I have a video that is in HD resolution that I'd like to rescale to a smaller size so it can be viewed on smartphones.
In the Render Project dialog, I select check "Rescale" on, and set it to 480X270.
However, when it renders, it does not rescale it, but instead renders a cropped 480X270 sized section from the top left of the video. So all one sees is a corner of the action.
How do I render a scaled down version of my video?

I'm using Kdenlive 0.9.2 on Ubuntu 12.10.
