    What are the best options for high quality and compactivity, I am currently using

    sony psp - Xvid - aac - 368x208 pixels - 16:9 - 29.97 - 384kbps Video Bitrate - (Ticked Box) High Quality, Stretch it, 48K Audio - 48000 Sampling Frequency - 2 Channels - 128kbps Audio Bitrate

    the video does come out slightly pixelated, sometimes looks better using H.264/AVC video codec, do I need to increase the video bitrate or what?

    please note I am converting from ripped DVD files (100% Top Quality)

    yes with a a full 29.97 frame rate you need to increase the video bitrate, 384 is to low for that frame rate, i recomend a minimum of 576 and it should probably be even higher

    I use 288 and 15 fps on a cell phone at 320*240 , 576 is double the bitrate to keep up with double the frame ratem too have the same amount of data per pixel per frame

    is there a bitrate calculator for this that doesn't determine the bitrate over the 'target size' (I want it to be dermined by the resolution and aspect ratio) and gives you a variety of video codecs (or do the video codecs not matter?)?

    several aspects to codecs,

    but most important in portable situations , is does the device have enough processing power, to de-compress a highly compressed stream and play it back it back without stutter or jumping

    my phone will play h.264

    but i find that mpeg4 with a slighlty larger file will give just a clean & sharp picture, with less strain on the processer, so movies playing from the 2gig memory card play smoother than h.264, even though techincaly the h.264 has more detail

    like my eyes can tell there is more detail on a 2.8 display, in an action movie, nada

    but how would I know how much video bit rate is appropriate for the resolution I have chosen and the not the target size?

    what is the screen resolution ? maybe i can give you a starting point suggestion.

    once you find the bitrate, that displays too your liking, the file size will always vary according to lenght and amount of movement/pixel change in the scenes

    but you can always use that bitrate

    try 288 for 15fps or under

    and 576 for 23.976 - 30 fps

    if you think the file size is too big you and try reducing the bitrate

    for 24fps and up I would NOT go lower than 386,

    when using SUPER and converting on PSP H264/AVC, is there a way of using 25fps, as the program only allows 29.97fps and I have 25fps videos, is there a way to change the Avisynth script thing? can Avisynth allow me crop my video too?

    I haven't tried using avisynth to frame serve to SUPER

    all i can say is use fit cd for an avisynth script, and try it

    drop the script in SUPER and see if it will work

  11. Nitro89: yes you can do almost anything with avisynth. I suggest you check out the wiki on internal filters
    http://avisynth.org/mediawiki/Internal_filters

    If you want an easier (i think better) way for psp conversions, I suggest ripbot264 which has a psp profile. You can also crop, resize, and change output speed in the options easily (it makes a script for you). Here is a sample collage of some of the options:

    Good Luck
