD/HDTV source.
                     - AC3 must be untouched.
                     - AC3 pre load 64/96ms of audio and interleave every 64/96ms.
                     - MP3 audio must be used as audio replacement on normal videos. 
                       It must have a average minimum bit rate of 160kbit and must be 
                       either 44.1khz or 48khz.
                     - CBR audio is prefered, however VBR audio will not be nuked. CBR audio 
                       is required for maximum hardware and software player compatability.
                     - MP3 encodes must always be done with LAME 
                       (APS (--alt-preset standard) prefered for VBR)
                     - MP3 audio must be interleaved every frame with 500ms preloaded.
                     - Use uncensored audio
                     - Sound effects contained in the source audio must be inserted into the 
                       replacement audio if missing.
                     - If replacement audio *DOES NOT EXIST* for videos older than 1998, then 
                       you can release with normalised tv audio, AND, IF REPLACEMENT AUDIO 
                       BECOMES AVAILABLE,it can be PROPERED.
                     - Vinyl ripped MP3s are not to be used. Replacing less-than-cd-quality 
                       with less-than-cd-quality is pointless.

2) Releasing
     2a) Dirname/filename

          - Directory name is decided by the group. However, the following naming
          scheme is STRONGLY RECOMMENDED:




          - SFV and NFO are required.

          - The standard extension is .mpg for both VCD and SVCD releases. However,
          it doesn't matter, so groups decide to use .mpg or .m2v as extension.

     2b) Logos
          - Including an intro/outro is NOT RECOMMENDED. Advertisements in your
          videos is not what the MV scene is about... if you must spam, then
          do it your NFO file. However, intro/outro will not be banned, and
          propering a video with a logo will not be permitted.

          - Watermarking on videos is NOT ALLOWED. This is the same situation as
          intro/outro - nobody wants to stare at your spam while watching your
          rips. It's already bad enough that tv stations do it. Videos with
          watermarks can be propered.

          - For letterboxed videos, covering a TV station logo that is entirely
          in the letterbox is RECOMMENDED. However, propering because of
          tv-station-not-covered will not be permitted.

     2c) Concerts and Live Performances
          - Concerts involving one artist must be released as one release.
          This means, for example, that if you rip a concert of Linkin Park
          at the Royal Albert Hall, you CANNOT release each song as a release.

          - You should include the main introduction and any other introductions
          between songs, as the point in ripping a concert is to have a COMPLETE
          copy of the concert.

          - The ripper decides to rip as separate tracks or as full CDs.

          - If you rip as separate tracks, DO NOT PUT A LOGO ON EACH TRACK.
          Single-tracks ripped concerts should be packaged in ONE release,
          similar to a mp3 album:


          - If you rip as full CDs, it is recommended that you use multipass VBR
          to make it fit evenly on one or more CDs. Also package it as a BIN/CUE,
          and release it the same way VCDs are: 15mb rars, and a 1 minute sample:


          - Non-concert live performances with more than one song, such as those
          on TOTP, awards shows, etc. should be released as individual videos
          with any intermediate footage (interviews, presentations, etc.) cut
          out. Also, include the date and the name of the show in the dirname.

          - COMMERCIALS (such as Britney Spears' Pepsi) are not music videos, so
          they will not be allowed. Keep non music video rips INTERNAL.

     2d) NFO
          - Your NFO should contain:
            - Artist and Title
            - Format (VCD/SVCD, and PAL/NTSC/NTSC-FILM)
            - Video source
            - Audio source
            - Deinterlace type
            - Size
            - Genre (This is nice for sites with scripts that search NFOs for genre)
            - Video Year
            - Live videos MUST include the show it is from and the date it was aired.
            - If you are propering, you MUST include the reason for proper,
            and the name/date of the release being propered.

          - Other useful information to include in your NFO, optionally, is:
            - Length in min:sec
            - Bitrate of video and audio streams
            - Album name
            - Description of video
            - Fullscreen or Letterbox (FS or WS)
            - Source (Name of DVD or name of TV station)

3) Propers and Dupes

     - Propering because of SLIGHT quality increase is not acceptable. If the original
       rip was very bad, then proper, but un-needed propers will be nuked!

     - PAL & NTSC
       - Releases of lower quality are dupes of higher quality, as decided by
         the following list, which is in order of lowest quality to highest:


       - Native: This means progressive.
       - NTSC produced video is native to NTSC broadcasts, and PAL
         produced video is native to PAL broadcasts. Native NTSC
         broadcast means IVTC-able NTSC or progressive NTSC.
         Native PAL means progressive PAL.

       - Convert: This also means deinterlaced.
       - A PAL produced video, broadcast in NTSC, is converted before
         it's broadcasted. A NTSC produced video is converted to PAL
         before it's broadcasted. These converts cannot be reversed
         to progressive, and must be deinterlaced.

         Hence, it is not a good idea to release pal-ntsc converts of top 50 videos,
         because a native rip will be released.
       - Widescreen/fullscreen dupes will not be allowed. Keep WS/FS dupes INTERNAL.

       - The following are reasons for you to release a PROPER:
            - Desync
            - Incomplete
            - Improper inverse 3:2 or 2:2 pulldown
            - Lack of inverse 3:2 or 2:2 pulldown (if possible)
            - Incorrect Aspect Ratio
            - Out-of-spec rips
            - Massive frame drops
            - Very bad quality (includes low bitrate on high motion videos)
            - Rips without replaced audio (Concerts/performances excluded)
            - Poor quality replacement audio
            - Censored replacement audio
            - Missing more than 1 SFX (propers due to 1 SFX missing not needed)
            - Native video with correct picture aspect is broadcasted
            - Logo included more than once in a concert release
            - No manual deinterlacing/IVTC'ing when possible
            - Watermarked video
            - Bad cropping
            - Improper multiplexing (such as underflowed audio)

       - It is vitally important that you state which release you are propering
         and your reasons in your nfo, and as well make sure to put -proper- in
         your dirname.

       - It is STRONGLY RECOMMENDED that you demux SVCD/VCD with M2 edit, and remux 
         with bbmpeg, to avoid improper multiplexing errors.

       - No propering of releases previous to MV COUNCIL will be allowed.
         If you want to release a better version of an OLD video, keep it INTERNAL !

       - No dupes based on resolution aspect ratio or video profile.
