how do i resize a video to fit a custom border

Hi, Alex,

You can try this: Create a new project. Put your video into it and also drag in a black background. Overlay the video onto the black background using Picture in Picture. With PIP, reduce the size of the video to the size you want. Click on the blue reset button to apply your settings. Then share it out to your desktop and drag it into your original project. You now have a smaller video, with no cropping, on a black background. Again using PIP, overlay your boarder over the reduced sized video and adjust its position so that it properly overlays the video. It may take a little trial and error.

Picture in Picture is the normal way that I would recommend to fit a picture to a frame image. Like this:

Is there some reason why you don't want to do it that way?

A screen shot of what you are trying to do might be helpful.
