I'm trying to do what I thought would be the simplest thing, which is to crop a portion of a screenshot of a webpage and zoom in on it (yes, I'm new to Blender).
After I've imported the image and added "Effect Strip" > "Transform" I can crop "Top" and "Right" (if I check "Image Offset" that is, otherwise it STRETCHES the image), but changing values in "Bottom" and "Left" just MOVES the image, it doesn't crop it.
What am I doing wrong?
