    Video post processing

    ok heres some tidbits on why ffdshow and a good video decoder is important for watching dvds/movies on pc.


    Intervideo video decoder + ffdshow resize + avisynth


    Nvidia video decoder + ffdshow resize + avisynth


    Nvidia + ffdshow resize + No avisynth


    Dscaler + ffdshow resize + avisynth

    hehehehhe think most dun understand...
    OTOH adding avisynth looks like adding too much EE to mu liking...those with digital display may be put off

    its something like a scripting tool for video that allows users to create plug ins.


    the below stolen from wiki

    AviSynth communicates with any program that supports AVIs through the video for windows system by acting as a "fake" AVI file. It can apply a large variety of editing and processing functions (called filters) to a video stream before passing along the results as if it were a legitimate file being read. Filter capabilities include trimming, cropping, deinterlacing, inverse telecine, loading and splicing still images, doing color corrections, denoising, and many other things.

    Technically, it acts as a codec for AviSynth scripts, which are text files written in the AviSynth scripting language. The scripting language can be extended through the use of plugins. A plugin list is maintained at AviSynth Filter Collection.

    AviSynth filters work in several color spaces including RGB, YUY2 and YV12. This is necessary to allow all kinds of video input and output. Also, certain functions only work on certain colour spaces, making conversion mandatory.

    Just some info on resolutions from the PowerStrip Forums

    Plasma displays normally include very good scalers, which allow them to be "compatible" with high definition signals: 1080i and 720p. More than other display types, plasma marketing can be very confusing. To keep it simple, think of there being only 4 types of panels:

    1. WVGA: 852x480, usually labelled EDTV
    2. ALIS: 1024x512, but usually marketed at its interlaced equivalent of 1024x1024
    3. XGA: 1024x768, usually marketed as HD plasma because it can resolve 720 progressive lines
    4. WXGA: 1366x768, also marketed as HD because it can resolve 1280x720 natively; some will even accept 1080p and scale that to the native resolution

    *All* of these plasmas can be "compatible" with 1080i and 720p, if they're designed to recognize the incoming signal and scale it to the native resolution. The difference between them isn't in the signals they are compatible with, but what they scale it to. As a general rule when connecting a display to a PC you want to avoid scaling altogether and configure the PC for the plasma's native resolution.

    1. WVGA: if 852x480 is not available, shoot for 848x480 or 856x480
    2. ALIS: these are nice for CE devices but ill-suited for HTPCs; shoot for 1024x512 (although some people prefer 1024x576)
    3. XGA: 1024x768, but because these plasmas have non-square pixels, many people prefer a bit of scaling and use 1280x768, 1360x768 or 1368x768 instead to get a better widescreen aspect ratio
    4. WXGA: if 1366x768 isn't available, shoot for 1360x768 or 1368x768

    Hmm tried all the filter combi

    Followed the advanced guide. mpc + ffdshow resize (2x)+ avisyth + all the scripts (denoisers, sharpeners) + dscalar decoder/nvidia decoder + rclocker. Computer usage at 70+% and couldn't play the dvd. Played an hdtv version of smallville, turned up super laggy and mosiac looks.

    Guess it really requires a good system.

    My system:
    X2 4600+
    DDR400 4GB Ram
    7900GTX
    Hitachi tk250 on Raid 0.

    Gollum, u followed to the T in the guide?

    i gave up on postpocessing true hd content (720p 1080i 1080p).

    Normal dvd quality post process not a problem. just that true hd content my system went to its knees.
