Séries TV: la scène délaisse le conteneur MP4 et passe au MKV

Quatre ans après le passage du codec XviD au codec x264, voici que la “scene” change de nouveau les règles du jeu : les fichiers SD et HD seront maintenant en .MKV (Matroska) et non plus en .MP4 pour les séries TV.

Depuis le 10 avril 2016, les nouvelles règles sont entrées en vigueur : si le codec x264 est bien gardé, le conteneur va lui changer – finis les fichiers portant l’extension MP4, ce seront maintenant des fichiers MKV (Matroska) que l’on pourra trouver sur la toile.

Les raisons du changement de conteneur

Concrètement, la scène justifie ce changement de conteneur avec les évolutions des standards et de la qualité des encodages.

Dans l’introduction des règles, on peut lire que “depuis la dernière révision du document qui date de 2012, TV-X264-SD a évolué et est devenu une section majeure à laquelle beaucoup de gens contribuent et dont beaucoup dépendent. Cette nouvelle révision vise à mettre à jour les standards pour 2016 et après.”

Ces règles sont à l’intention des groupes de la scène uniquement (qui s’échangent les fichiers entre eux via des topsites) mais la plupart des fichiers finiront entre les mains du grand public, partagés sur des sites publics.

Cela signifie donc que ces changements vont impacter des centaines de millions de personnes à travers le monde, indirectement, par simple effet domino.

Les règles sont très exhaustives et abordent tous les aspects techniques de l’encodage des fichiers : normes audio, vidéo, formats, sous-titres… jusqu’au nom des tags des fichiers mais ce qui importe avec la mouture 2016 est la partie concernant le conteneur.

Règles 2016 : the SD TV x264 Releasing Standards 2016

Voici les règles 2016 concernant les releases en SD:


[ Intro ]
Since the last revision of this document in 2012, TV-X264-SD has grown and become a major section that many people contribute to and depend on. This new revision aims to update the standards from 2012 to standards suitable for 2016 and the future. Adding clarity and patching loopholes to once again allow for consistent and quality releases, which was the aim of this standard back in 2012.

Compliance with this document is optional as of its pre date, and mandatory as of 2016-04-10 00:00:00 UTC (1460246400 Unix time).

1) [ HDTV Sources ]
    1.1) HDTV is considered as a high definition natively recorded transport stream.
    1.2) HDTV sources must not be upscaled, see section 2.
    1.3) Providers which downscale 1080i to 720p (e.g. BellTV) are not allowed.

2) [ PDTV & DSR Sources ]
    2.1) PDTV is considered as a 576i/576p natively recorded transport stream.
    2.2) DSR is considered as a 480i/480p natively recorded transport stream.

3) [ AHDTV & APDTV & ADSR Sources ]
    3.1) AHDTV, APDTV and ADSR are considered as captured streams from the analog output (e.g. Component, DVI, HDMI) of a set-top box.
    3.2) Captures must be done at the native broadcast format of the source.
        3.2.1) Captures from devices which are unable to output a native format must be restored to the original framerate.
        3.2.2) If captures cannot be completely restored to their native framerate, such as a single dupe frame every 1000 or blended/ghost frames due to mangling from the set-top box or capture device, this is considered a technical flaw.

4) [ Codec ]
    4.1) Video must be H.264/MPEG-4 AVC encoded with x264 8-bit.
        4.1.1) Custom builds of x264 (e.g. x264-tMod, x264-kMod) are allowed and must be based off the x264 codebase.
    4.2) x264 headers must remain intact and must not be modified or removed.
    4.3) x264 must be kept up to date, with a maximum allowance, or grace period, of 60 days before groups are required to update to the latest revision.
        4.3.1) The official x264 git repository is the only reference for determining the current revision: http://git.videolan.org/?p=x264.git;a=summary
        4.3.2) The 60 day grace period must only be applied at pre time, not the tagged encoded date.
        4.3.3) The grace period is only applicable to the revision preceding the latest update and does not reset active grace periods of preceding revisions.
            e.g. 2016-01-01: Revision A is used.
                 2016-01-02: Revision B is committed, 60-day grace period begins for revision A.
                 2016-01-05: Revision C is committed, 60-day grace period begins for revision B.
                 2016-03-02: Revision A is no longer allowed, Revision B or C may be used.
                 2016-03-05: Revision B is no longer allowed, Revision C must be used.
    4.4) Constant Rate Factor (--crf) must be used.
        4.4.1) CRF values below 19 and above 24 are never allowed.
        4.4.2) Justification must be listed in the NFO for the use of non-standard CRF values.
   Groups are not required to follow non-standard CRF values used by another group.
   It is suggested that if the average video bitrate exceeds 1500kb/s, a higher CRF value should be chosen, when possible.
    4.5) Standard CRF values are as follows:
        │ Compressibility │  CRF  │ General Examples                          │
        │ High            │ 19-20 │ Scripted, Talk Shows, Animation, Stand-Up │
        │ Medium          │ 21-22 │ Documentary, Reality, Variety, Poker      │
        │ Low             │ 23-24 │ Sports, Awards, Live Events               │
    4.6) Settings cannot go below what is specified by preset (--preset) 'slow'.
        e.g. --subme 7 or --me hex are not allowed.
    4.7) Level (--level) must be '3.1'.
    4.8) Colour matrix (--colormatrix) must be set.
        4.8.1) 'bt709' must be used for encodes from HDTV or AHDTV sources.
        4.8.2) Source specification must be used for PDTV, APDTV, DSR, ADSR sources.
   'undef' must be used if not specified by the source.  
    4.9) Colour space (--output-csp) must be 'i420' (4:2:0).
    4.10) Sample aspect ratio (--sar) must be '1:1' (square).
    4.11) Deblocking (--deblock) must be used. Values used are left to the discretion of the group.
    4.12) Keyframe interval (--keyint) must be at least 200, and at most 300.
        4.12.1) It is recommended to let x264 decide which value to use, but 10*framerate is a good guideline (e.g. Film=240, PAL=250, NTSC=300).
        4.12.2) For 50 or 60 FPS content, the maximum keyframe interval must be at least 200, and at most 600.
    4.13) Minimum GOP length (--minkeyint) must be 30 or less.
        4.13.1) It is recommended to let x264 decide which value to use, but 1*framerate is a good guideline (e.g. Film=24, PAL=25, NTSC=30).
        4.13.2) For 50 or 60 FPS content, values of 60 or less must be used for the minimum GOP length.
    4.14) Custom matrices are not allowed.
    4.15) Zones (--zones) are not allowed.
    4.16) x264 parameters must not vary within a release.

    4.18) Suggested command line: x264 --crf ## --preset slow --level 3.1 --colormatrix ## --output out.mkv in.avs

5) [ Video / Resolution ]
    5.1) Resolution must be mod 2.
    5.2) Upscaling is not allowed.
    5.3) Adding borders is not allowed.
    5.4) Multiple video tracks are not allowed.
    5.5) English spoken titles with foreign overlays, not intended by content creators (e.g. locations, on-screen text shown in another language) are not allowed, use INTERNAL.
        5.5.1) This does not apply to opening titles or credits, but to relevant show content only.
    5.6) Non-English spoken titles with hardcoded English subtitles must be tagged as SUBBED.
        5.6.1) English spoken titles with hardcoded English subtitles present for English spoken scenes must be tagged as SUBBED.
        5.6.2) English spoken titles with hardcoded Non-English subtitles present for English spoken scenes are not allowed, use INTERNAL.
        5.6.3) Hardcoded subtitles added by content creators are exempt (e.g. Alien hardsubs, drunk talk hardsubs, hardsubs due to muffled mic).
    5.7) Dupes based on resolution are not allowed.
        5.7.1) Except in situations of releases with a different aspect ratio. The relevant tag must be used, and the reason mentioned in the NFO.
        5.7.2) Releases which contain at least an additional 20 pixels worth of video on any side are not considered dupes. These releases must be tagged as WS or OM (open matte) and not proper, and the original release must not be nuked.
    5.8) Black borders and anything (e.g. coloured borders, duplicate lines, dirty pixels, full-time tickers) that is not part of the video must be cropped.
        5.8.1) Retention or removal of faded edges is left to the discretion of the group. Inclusion of faded edges is not a technical flaw, and cannot be propered.
   Faded edges refer to a line of pixels which are of similar appearance to pixels' parallel to the video frame.
        5.8.2) In the case of varying aspect ratios throughout the video, cropping must be done to the most common frame size (e.g. primary view of the pitch during sports, studio view during talk shows).
        5.8.3) Cropping of letterboxed sources with hardcoded subtitles positioned within the black borders is left to the discretion of the group. Video may be left uncropped or cropped evenly both top and bottom to the widest frame without removing any subtitles.
   Cropping out hardcoded subtitles entirely is allowed, only when they are not required, leaving any trace of subtitles or over-cropping actual picture to remove subtitles is considered to be a technical flaw.
        5.8.4) Video may be over or under cropped by a maximum of 1px per side. Over or under cropping by more than 1px per side is considered a technical flaw.
    5.9) HDTV and PDTV sources with a greater than 720px width after crop must be resized to 720px width and a height which maintains a valid AR.
    5.10) PDTV sources must be cropped and resized to fit within a maximum resolution of:
        5.10.1) 720x for sources with a width between 720-705px (inclusive) after crop, only the height may resized to maintain a valid AR.
            e.g. 720x576 --> Crop(2,0,-2,-0) --> 716x576 (non-anamorphic) --> 716x404 (anamorphic)
        5.10.2) 704x528 for sources with a width of 704px or less after crop.
            e.g. 704x576 --> Crop(0,4,-0,-4) --> 704x568 (non-anamorphic) --> 704x392 (anamorphic)
                 544x576 --> Crop(4,0,-4,0) --> 536x576 (non-anamorphic) --> 702x386 (anamorphic)
    5.11) DSR sources must be cropped and resized to fit within a maximum resolution of:
        5.11.1) 720x for sources with a width greater than 720px after crop, only the height may resized to maintain a valid AR.
            e.g. 853x480 --> Crop(0,2,-0,-0) --> 853x478 --> 720x404
        5.11.2) 640x for sources with a width between 720-641px (inclusive) after crop, only the height may resized to maintain a valid AR.
            e.g. 720x480 --> Crop(8,2,-16,-0) --> 696x478 (non-anamorphic) --> 616x478 (anamorphic)
        5.11.3) 640x480 for sources with a width of 640x or less after crop.
            e.g. 528x480 --> Crop(0,56,-0,-60) --> 528x364 (non-anamorphic) --> 640x364 (anamorphic)
    5.12) Resized video must be within 0.5% of the original aspect ratio.
        Original AR = (SourceWidth û [CropLeft + CropRight]) / (SourceHeight û [CropTop + CropBottom])
        Release AR = EncodeWidth / EncodedHeight
        AR Error % = [(Original AR û Release AR) / Original AR] * 100

        Target resolution when resizing to maintain mod2 and reduce AR error:
        TargetHeight = TargetWidth / [(SourceWidth û [CropLeft + CropRight]) / (SourceHeight û [CropTop + CropBottom])]
        The correct mod 2 value can also be calculated from the ceiling of TargetHeight if the value is odd, and the floor of TargetHeight if the value is even.

6) [ Filters ]
    6.1) IVTC or deinterlacing must be applied as required.
    6.2) Only smart deinterlacers, such as Yadif or QTGMC, must be used.
        6.2.1) FieldDeinterlace must not be used for deinterlacing.
    6.3) Only accurate field matching filters, such as TIVTC or Decomb, must be used for inverse telecining (IVTC).
        6.3.1) Filters included in MEncoder, MJPEG tools, libav, libavcodec or FFmpeg must not be used for IVTC.
        6.3.2) Deinterlacing filters must not be applied to telecined sources as a method of inverse telecine.
    6.4) Only sharp resizers, such as Spline36Resize, BlackmanResize or LanczosResize/Lanczos4Resize, must be used.
        6.4.1) Simple resizers, such as Bicubic, PointResize or Simple, are not allowed.

7) [ Framerate ]
    7.1) Constant frame rate (CFR) must be used.
        7.1.1) Variable frame rate (VFR) methods are not allowed.
    7.2) True 50 / 60 FPS video must be released at 50 / 60 FPS. True 25 / 30 FPS video released at 50 / 60 FPS is not allowed and considered a technical flaw.
        7.2.1) Failure to apply a deinterlacer with bobbing enabled (e.g. QTGMC, Yadif(mode=1)) to double framerate (bob) 25i / 30i video back to true 50 / 60 FPS, is considered a technical flaw.
        7.2.2) In cases of varying framerates of 25 / 30 FPS and true 50 / 60 FPS, the framerate of the main feature must be used (e.g. studio for talk shows, game coverage for sports).
        7.2.3) In rare situations, 25 / 50 FPS sources must be restored to 24 or 30 FPS.
        7.2.4) In rare situations, 30 / 60 FPS sources must be restored to 25 FPS.
    7.3) Sources which contain footage at varying FPS throughout (hybrid sources) and may or may not require IVTC is left to the discretion of the group. The NFO must list a reason as to the final decision.
        7.3.1) It is assumed that the majority of a title contains enough unique frames at 30,000/1,001 FPS to warrant a higher framerate. If it can be proven IVTC/decimating does not result in any loss of unique frames, this is considered a technical flaw.
    7.4) Native and converted framerates refers to the standard in which the video was produced.
        7.4.1) NTSC produced video is native to NTSC.
        7.4.2) PAL produced video is native to PAL.
        7.4.3) NTSC produced video that is broadcast in PAL is considered as converted video.
        7.4.4) PAL produced video that is broadcast in NTSC is considered as converted video.
    7.5) Converted video that has significant abnormalities (e.g. blended frames, jerky playback due to missing or duplicate frames) due to the conversion and cannot be reversed to the native format must be tagged as CONVERT.
        7.5.1) Converted video which does not have significant abnormalities do not require the CONVERT tag and must not be nuked for the conversion.
    7.6) Dupes based on framerate are not allowed, use INTERNAL.

8) [ Audio ]
    8.1) Segmented encoding is not allowed.
    8.2) VBR AAC LC (Low Complexity) must be used.
        8.2.1) Apple/QAAC, FDK-AAC or Nero must be used.
   Any other AAC encoders (e.g. FFmpeg, FAAC, MEncoder) are not allowed.
        8.2.2) Quality based VBR encoding must be used, targeted or constrained VBR must not be used. Only the following methods are allowed (in order of preference):
   QAAC: --tvbr 82 --quality 2
   FDK-AAC: --bitrate-mode 4 --profile 2
   Nero: -q 0.4
        8.2.3) AAC audio must be normalised to the maximum gain. Normalisation must be a complete 2-pass method. No pre-defined values or estimations of maximum gain is allowed. Only the following normalisation methods are allowed (in order of preference):
   eac3to: ûnormalize
   sox: --norm
   QAAC: --normalize
        8.2.4) Any existing normalisation values such as dialnorm in AC3 files, must be stripped prior to applying normalisation.
            e.g. Decoding with eac3to: do not enable -keepDialnorm
                 Decoding with ffmpeg: enable -drc_scale 0
        8.2.5) Audio with more than 2 channels must be down-mixed to stereo.
        8.2.6) Audio must not be resampled. Audio must be kept in the original format as the source (e.g. 48KHz for 48KHz sources).
        8.2.7) Audio which is already presented as 2 channel VBR AAC LC by the broadcaster (e.g. Freeview), may be left as obtained from the source.
   Audio which is broadcasted as AAC LATM or LOAS must have the headers converted to AAC ADTS without transcoding.
        8.2.8) Suggested command line: eac3to in.ac3 stdout.wav -downStereo -normalize | qaac --tvbr 82 --quality 2 --ignorelength - -o out.aac
    8.3) Multiple language audio tracks are allowed.
        8.3.1) The default audio track must be the language intended for release (e.g. An English release containing English, German and Russian audio tracks, must have the default flag set on the English track).
        8.3.2) The correct ISO 639 language code supported by MKVToolnix must be set for all secondary audio tracks, default may be left undefined.
   In situations where the language is not supported by MKVToolnix, 'und' must be used.
    8.4) If the original language of a title is not English:
        8.4.1) An English dubbed track is allowed as a secondary audio track.
        8.4.2) Releases containing only a dubbed audio track must be tagged as DUBBED.
    8.5) Dupes based on multiple audio tracks or audio format are not allowed, use INTERNAL.

9) [ Glitches / Missing Footage ]
    9.1) Where audio or video issues are unavoidable due to a live-broadcast or mastering issues, a release must not be nuked until a valid proper, repack or rerip which does not exhibit the same flaw is released.
    9.2) Scrolling or other alert messages added by the broadcasting station (e.g. Weather or Amber alerts) appearing for a cumulative total of at least 30 seconds throughout the entire release is considered a technical flaw.
    9.3) Video frame abnormalities (e.g. Abnormal snipes/pop-ups, banner advertisements that do not fade out entirely) as a result of broken splicing originating from the broadcasting station is considered a technical flaw.
    9.4) Missing or repeated video footage without any loss of dialogue must be at least 2 seconds long at any one instance to be considered a technical flaw.
        9.4.1) Except in situations where on-screen text is lost due to missing footage. Loss of on-screen text is considered a technical flaw.
        9.4.2) Except in situations where minor missing or repeated video footage flaws are present throughout the majority of the release. Excessive flaws such as these are considered a technical flaw.
            e.g. Video frame glitches occurring every 2 minutes throughout the entire release but only in the amount of 1 second per instance, is considered excessive and a technical flaw.
                 Repeated footage occurring every 5 minutes throughout the entire release but only in the amount of 1.5 seconds per instance, is considered excessive and a technical flaw.
                 Video frame glitches of 1 second per instance occurring 6 times throughout the entire release is NOT considered excessive or a technical flaw.
    9.5) Audio which drifts at least 120ms at a single point or a total of at least 120ms between multiple points throughout the entire release is considered a technical flaw.
        e.g. Sync drifting +120ms after 10 minutes is considered a technical flaw.
             Sync drifting +80ms after 5 minutes, -40ms after 15 minutes, for a total of 120ms, is considered a technical flaw.
    9.6) Glitches that occur in any audio channel present (e.g. L, R, C, SL, SR) are considered a technical flaw.
        9.6.1) Glitches are defined as, but not limited to: missing dialogue, repeated dialogue, inability to understand dialogue, bad channel mix, large gaps within playback, persistent clicks/pops/muted/echoing/muffled audio.

10) [ Editing / Adjustments ]
    10.1) Minor adjustments to video or audio tracks (e.g. duplicating or removing frames, channel count) in order to prevent issues with playback or sync is allowed.
    10.2) Multi-episode releases with no clear delineation between episodes (e.g. end credits) must not be split.
    10.3) Including previously-on footage is optional, but recommended.
    10.4) Including upcoming/teaser/scenes from the next episode footage found at the conclusion of an episode is optional, but recommended.
    10.5) Credits must be included if they contain unique show content. (e.g. bloopers, outtakes, dialogue, unique uninterrupted soundtrack, in memory of message)
        10.5.1) End credits must only be considered optional if they do not contain unique show content (e.g. regular plain credits with or without promos), and may be removed at the discretion of the group.
        10.5.2) A simulcast which does not contain unique content in the credits cannot be propered from a primary broadcaster which contains unique content, use EXTENDED.
        10.5.3) If a different broadcaster or re-broadcast of a show contains unique content not present in the original broadcast, the first release cannot not be propered, use EXTENDED.
   In situations where a unique uninterrupted soundtrack is the only additional unique content included in the credits, use of EXTENDED is not allowed, use INTERNAL.
   It is recommended, but not required, to include unique content included in the credits that was omitted from the original broadcast.
    10.6) Inclusion of bumper segments, 5-20 second segments containing coming up/preview/backstage footage (e.g. SNL, Cops) is optional and at the discretion of the group.
        10.6.1) In situations where bumper segments have been omitted in the first release, a secondary release which includes all bumper segments is allowed and must be tagged as UNCUT.
        10.6.2) In situations where bumpers are included:
   All bumper segments must be free of any technical flaws.
   All bumper segments must be included, missing any bumper segment is considered a technical flaw.
        10.6.3) Small segments containing actual show content, not containing coming up/preview/backstage footage, are not considered as bumper segments (e.g. Talking Dead, Comic Book Men, Portlandia).
    10.7) Any unrelated video (e.g. commercials, rating cards, viewer/content warnings), regardless of duration (e.g. 1 faded/half opacity frame or 10 seconds) must be completely removed.
        10.7.1) Content warnings can be retained or removed at the discretion of the group, except when they are intended by content creators and must be retained (e.g. Tosh 0, Robot Chicken, South Park, Law and Order SVU).
   This does not apply to scripted or animation content. Content warnings not intended by content creators must always be removed in these cases.
   Following the opening segment for non-scripted and non-animation content, all content warnings which precede each segment must be removed.
        10.7.2) Sponsorship advertisements which are integrated into show content and cannot be removed (e.g. Jimmy Kimmel, Talking Dead, Deadliest Catch) are exempt.
        10.7.3) Show transition cards appearing at the start or end of segments on some broadcasters (e.g. Seven, Channel 4, ITV1) can be retained or removed at the discretion of the group.
        10.7.4) Opening and closing interleaves (e.g. HBO opening animation, ... presents, this has been a ... production, ... original series) can be retained or removed at the discretion of the group, except when they contain show content and must be retained.
    10.8) Any unrelated audio (e.g. alerts, commercials), regardless of duration (e.g. 100ms or 10 seconds) must be completely removed.
        10.8.1) Except when a broadcaster (e.g. ABC) splices unrelated audio into the beginning of a segment, that does not result in sync issues.

11) [ Subtitles ]
    11.1) Subtitles for English spoken titles without foreign dialogue are optional, but encouraged.
    11.2) English spoken titles with foreign dialogue must include a separate subtitle track for forced subtitles.
        11.2.1) Foreign dialogue subtitle tracks must be set as forced and it is considered a technical flaw if not done correctly.
        11.2.2) In situations where the source video stream contains hardcoded subtitles for English spoken titles with foreign dialogue, a separate subtitle track for the forced subtitles is not required.
        11.2.3) If a broadcaster which is primarily English spoken (e.g. FOX, BBC) does not contain hardcoded subtitles for scenes with foreign dialogue in the video stream, then forced subtitles are not required but recommended.
    11.3) Non-English spoken titles without hardcoded subtitles must include an English subtitle track set as forced before it is considered to be an English release.

                 Release B does not dupe Release A: 1451572202 û 1451572201 = 1, i.e. maximum variance allowed.
                 Release C dupes Releases A and B: 1451572203 û 1451572201 = 2, i.e. 2 > 1.
        18.1.3) In situations where a release is found to contain a technical flaw, same second dupes which do not exhibit any technical flaws must be considered the final release. Groups may release a DIRFIX to PROPER for their original release, but it is not required.
            e.g. Release A and Release B are released at the same time. Release A is nuked as containing glitches, Release B then becomes the de facto release and a DIRFIX to PROPER may be released.

21) [ Ruleset Specifics ]
    21.1) In the absence of a country specific ruleset, this ruleset must be considered the ONLY official ruleset for TV-X264-SD. It supersedes all previous revisions, rulesets and precedents.

        21.1.2) The naming standards listed in this document must only take effect once a current running season has ended. Any existing naming schemes must be used in the event of missing episode(s) from older seasons being filled.
    21.2) When releasing with foreign language tags (e.g. SWEDISH, FRENCH, POLISH), all occurrences of the word 'English' in sections 5, 8 and 11 must be replaced with the tagged language.
            e.g. POLISH, rule 5.6 becomes "Non-Polish spoken titles with hardcoded Polish subtitles must be tagged as SUBBED.".
        21.2.1) Foreign language tags must represent the language intended for release, the following rules apply to Non-English releases only.
   Already established and widely adopted compact tags for subbed, dubbed and language, are allowed (e.g. PLDUB, SWESUB, SUBFRENCH, NLSUBBED).
   The DUBBED tag may be omitted or included at the discretion of the group.
                e.g. French TV series airing in Sweden with French audio and Swedish hardcoded subtitles must be tagged as SWEDISH.SUBBED or SWESUB.
                     Danish TV series airing in Poland with Polish dubbed audio and no hardcoded subtitles must be tagged as POLISH, POLISH.DUBBED or PLDUB.
                     Greek TV series airing in Greece with Greek audio must be tagged as GREEK.
   Soft-subbed releases are not allowed when the primary audio track is not the language tagged as, use INTERNAL or SUBPACK.
                e.g. Game.of.Thrones.S01E01.SWEDISH.HDTV with English audio and Swedish soft-subs is not allowed.
                     Game.of.Thrones.S01E01.DANISH.SUBBED.HDTV with English audio and Danish hard-subs is allowed.
   Hard-subbed releases dupe SUBPACK when the primary audio track is not the language tagged as, use INTERNAL.
                e.g. Game.of.Thrones.S01E01.TURKISH.SUBBED.HDTV with English audio and Turkish hard-subs dupes Game.of.Thrones.S01E01.TURKISH.SUBPACK.
        21.2.2) Releases with foreign language tags only dupe releases with the same foreign language tags.
                e.g. Game.of.Thrones.S01E01.SWEDISH.SUBBED.HDTV does not dupe Game.of.Thrones.S01E01.POLISH.DUBBED.HDTV or vice versa.
                     Game.of.Thrones.S01E01.FINNISH.SUBBED.HDTV does not dupe Game.of.Thrones.S01E01.HDTV or vice versa.
    21.3) The following definition of keywords throughout this ruleset are as follows:
        21.3.1) Must: the rule is explicit in the definition and is compulsory.
        21.3.2) Should: implies the rule is a suggestion, and is non-compulsory.
        21.3.3) Can or may: implies the rule is optional, and is non-compulsory.

Le conteneur Matroska (MKV)

Séries TV: la scène délaisse le conteneur MP4 et passe au MKV photo 1

Au lieu d’utiliser le .MP4 comme extension fichier, toutes les releases seront en .MKV à partir du 10 avril 2016.

Notez que le conteneur Matroska est déjà) utilisé depuis de nombreuses années pour les releases en HD donc ce qui change, c’est que ce format sera aussi imposé pour les fichiers SD.

Ce qui risque de coincer, c’est la compatibilité du format : tous les appareils ne peuvent pas lire le MKV nativement. Il a d’ailleurs fallu attendre plusieurs années pour que la Freebox par exemple reconnaisse le MKV. Il faudra donc pour certain(e)s mettre à jour leur matériel ou firmware, selon ce que vous utilisez.

Il n’y aura pas de conversion des fichiers MKV en MP4 mais vous pouvez toujours convertir des fichiers MKV en MP4 facilement en quelques clics avec HandBrake si nécessaire.

Premières réactions

Evidemment, ce changement soudain et péremptoire a causé l’ire de certains utilisateurs, qui n’ont plus eu accès à leur dose de fichiers MP4. Mais la scène n’a jamais eu cure du grand public et a toujours dicté ses propres règles donc mieux vaut profiter du changement et s’adapter.

Exit donc le MP4, et bienvenue au MKV !

    • Oui mais au final, on se rend compte que l’organisation est loin d’être anarchique : quand on regarde les spécificités techniques, on voit vite que ce ne sont pas des petits rigolos! Par contre, tout est imposé, c’est marche ou crève.
