According to the Cin-CV manual:

    *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
    explores in more detail these settings. It is in Russian but easily
    translatable with GoogleTranslator, DeepL or similar.

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