The first part of a standards document usually defines the format properties for the material, like codec, bitrate, resolution, file type and file size. Creators of the standard usually do comprehensive testing to find optimal codecs and settings for sound and video to maximize image quality in the selected file size.

When choosing file size, the limiting factor is the size of the media to be used (such as 700MB for CD-R). The standards are designed such that a certain amount of content will fit on each piece of media, with the best possible quality in terms of size. If more discs are required for sufficient quality, the standard will define the circumstances where it is acceptable to expand to a second or third disc. Newer video standards moved away from the size constraints and replaced them with a quality based alternative such as the use of CRF.
When choosing the file format, platform compatibility is important. Formats are chosen such that they can be used on any major platform with little hassle. Some formats such as CloneCD can only be used on Windows computers, and these formats are generally not chosen for use in the standards.
The sizes of the archives within the distributed file vary from the traditional 3" floppy disk (1.44 MB) or extra-high density disk (2.88 MB) to 5 MB, 15 MB (typical for CD images) or 20 MB (typical for CD images of console releases), 50 MB files (typical for DVD images), and 100 MB (for dual-layer DVD images). These measurements are not equivalent to traditional measurement of file size (which is 1024 KB to a MB, 1024 MB to a GB); in a typical DVD release, each RAR file is exactly 50,000,000 bytes, not 52,428,800 bytes (50 megabytes in binary prefix).
Formerly, the size of volumes were limited by the RAR file naming scheme, which produced extensions .rar, .r00 and so on through .r99. This allowed for 101 volumes in a single release before the naming switched to s00, s01 and so on. For example, a DVD-R image (4.37 GiB), split into 101 pieces, produces volumes smaller than 50 MB. The new RAR naming format, name.part001.rar, removes the limit, although the individual split archives continue to be 50 MB for historical reasons and because the old RAR naming format is still being widely used.
Different compression levels are used for each type of material being distributed. The reason for this is that some material compresses much better than others. Movies and MP3 files are already compressed with near maximum capacity. Repacking them would just create larger files and increase decompression time. Ripped movies are still packaged due to the large file size, but compression is disallowed and the RAR format is used only as a container. Because of this, modern playback software can easily play a release directly from the packaged files, and even stream it as the release is downloaded (if the network is fast enough).
MP3 and music video releases are an exception in that they are not packaged into a single archive like almost all other sections. These releases have content that is not further compressible without loss of quality, but also have small enough files that they can be transferred reliably without breaking them up. Since these releases rarely have large numbers of files, leaving them unpackaged is more convenient and allows for easier scripting. For example, scripts can read ID3 information from MP3s and sort releases based on those contents.
Rules for naming files and folders are an important part of the standards. Correctly named folders make it easier to maintain clean archives and unique filenames allow dupecheck to work properly. There's a defined character set which can be used in naming of the folders. The selected character set is chosen to minimize problems due to the many platforms a release may encounter during its distribution. Since FTP servers, operating systems or file systems may not allow special characters in file or directory names, only a small set of characters is allowed.[ruleset 2] Substitutions are made where special characters would normally be used (e.g. ç replaced by c) or these characters are omitted, such as an apostrophe. This can happen automatically by site scripts. As a note, spaces are explicitly disallowed in current standards and are substituted with underscores or full stops.[ruleset 3]
There are several standards to release movies, TV show episodes and other video material to the scene. VCD releases use the less efficient MPEG-1 format, are low quality, but can be played back on most standalone DVD players. SVCD releases use MPEG-2 encoding, have half the video resolution of DVDs and can also be played back on most DVD players. DVD-R releases use the same format as retail DVD-Videos, and are therefore larger in size. Finally DivX, Xvid, H.264/MPEG-4 AVC and recently HEVC releases use the much more efficient MPEG standards. Generally, only middle to top-end DVD players can play back DivX or Xvid files, while Blu-ray players are required to handle H.264 files.
Scene rules require the releasing group to spread theatrical VCDs in .bin/.cue files that can be burned on a CD. Although often the CD size is dictated by the length of the movie or video. One movie typically uses two CDs, although length may force the release to be a 3 or 4 CD release. The source of these theatrical releases is typically analog, such as CAM, telecine or telesync releases (movies recorded by a camera in theatres, often with external audio sources). VCDs from other sources such as DVD, VHS, TV, Pay-Per-View specials, Porn or Anime may also be released in the .mpg or .asf format. DVD and VHS rips are only allowed if there was no screener released before.[ruleset 6] The scene VCDs popped up in 1998, but digital unlicensed versions of films already appeared in early 1997 on private FTP networks. Eviliso, VCD-Europe, FTF and Immortal VCD are groups that have released VCD movies. In 1999 there were 15 to 20 groups.
Because of its low quality, VCD releases declined in favor of SVCD and XviD. VCDs are often larger than these higher quality files, making VCDs even less attractive. VCDs once used for music videos got their own set of standards on October 1, 2002.[ruleset 7]
Scene rules require the releasing group to spread SVCDs in .bin/.cue files, that fit on 700 MiB CDs.[ruleset 8] One movie typically uses two CDs, although length may force the release to be a 3 or 4 CD release. Content source is sometimes analog, such as Cam, Telecine or telesync releases. Also R5, DVDSCR or retail DVD is used as SVCD source. The advantage of SVCD is that it can be played on any standalone DVD player, but when DivX-capable players are taking over the market and more bandwidth becomes available to download DVDRs, SVCD became obsolete. Around 2007, the stream of SVCD releases from the scene died out.
MPEG-4 release standards are set in the so-called TDX rules.[ruleset 10] The DivX codec originally gained popularity because it provided a good compromise between film quality and file size. Approximately 25% of the space occupied by DVD is enough for a DivX encode to have DVD quality output. The first standards were created by meetings and debates of Team DivX (TDX) in 2000. This group consisted of the leaders of the top 5 DivX releasing groups, topsite operators along with rippers and encoders. It was formed because they thought "the new Div/X scene was a bit unmoderated, sloppy and pretty much a free-for-all."[ruleset 1] iSONEWS published the first standards on April 26. Earlier, on March 16, the database started to carry a DivX section on their website. A week later Betanews noticed the popularity of the then recently released DivX codec throughout IRC channels and asked whether this was a new threat to DVD after the DeCSS utility. The 2001 revision of the standards were organized by different people from iSONEWS.[ruleset 9] It consisted of 15 groups and signed by 18. This was the last one of the listed rulesets covering pornography.
The once generally accepted TDX2002 ruleset requires movie releases to contain a DivX 3.11 or Xvid encoded video stream with an MP3 or AC3 encoded audio stream in an AVI container file. Movies are released in one, two or more 700 MiB files, so that they can be easily stored on CD-R. Two or four TV show episodes usually share one CD, hence 175 or 350 MiB releases are common. 233 MiB (three episodes per CD) are more rare but not forbidden, and are often used for full 30-minute programs with no adverts. 233 MiB is more used on whole season rips from retail sources or on single episodes that have a longer runtime. In July 2002, around the release of the new TDX2K2 ruleset, Xvid releases started to pop up. DivX with SBC was retired. VCDVaULT was the pioneer in promoting Xvid to the scene. In 2003, TheWretched believed it was time to update the standards again and a few tweaks were in order. Thereafter they found the lack of info groups put into the NFO inexcusable: It isn't only about the flashy ASCII art, the content matters.
The TDX2002 ruleset was followed by TXD2005.[ruleset 11] Because all DivX codecs are banned in this new ruleset, TDX became TXD: The XviD Releasing Standards. There is a rebuttal against this revision, proving it to be flawed in several aspects. Higher resolutions are not allowed. More efficient formats such as AVC and AAC have not been adopted yet, but are still being pushed by some release groups. There are also considerations to replace the old proprietary AVI file format with a modern container such as MP4 or MKV that can include multiple audio streams, subtitles and DVD-like menus. However, few standalone DVD players support these formats yet, and cross-platform playback is an important consideration. Nonetheless the introduction of MPEG-4 playback capabilities in standalone DVD players was a result of the huge amount of TDX-compliant movie material available on the internet. 041b061a72
