    2.4.2 Rescaling movies

    -

    Often the need to resize movie images' size emerges. Its reasons can be many, - examples are decreasing output file size, encoding SVCDs to DivX. Ripped DVDs - are mostly rescaled, for example a 4:3 DVD should be 640x480, especially - when you want it to fit to 1 CD, and have good quality at the same time. - SVCDs have 480x480 size, and their header contains the aspect ratio the - player should use (Ex.: 480x480 + 4:3 = 640x480). However when encoding to - AVI (DivX) files, you have be aware that AVI headers don't store this - value. Thus, the only solution is rescaling.

    Often the need to resize movie images' size emerges. Its reasons can be + many: decreasing file size, network bandwidth, etc. Most people + even do rescaling when converting DVDs or SVCDs to DivX AVI. This is bad. + Instead of even you doing so, read the Preserving + aspect ratio section.

    The scaling process is handled by the 'scale' video filter: - -vop scale=X:Y. Its quality can be set with the + -vop scale=widht:height. Its quality can be set with the -sws option. If it's not specified, MEncoder will use 0: fast bilinear.

    2.4.8 Preserving aspect ratio

    + +

    DVDs and SVCDs (i.e. MPEG1/2) files contain an aspect ratio value, + which describes how should the player scale the video stream, so humans + won't have egg heads (ex.: 480x480 + 4:3 = 640x480).

    + +

    There is.

    + +

    MPEG4 has an unique feature: the video stream can contain + its needed aspect ratio. Yes, just like MPEG1/2 files (DVD, SVCD). + Regretfully, there are no video players outside which support this + attribute. Except MPlayer.

    + +

    This feature can be used only with libavcodec's mpeg4 + codec. Keep in mind: although MPlayer will correctly play the created file, + other players will use the wrong aspect ratio.
