-Release 2: June 07, 2007-

The High Definition x264 encoding scene has the goal of creating rips of HDDVD and BluRay
sources that can be played by the majority of end users. Specific hardware (other than
something higher then a mid-range Pent 4) should never be required to play releases. 
The goal is for these to be burnable to a DVD media source, playable on an HTPC. We are
not releasing these to be re-authored onto HDDVD or BluRay media. These rules will be 
constantly updated to adjust for new audio formats that are playable.

We have gotten together and discussed file sizing. DVD9 causes a much too high bitrate
for releases around the 2 hour long mark. In reality leads to longer download times
and more space being used on your hard drives for no real season. In addition, the higher
bitrate causes playback to be tougher for lower end machines. Our goal is to reach as many
people as possible, so this is an attempt to adjust for download times and playback.

~Previous Releases~
These audio rules do not apply to previous releases, and propering for those reasons will
not be tolerated. Groups who have released eac3 in the past have the option to repack, but 
this isn't mandatory. Common sense rules such as cropping are properable.

1.1)  RAR/SFV/NFO needed.
1.2)  Rar's can be 50mb, 100mb or 150mb. Use your best judgment.
1.3)  Releases should be packed into mkv container.
1.4)  NFO must contain information on Audio and Video Bitrate.
1.5)  BluRay and HDDVD Sources dupe each other.
1.6)  Suggested Directory Format (not a properable reason):
1.7)  NO intros, outros, betweenos, or any other form of defacement of the film will be tolerated.
1.8)  Credits must not be removed
	1.8.1) Can be encoded at a lower bitrate provided they don't contain any scenes 
		(bloopers, story, etc).
1.9)  A sample roughly 60 seconds in length is required. 
	1.9.1) It must be cut from the final release and not encoded separately.
	9.2) Must be put within a director named "Sample".

~Total Sizes~
2.1)  Final file size must be DVD5, 1.5xDVD5, or DVD9 size
2.2)  A size of 0.5xDVD5 is acceptable for animated movies ONLY.
2.3)  Releases should be within 5% of projected file size.
2.4)  DVD9 should be used only in cases of long movies, or high action movies.
2.5)  Propering a release that could have been a bigger size is not valid, unless below minimum bitrate.
2.6)  2x DVD5 is NOT allowed.
2.7)  For weird movies like LOTR, you may deviate from rules. Please use a multiple of 0.5xDVD5.

3.1)  No EAC3, DD+ TRUE HD, or DTSHD audio until there is practical Windows and Linux support.
	3.1.1) This does not include VMWare or alienating any group of users.
	3.1.2) The solution should be a reasonable codec that has a high compatibly rate.
3.2)  Currently accepted audio:
	3.2.1) FLAC audio is allowed ONLY if created from LPCM or TRUEHD sources.
	3.2.2) Source AC3 or DTS from a BluRay
	3.2.3) AC3 transcoded from source LPCM, DD+ or EAC3
3.3)  All audio should be proper 5.1, with correct channels, except in the case of stereo/mono 
3.4)  All AC3 audio with HDDVD releases should be at 640kbit/s, unless the disc only comes with
	lower bitrate audio.
3.5)  Releases may only contain one audio track muxed into the mkv container.
	3.5.1) Use English only if English is the native audio.
	3.5.2) If English audio is not native:
    English Subtitles must be included
    Subs should not be HUGE AND UGLY. Check your settings!!!
    Subs should be any format that will mux into an mkv that is text-based.
    English dub is allowed as a secondary audio track.
	3.5.3) Other language audio may be released as a SECOND release with a bat file
		that will remux that audio into the release.

4.1)  Minimum bitrate should be 4mbit/s
	1.1) Animated movies allowed less than 4mbit/s bitrate.
4.2)  All movies must be at their original framerate.
4.3)  Use at least 3 bframes
4.4)  Must use a minimum encode of 2 passes.
4.5)  Crop the black borders from the source.
	- Sharp edges in the encoded region will lead to border bits needing
		more information then they should.
4.6)  Height and Width of rip must be mod 16.
4.7)  720p refers to a MAXIMUM resolution of 1280x720.
	4.7.1) Acceptable resolutions are:
		- x528 = 2.40 AR
		- x544 = 2.35 AR
		- x688 = 1.85 AR
		- x720 = 1.78 AR
	4.7.2) Rare occasions where a movie if VERY wide, use appropriate settings.
4.8)  Use the aspect ratio on the source, not what IMDB says.
4.9)  Custom Matrices are allowed.
4.10) --deblock can be varied depending on the source.

5.1)  Multi-language subtitles cannot be used as a basis for a dupe
5.2)  Subtitles are to be MUXED into the mkv container, but MAY NOT be burned in to the video stream. 
5.3)  "Subs" directories are forbidden.

Recommended settings (if you care about quality) are at LEAST:

Pass 1:
x264.exe --pass 1 --bitrate x --threads auto --thread-input --bframes 3 --me dia --ref 1 --subme 1 --no-dct-decimate 
--partitions none --progress --no-psnr --no-ssim --output NUL

Pass 2:
x264.exe --pass 2 --bitrate x --threads auto --bframes 3 --b-pyramid --bime --weightb --b-rdo --me umh --ref 5 --mixed-refs 
--subme 7 --trellis 1 --8x8dct --no-fast-pskip --progress --no-psnr --no-ssim --output x.mkv
