  • "Ganool" Encodes

    Hello,

    Does anybody have any information on how the Ganool group at Ganool.Video - Free Download, Stream, or Watch Online Your Movies. encode their movies? Despite very low file sizes (1.5 GB for a 1080p) their encodes seem pretty awesome. If you have information and would like to share, please feel free to do so here.


    Thank you very much,

        Ganool use x264 codec inside a mkv container, The best x264 encoders are MeGUI and ripbot x264 (MeGUI is my preference)

        Their encodes are predominantly filesize based ,So are most likely Bitrate based, 800KBps - 1200KBps (720p) | 1600KBps - 2200KBps (1080p)
        A quick way to check basic settings is to take one of their files and check it.

        You can find the basis structure and settings of any A/V file using media mediainfo

        This is where you will find some encoders instruction,, Tho it cant tell you of any filters applied ( HD source requires none)

        Output Looks like this :
        Spoiler Alert!
        ID : 1Format : AVC
        Format/Info : Advanced Video Codec
        Format profile : [email protected]
        Format settings, CABAC : Yes
        Format settings, ReFrames : 5 frames

        Codec ID : V_MPEG4/ISO/AVC

        Width : 640 pixels
        Height : 480 pixels

        Frame rate mode : Variable
        Color space : YUV
        Chroma subsampling : 4:2:0

        More information on with they mean can be found in the MeGUI

          [MENTION=161984]SUpper[/MENTION] - All their encodes are either 720p or 1080p and the file size is smaller than what you may see in a "HANDJOB" encode in PTP. Is this possible? Yes, but how?

            The more extensive the analysis the better the chance that the encoder (MeGUI) will have to make good decisions about what details to drop , and to better distribute the allocated bitrate ,ie scenes/frames with less motion ,or less complex lighting |'ect require less bit-rate aiding compression ,, action scenes require more bitrate and higher motion/vector analysis to capture its intended impact ,,
            Seen in good rls nfo and are highlighted in my last post and apply to x264

            A few things to note:

            Source
            The most important thing full stop!!


            Profiles
            These are base setting that hold the parameters that can be tweaked ,

            Baseline @ $ avoid anything that uses this
            [email protected] 3 > 4 ,, Watchable SD content , comparable with terrestrial broadcast
            [email protected] 3 / 3.1 / 3.2 Is the basic modes used for WEB based stream content , and not suitable for HQ HD content , its choice of itunes @ least up until late
            [email protected] > 5 Is the standard for HQ HD Content .. anyone can open a modern encoder program and make decent rips from BD with just the 4.1 profile 2Pass

            Encoding Mode

            CRF

            The way constant quality encoding is usually done in one pass, it keeps up a constant quality by compressing every frame of the same type the same amount.
            Less accurate analysis and uses looser estimates leading to less efficient Compression,, There is little to no indication as to the filesize that will be output
            The CRF is set between 0 - 51 with 0 being lossless, 18 - 22 will give Good results

            Found in "scene" encodes its basic but ensures all rls's are of good quality and meet scene standards..


            2 Pass encoding

            In the first pass of two-pass encoding, the input data from the source clip is analyzed and stored in Tree/stats and log files.
            On the second pass, the collected data from the first pass is used to achieve the best encoding quality and more efficient compression .
            In video encoding, two-pass encoding is usually controlled by the bit-rate range setting (minimal and maximal allowed bitrate) or by the target video file size setting.


            This allows for greater Encoder control and with practice will give better results

            EG https://image.torrent-invites.com/im...YMumr12YDk.png >> 1920x1080 @ 1 449 Kbps = 1.4GB

            This was encoded by a "friend" , Files like these are not to everyone taste, but the skill applied here > scene size rips (8.5GB) Gotta respect that imo


            # Add more on motion, pixel/sub pixel ,B/ref frames ect , all that good stuff to post in tuts
