According to the Cin-CV manual:
http://cinelerra-cv.wikidot.com/cincv-manual-en:project-attributes#toc4

    *W Ratio, H Ratio*
    Sets the ratio of the new canvas size (W, H) to the old (previous)
    canvas size (W, H). The new canvas size is recalculated based upon a
    certain factor in the W Ratio, H Ratio fields. A practical use-case:
    The current resolution is 640x480, and for some reason you want it
    to be 1.33 times wider. You don't have to calculate what 640x1.33
    is; you type 1.33 into the "W" input instead, and Cinelerra
    calculates it for you. This tutorial
    <https://linuxvideoediting.blogspot.com/2023/08/canvas-w-ratio-h-ratio-cinelerra.html>
    explores in more detail these settings. It is in Russian but easily
    translatable with GoogleTranslator, DeepL or similar.

The latter Tutorial can be translated ......
